I've seen guys who are selling bows make a point of saying "no phenolic". Is phenolic considered bad? A shortcut to add strength? A cheaper material than using wood laminates? What exactly is it and what are the downsides? Thanks. ;)
Nope, it sure isn't evil! Evil is a whole other philosophical kettle of fish, and I'm pretty sure phenolic isn't on the official list of evil things.
Phenolic is compressed linen, methinks.
It comes under the topic of aesthetics - some people don't like it, others do. I like a broad variety of bows, some with phenolic, others without.
The "No phenolic" (similar to the "No CNC") advertising, is just another not-so-subtle crack at Black Widow, as they are renowned for their use of phenolic in their bows these days (although you can request their larger recurves without it). One thing is for sure: Whilst Black Widow bows will forever be knocked by some, I don't think anybody is game to knock the achievements made by folks around the world with Black Widow bows in their hands.
Oh, unless it is in an advertisement in the TradGang classifieds, in which case the owner is simply being clear about what his BW bow is made from (reading back, I wasn't sure if you were referring to ads in magazines or private classifieds).
Thanks, Ben. Yes, I was referring to the TradGang classifieds. Of course, I didn't really think it was evil...just trying to get some attention to the topic. ;) I am having a "bumble bee" Super Shrew made up...it will be Osage and either Ebony or phenolic. Just wanted to make sure there were no downsides to the phenolic.
"Phenolics are the result of polymerization between resin and a base material that can be paper, glass or cotton. The base material used is dependent upon the intended application of the finished product. Paper phenolics are used in the manufacturing of electrical components such as punch-through boards and household laminates. Glass phenolics are particularly well suited for use in the high speed bearing market."
Many bow makers have used phenolics for years. I can remember it in bows from the late 60's to present. It is very stable and is less effected by atmospheric conditions, such as humidity, than wood. It also adds weight to the bow which for some can be good or bad depending upon personal choices.
I love my phenolic Black Widow...it is another great addition to the traditional bowyers arsenal...some know how to use it well in their products while others don't. Just my .02 cents.

Good explanation...so, what do bowyers use as their base material?
I have a Bumblebee Shrew Classic Hunter with Osage and phenolic and also with a Bow Bolt. You will love it!

I like bows with alot of mass weight and Phenolic can really help get some added weight on a riser. I have a target bow made by Gerald Hickman, he made the entire riser out of Linen Phenloic. It is a very stable bow in the hand.
I bet that Shrew will look "wicked-deadly"!
Most bow makers use linen based phenolic.It is used on the tips for f/f build up and in the riser for mass and looks. Paper based is what you may find on some of the tips of older bows from the late fifties and early sixties. It would tend to crack at the tip, between string grooves on the back side.

The place I here no phenolic is on Black Widow where they use it in their limb wedges.I believe you pay extra for wood in the limb wedges.It doesn't bother me any te use of phenolic.
My new Morrison Shawnee riser is 100% phelonic NO WOOD and so far the hogs think it's real evil! I love it - each to his own.
Next to my DAS bow this is my favorite. It is a custom made (for me) Groves 56" take down. I had it made with 100% black phenolic. The weight and density of the phenolic make it super stable. I have put the same limbs on wood risers and they do not shoot as well as on the phenolic riser. There is nothing "evil" about phenolic risers.

Great replies...thanks. :thumbsup:
Phenolic in a riser is recommended by Craig Warren, the designer of the bow bolt, for use with the bow bolt for a 2-PC T/D bow. It is in fact stronger than the woods around it, unless the riser is built of 100% phenolic.

I think the deal is some people enjoy and appreciate wood.
Theres nothing evil about metal risers either but many people dont care for them.
QuoteI think the deal is some people enjoy and appreciate wood.
Yep, I've ordered a couple widow takedowns without the phenolic. I just don't care for the look of their bows with the black wedges.
Yes it is evil. It is made out of Demon Horn and the only glue that will set with it is made from the hooves of the Mares of Diomedes. :goldtooth:
Thank you vermonster13 for the straight facts surrounding phenolic. And thanks much for the laugh!
As someone else said, they just like wood. I love the beauty and grain evident in a bow made of the beautiful native and exotic woods we have available.
I'm sure the bows today that are made of phenolic with fiberglass and foam cored limbs are excellent bows. They would be super while hunting in a steady downpour; but bowyers please keep making bows that utilize wood in the riser and limbs.
I ordered my last Widow without phenolic for two reasons. I like the looks of wood better and most importantly the bow weighs much less.

Oh yeah, there is something evil about it.... It makes you want a bow that looks like this :saywhat: :

Enjoy your (evil) Shrew.... :thumbsup: ..
lets see if I can add a pic or 2 of some real "evil phenolic". (http://i185.photobucket.com/albums/x132/recurvehunter_2007/ATT6.jpg) :thumbsup: (http://i185.photobucket.com/albums/x132/recurvehunter_2007/kwykstykquiver.jpg) :archer: :archer:
Nice pics Sergio,,,Frank

See...I knew it. :D Great pics and information guys. I know I will love my Osage/phenolic Super Shrew.
Thanks Frank!
A phenolic riser may be slightly louder than a wood riser. If you want maximum mass (esp. good for short bows where stability is critical or for target shooting), phenolic is a good choice. If you want good mass but wood, consider ebony or another heavy wood. Phenolic is roughly 1/3 heavier than ebony.
Dymondwood is very heavy, too. The only problem with Dymondwood is it has a tendency to check.
Bill
working as a mechanical designer in a prototype machine shop, I can tell ya, the guys hate to machine the phenolic. Tough...very very tough stuff.
Did I ever tell ya about my phenolic bow idea ? ..... Oh good. Shhhhhhhhhhhhhhhhh Evil is as Evil does.... and this is on wicked good lookin idear. ;)
Bill,
I apologize before hand, but I disagree concerning your statement about Dymondwood having a tendency for checking. Dyamondwood is very stable as it is multi layers (about 1/32")of birch laminated together and impregnated under pressure with epoxy resin. The reason bowyers like it is because of it's strength and stability. Knife makers also use it for grip scales. I suppose you could sort of say it is similar to phenolic only instead of very thin linen or paper it is thicker wood.

wow great thread we were beating this around on the collecters forum also micarta virsus phenolic.Which I believe is the same thing and micarta is like a trade name maybe for a certin phenolic ? or something along those line.
As mentioned above the pre 1960 bow tip overlay type was paper macarta and did not last long.It was to thin and not very flexable cracked and got moisture under the overlay and then fell off.Bows built in the 1960's using it in the handles had lots of problems with cracking.Which actually had nothing to do with the material itself.Again great thread thanks bd
Actual Definitions for you.
Micarta is a composite of linen or paper fabric in a thermosetting plastic, originally used in electrical and decorative applications. Micarta was developed by George Westinghouse at least as early as 1910 using phenolic resins invented by Dr. Leo Baekeland. These resins were used to impregnate paper and cotton fabric which were cured under pressure and high temperature to produce laminates. In later years this manufacturing method included the use of fiberglass fabric, other resin types were also used. Today micartas are produced with a wide variety of resins and fibers and the term has evolved to generically refer to most resin impregnated fibre compounds. Common uses of modern micartas are as electrical insulators, printed circuit board substrates, and knife handles.
Phenolic is the name usually given to a resin made of phenol and an aldehyde. It is used anywhere rigid materials are needed, particularly to create moldings for consumer products, for some bearings, for insulation, and as a binder.
Phenolic may also be used as a term to describe the entire class of phenols. These are simple hydrocarbon groups, similar to alcohols. Phenolic compounds are varied, ranging everywhere from the heat agent in chili peppers to dopamine to the cresols from creosote. While the word phenolic may be used individually to refer to these compounds, the term phenolic compound is more appropriate.
Phenolic resins may be made by combining simple phenol with any number of aldehydes, but the combination made with formaldehyde, known as phenolic formaldehyde resin, or PF, is the most widely used. Phenolic resin was the first synthesized resin, and was marketed under the brand name Bakelite, which still exists. The majority of formaldehyde produced is used with phenol and other organic compounds to create resins, which are used extensively in industry.
Phenolic is the material used for most consumer fittings. Plugs on electronic devices, handles for pots and pans, and the screw-tops on most sodas are just a few applications for which phenolic is widely used. Its affordability and the ease with which it is molded make phenolic an ideal candidate whenever a cheap plastic is needed.
Phenolic is also used frequently as the binding agent to hold together composite woods, including chipboard and plywood. Phenolic is somewhat brittle as a binding agent, which is seen by some as a disadvantage, but it lets out very little smoke if it combusts, and at higher grades can be resistant to temperatures in excess of 370°F (185°C). As insulation, phenolic also sees a fair amount of use. Its easy setting and affordability make it ideal in some situations. Phenolic has a high thermal mass, making it a relatively strong thermal insulator in comparison to some other low-cost insulating solutions.
Sheets of material made from phenolic are popular as an alternative to acrylic, because of its high resistance to flexing. These flat plates of material may be used as tables for electric saws, hard floor mats, and even pick guards for guitars. Phenolic sheet is usually made by impregnating a core material, such as paper or fabric, with the resin and then catalyzing it.
Wow...I am glad I started this one. Loads of useful information. :thumbsup:
The last statement leads one to believe they are somewhat the same if impregnating a core or base material such as paper of fabric becomes ie linen macatra ??? bd
"Sheets of material made from phenolic are popular as an alternative to acrylic, because of its high resistance to flexing."
Flexing......How does a strip of linen phenolic rank in stiffness to say the same size strip of bubinga for example. If it's less, you're better off with bubinga unless mass is a higher priority then flexing.....O.L.
Phenolic made with fine thread cotton linen is extremely strong, much more so than wood. The stuff made with glass fibers is used in fighters,boat hulls and other applications where very rigid, damage resistant material is needed.
One thing to remember about phenolic is that you must avoid breathing it during grinding or sanding. If you can smell it your breathing it and it's bad cancer stuff.
Is micarta evil? Heck yeah! It's down right wicked!!! Here's the darkside of a Hummingbird and a Bob Lee.

Beauties, Rob! :thumbsup:
I love my phenolic Cascade Silver Hawk! The only thing I could see or feel is that the phenolic adds weight to the bow riser. Phenolic is strong but it's heavier then most woods given all things are equal. I'll shoot'em either way! mr.c
It is heavier than any wood because they are not equal in weight.
Keep in mind, some report a phenolic/micarta riser may be slightly louder perhaps because the phenolic/micarta is harder and transfers sound better.
Thanks for all the info on phenolic guys. Bill Kissner: That is a great looking Widow!
