Review Carbon Fiber molded into Curly / Quilted "wood" figure for scales / handles

New guy here - so go easy. I actually forged a rambo knife back in 84, and loved the whole process - even "set" the teeth prior to hardening / tempering.

Anyway, I recently developed a process to mold unidirectional CF and Kevlar fiber into wood figure like "flame" and "Quilted" figure because fiber replicates wood figure chatoyance exactly. I machine the panels flat, then any shape or roundover edge shows the light refractivity (Chatoyance) all the way through. So wild I even patented the process (why I'm in serious debt).

Waayyyy wilder than marbled or swirled uni, because there is a pattern in the waviness, not random, as I made the molds based on actual fiddleback and quilted figure, where viewers subconsciously equate the pattern to burled or curly figured wood, but the chatoyance is greater than that of the deepest figured quilted maple or burl walnut.

Currently marketing these sheets for fretboards and body "veneers" in the guitar industry, but always thought knife handles would be a potential market, although small, so never really pursued it until now that I have a few products like my Opalescent acrylic sheets in addition to the new solid figured CF.

I am assuming most won't see the advantage over common woven CF or marbled uni, which is why I am posting here to see if this has market value. I've seen woven and marbled CF at 40 bucks per 2 x 6 blank, and thought I could easily go less than that, but is it worth it for a few sq ft a year when my business is geared toward thousands in the architectural surfacing market.

Then there is my older product - Dichrolam Burls, which are optically identical to Australian Fire Opal, and I used to only make it in glass, but now in thick acrylic but markets are slim for that. Not sure if acrylic would work in knife handles. Maybe other resins - need help there.

I paid my membership as maker so I can post this inquiry. If this has any potential in knife handles let me know. The solid figured CF machines like any other CF, no voids, polishes to high luster - same as any other CF. Planning to mold a panel next week with Kevlar (gold) interleafed within every three layers of CF so when machined you get a zebra-striped effect. Gotta stay tuned to this thread to see that when I post pics.

Thickness are currently about 1/8" to 5/16". Can easily go thicker, or epoxy to standard CF plate. Master panels are 20 x 24 (Solid CF / Kevlar curly), 24 x 48 in Fire Burl, White Burl, Red Burl etc, and 33 x 57 in Quilted figure (resin filled, not solid yet). ChatoyancePanels.JPG

Cool responses - very informative - need to steer my development into the right direction. The dichroic material has always been an acquired taste - great for guitar inlays but maybe not for knives (PRS, Fender CS, Martin, Jens Ritter use it for guitars). But when I molded the CF, then I thought of broader use.
Anyone know of a red colored fiber composite? Looking for other colors other than the yellow of Kevlar. Maybe I will simply dye the Kevlar or add candy to the epoxy.

Samples are available to anyone that wants to try it - just PM me with address.

Kirinite is a funky colorful knife handle material people like to use also. I'd be interested in a sample of the C.F. that looks like curly maple. The brown and black piece.

I would also be interested in trying samples of whatever materials you have. Keep in mind that knife handles are quite a bit smaller than guitar bodies. We would need a fairly tight wave to display well. Think Tiger/Flame/Fiddleback Maple vs. Curly Redwood. The Maple will show a lot of curl per inch while the Redwood (generally speaking) will show only a couple of curls because of the larger scale of the curls.

Additionally, there is a lot of knife handle material out there in "standard sizes" like 1" x 1.5" x 5". For guys like me that make Bowie handles with a bit of drop and flare we could use blocks in the 1.25" x 2.25" x 6" range, as well as sheet stock in the 1/4", 3/8" and 1/2" thicknesses. I would also like to see a product that is designed to be seen from the edge as opposed to the flat sides, for use a spacer material. Any resins you use should be tough and shock resistant.
 
Very unique ideas, message sent :) I think the opal could be very nice in small doses for inlays as well.

This is the type of info I was looking for. I was actually planning too make a mold for wider waves in order to do a thicker build in the 3/8" range. Maybe I'll stick with the current mold, sample it out, then see what y'all think of that first.
Building up thickness beyond 1/4" will likely require simple straight uni block material. Not sure if I can "figure" uni any thicker than 3/8" (cuz I'll need to build 5/8" then machine down to 3/8").
 
This is the motivation I need - thanks a ton guys!!! Very good directions here. Now once my wife starts studying for her payroll class, I'm heading to the shop to cut another mold with waves in all three axis (x,y and z) for forming 1/2" thick CF. Is there such thing as too much chatoyance? Guess I'll find out next week with new layups.
Then my big question is why spend all the extra $ on additional layers of pricey CF just to build thickness. Anyone opposed to using Richlite or off-the-shelf CF blanks in 1/4" +/- as bottom half of a 1/2" or thicker blank if you all want 1" thick material? Top 1/8" to 3/16" is the primary viewing/shaping area anyway.

Then I am thinking of interleaf material. Like copper foil. maybe brass, if I can get the interlaminar adhesion. Not much different than you guys do with laminated steel / damascus. Kindof synergistic.

BTW - I got all your PM's - thanks, and will be laminating all this new thicker stuff monday, machining and polishing tuesday, then shipping Wednesday.

I might even do a micro-quilt pattern. I have molds for geometrically consistant, repeat wave patterns but natural patterns that look like wood figure is best for this product. The dichroic wave pic is only as example of how this molding process came about, so don't assume Im going to mold CF in these patterns, unless requested.

Then thinking of ways to integrate the burls into the CF as inlays / veining inserts. Here are a few pics to continue this brainstorm.
