G10 FR4 300x335x1.5MM Epoxy Fiberglass Composite Sheet Panel,0.5~10MM Available

I used this for a backing plate for sailboat cleats, and it was very tough and durable. I would buy this again.

I bought this thicker 8mm plate for an auxilliary fence on a miter saw because I thought some extra thickness might be needed for rigidity. This G10 black is very dense as expected (heavy) and very rigid. I probably could have used 6mm and been fine even with recesses for mounting screw heads.I've worked a lot with cutting and sanding all types of phenolic sheet and the standard green/tan G10 material as well as carbon fiber plate. I expected this to be hard on tools and difficult to work with after primary cuts but it really worked like a breeze, just as easy as any phenolic. You will get some fiberglass itchies if you aren't careful but the cut edges on the material itself are clean and without any fuzzing or chipping. This was true for me with an aluminum cutting circular saw blade (-5° TCG) as well as a little carbide grit abrasive wheel on the DeWalt 3" cutoff tool - it even routed extremely clean with roundover bits and a flush trim bit. A decent HSS Freud forstner bit did four shallow holes/recesses and didn't seem any worse for the wear but I was expecting it to be trashed. This is definitely more abrasive and harder on tools than other plain plastics and resin composites but not as bad as carbon or as bad as I expected it to be.I think the black might have some graphite in it but I'm not sure. The chips/flakes were light and flexible just like what comes off of nylon and some plastics. The saw/sanding dust was just very fine powder like phenolics.Do wear eye and breathing protection because these particles can be quite dangerous if you work with it much, and skin protection is highly advised unless you like the itchies.Good stuff and I will buy this again. I wish they had some other precut options like strips/bars. By the way, all edges were very flat and smooth, all corners darn close to perfect 90°, sharp crisp edges...nice.

Excellent product, repeat customer.

I bought this to use as a print surface. As others have recommended, I thoroughly cleaned and wet sanded the entire surface. I don’t know if I can say that it is better than other surfaces (PEI, PEO, etc.) but since my printer already has the magnetic sheet, it’s a little thicker than a spring steel plate and it has to be clipped/clamped down. The bed mesh was considerably different than the stock plate. I also need to either recover the bed alignment screws when switching to this since I haven’t attempted to cut out the notches yet.

Great for knife scale liners.

Pretty decent, works fine as a build plate on a printer. the thickness keeps it from warping up much under shrinking abs/nylon prints. It is a little soft compared to my natural colored fr4, a bit easier to dent, and if your first layer height is low it will mark a bit where the print was. Has held up well to use with TAP probing though. Adhesion was an issue at first even with a sanding, scrubbing at it with an alcohol soaked microfiber until it came back clean fixed that, and has been fine since with just a quick wipe before a print. Overall satisfied.

I needed some G10 material to build a “Tac Table” to hold optics on top of my tripod. This stuff was priced competitively and comes in a variety of thicknesses and sizes. Machining it, and drilling it was a breeze and there were no loose fibers or delamination. Excellent quality material that I’ll buy again to keep in the shop for future products.

Used as a 3d printer bed. Kind of interesting to cut with only a razer blade, but it worked! Not sure if this is quality stuff of not, but I have extra.
