G10 fiberglass boards are made of a special glass epoxy laminate that has extremely high strength. G10 fiberglass is used in marine applications due to its superior strength, moisture resistance, and excellent electrical and fire insulation.
Fiberglass boards make excellent non-corrosive backing plates for high load deck hardware or bond to engine room bulkheads to hold mounting brackets. G10 boards are sold in 1/4 and 1/2 inch thickness.
G-10 is similar in strength and density to starboard, but because it is formed from epoxy resin, it bonds easily using most two-part epoxies.
Available in Backing Plate sizes and full sheets.

I bought this to plug a hole in the dash of my boat. The previous owner had cut a hole and I needed to fill it. Worked perfectly.

backer plate, plain and simple. I like how you can sand down the sharp edges of it to fit the contour of your application. It also drills easy, but it doesn't flex at all! Great backer plate, although if you're buying only one, the shipping will ding you. I found that a bit ridiculous.

Worked great for my use, replaced the bottom of my fiberglass boat exhaust. I used a jig saw to cut the material when through a lot of blades

I used the G10 board 1/4" thickness to replace the bottom of my wet exhaust muffler. It was perfect. I cut the 12"x12" x1/4" piece into an 11" diameter circle and glassed it in. I cut the material with a jig saw and finished the edges with a belt sander. It is hard and I did go through about 6 blades cutting out my piece. Expensive but worked great for my needs.

I received my 12"x12" x1/4" piece and had to cut an 11" diameter circle out of it. I used a jigsaw. Burned up 12 Bosch jigsaw blades but it cut nice. Use a belt sander to finish it off. Very tough stuff. I'm using it to replace the bottom of my wet exhaust muffler. Nor I just have to glass it in.

Needed to make a frame for bilge vents. Replacement vents are a different width. The frame will be a type of "picture frame" I will fit into place around the existing cut out in the hull. I will recess the frame into the hull and epoxy into place.

I rebuilt the plumbing for my boat holding tank. I used the fiberglass board and PVC pipe instead of bronze plate and copper pipe. Should last my life! Cutting and drilling G10 is like cutting sheet metal. Easy.

Purchased 2 sq feet of 1/4" G10 fiberglass boards to use as thermal insulation between steel parts. The panels were cut into smaller pieces and isolated mating steel parts where mechanically joined. G10 has excellent thermal resistance with 1/4" offering as much as 1" plywood AND unlike wood has excellent compression qualities. The product was packaged better than a Faberge egg. I thought it was as fragile as glass and started to worry that I might have spent good money on an unusable product. Not so, it's tough as nails and machines beautifully. Very happy with product and might be ordering another soon. Highly recommended.
