[QUOTE="ejg, post: 2347102, member: 12381"] It varies, for a hunting rifle we try to have the compound very tough. Load the resin hardener mix with say 1/3 carbon fibre 0.2mm, 1/3 aluminium powder, 1/3 Talc. This mix is easy to machine as well. Dry powders well before use. Aero grade laminating resin with at least 40 min pot life. If one knows that the rifles are being used in extreme warm areas or being shot hot we use a hardener that get's post cure heat treatment at higher temperatures. We use this type on most competition rifles. BTW, post cure before releasing the action from the stock. All goes into an oven. edi [/QUOTE]
