Description
Carbon Fiber Tooling Board 1″/25.4mm made from all aerospace 3k 2×2 twill prepreg. These panels use over 100 layers of a toughened prepreg resin system that is great for impact resistance. These panels were cured at 275° F under vacuum and could be post cured additionally up to 350° F if you needed a higher temp rating. There are fine tracer yarns in the prepreg on every ft mark made from nylon and or aramid. They are barely noticeable as they are very fine but are there. These panels are better suited for general purpose applications as well as being machined down into parts. The prepreg in these panels was from an aerospace program that had strict time restrictions for using it. It is past the usable date in those programs however the epoxy still was tested and flowed well enough to make great general purpose panels that properly wet out. There are a few small pinholes in the surface of the panels but overall panels are nearly void free. We have tried to show in photos the panels and the cross section when cutting.
These panels are produced right here in our shop. Due to slight variances in material, we give these tooling boards a range of /- .030 inches in thickness. These panels are typically cut by waterjet. However, due to time constraints they may be saw cut. Therefore, these panels are given a dimensional tolerance of /- .125 of an inch.
