  • Carbon fibre panels with laser formed holes
    Patent number: 5741456
    Abstract: A layer 1 is formed from carbon fibre strands that are pre-impregnated with epoxy resin to hold the fibers together. The strands of carbon fiber that make up the layer 1 comprise eight uni-directional sub layers that are assembled with their strands extending at different angles to each other. The assembled sub-layers that are impregnated with epoxy resin are then baked under pressure in an autoclave to form a composite layer 1. A laser is then used to burn through the layer to make the holes 2.
