  • METHOD OF PROCESSING A COMPOSITE MATERIAL
    Publication number: 20100086765
    Abstract: A method of processing a composite material comprising heating a porous layer in contact with the composite material above its melting point whereby it melts and becomes incorporated into the composite material. The material may be formed by a matrix diffusion process. In this case the porous layer acts as a distribution layer. Alternatively the material may be formed as a stack of prepregs. In this case the porous layer acts as a breather layer. The porous layer may comprise a polysulphone or polyethersulphone which increases the toughness of the material.
