FIBRE MATRIX AND A METHOD OF MAKING A FIBRE MATRIX |
摘要 |
A method of forming a three dimensional fibre structure is disclosed which comprises the steps of a) providing a starting material which comprises liquid carrier, fibres and binder; b) passing the starting material over a substrate so as to deposit fibres onto the substrate; c) forming a three dimensional fibre matrix; and d) curing the binder. The flow of material onto the substrate may be controlled such that the flow of a starting material over the substrate is chaotic and fibres are laid down in a three dimensional structure containing a high proportion of voids. The preform may be pressurised while moist and is cured under pressure. The fibres may comprise carbon fibres; recycled carbon fibre has been found to be particularly useful. The resulting preform may be stochastic and is suitable for use in ablative and braking applications.
