Forming a three=dimensional fibre=reinforced composite preform

摘要

The manufacture a three-dimensional fibre reinforced composite component, especially a vehicle floor, based on a main structure of long fibre layers with local reinforcement in high stress areas. The local reinforcements (6) are stitched to the long fibres layers (4) to form a flat integral fibre preform (2) which is then shaped and consolidated under heat and pressure in a tool to form a three dimensional component.
