METHOD AND APPARATUS FOR Z-DIRECTION REINFORCEMENT OF COMPOSITE LAMINATES
摘要
A method and apparatus for Z-direction reinforcement of composite laminates is disclosed. Discrete fibers (25) are pulled through a fiber composite preform (11) in the Z-direction by needles (27) having bars (29) thereon to insert the Z-direction reinforcement (31) into the composite preform (11) from a discrete fiber mat (23) having discrete fibers (25) therein.
