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.
