CONTINUOUS MANUFACTURING AND PERFORMANCE OF 3D REINFORCED SANDWICH STRUCTURES

摘要

The patented Napco~® technology presented in this paper is designed to create in a continuous way 3D tailored sandwich structures while maintaining the production efficiency. The through-thickness reinforcement is obtained from regular fabrics. This process allows the production of complex preforms that can be post formed and impregnated with liquid resin using a closed molding production method or thermoformed in the case of thermoplastic composites.
