Abstract
The present invention provides plastic-based fiber-reinforced honeycomb, and a process for its preparation. The fiber-reinforced honeycomb has high temperature durability yet can be fabricated and handled by simple techniques. Honeycomb structures in accordance with this invention have the strength, impact resistance and processing characteristics of thermoplastic materials and yet offer high temperature resistance and solvent resistance characteristics which permit such processing steps as the application of multiple coatings for purposes of density adjustment and enhancement of mechanical properties.
