Abstract:
Described are Rigid fiber cores such as carbon fiber cores for sandwich composite structures. The carbon fiber cores may be fabricated into various truss configurations including pyramidal lattice truss. The carbon fiber cores may be filled with foams for enhanced mechanical performance.
Abstract:
Composite foam based on expandable microspheres reinforced with fibers is described. Also disclosed are methods of making microsphere foam reinforced with fibers and methods of use thereof. The disclosure provides foam that performs equally and better than the performance of most thermoplastic foams commercially available.
Abstract:
Disclosed are compositions of short fiber reinforced phenolic foams, methods of making and using the same. The disclosed fiber-reinforced phenolic foams have a seven-fold increase in peel resistance over the unreinforced counterpart foam. The phenolic foam has enhanced fracture toughness without sacrificing the critical fire retardant properties.
