WAVE-LIKE STRUCTURES BONDED TO FLAT SURFACES IN UNITIZED COMPOSITES AND METHODS FOR MAKING SAME

摘要

A simplified manufacturing technique to directly form a unitized composit e structure with at least one relatively flat surface and at least one sinuo us element in an internally-bonded unitized composite is provided. A matrix of fibrous and or other materials is deposited in layers which are subsequen tly formed into corrugated or wave-like shapes and exposed to an activation step. At least one element is composed of a contractive material which shrin ks when activated, such as by heating in an oven, to become relatively flat and optionally bonded to at least one other non-contractive layer which rema ins in a sinuous shape after the activation step.
