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 composite structure with at least one relatively flat surface and at least one sinuous element in an internally-bonded unitized composite is provided. A matrix of fibrous and or other materials is deposited in layers which are subsequently formed into corrugated or wave-like shapes and exposed to an activation step. At least one element is composed of a contractive material which shrinks 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 remains in a sinuous shape after the activation step.
