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.
L'invention concerne une technique de fabrication simplifiée pour former directement une structure de composites modulaires avec au moins une surface relativement plane et au moins un élément sinueux dans un composite modulaire lié de manière interne. Une matrice de matériaux fibreux et/ou autres est déposée dans des couches qui sont formées ultérieurement dans des formes ondulées ou de type ondulation et exposées à une étape d'activation. Au moins un élément est composé d'un matériau contractile qui rétrécit en cas d'activation, comme par chauffage dans un four, pour devenir relativement plat et éventuellement lié à au moins une autre couche non contractile qui reste dans une forme sinueuse après l'étape d'activation.
