Abstract
A sheet-like sandwich molding having two outer rigid covering layers and, as the core, at least one sheet-like structure of fiber material, which has been deformed by deep-drawing and been provided with synthetic resin. The sheet-like structure of fiber material, constituting the core, can, for example, be a knitted fabric provided with a curable condensation resin.
Claims8
A core material comprising at least one textile woven or loop fabric of fiber material in the form of a sheet, the textile fabric having deformations therein formed by a deep-drawing process to thereby prestress the fiber material so deformed, the deformations having surrounding side walls, cured synthetic resin impregnating the fiber material, and openings between the resin impregnated fiber material extending over the stressed side walls of the deformations formed during the deep-drawing process.
