Abstract

Composite panels having glass fibre reinforced resin layers cladding core panels or blocks of different material, where the core layer is assembled from a series of relatively narrow profiles which fit side by side, each of which is surrounded on all but one face by a layer of resin impregnated fibrous sheet which undulates continuously across and between the core profiles. The panels are used for mfr. of building panels, boat hulls, vehicle bodies etc., esp. where curved structures must be developed. Each facing layer can bond strongly to the areas of the compatible undulating layer which is exposed across the top of alternate core elements. The core elements are positively enclosed and bound even if there is relatively poor adhesion between the core material and the resin impregnating the covers and/or the undulating layer.
