Abstract

A fibrous mat for hot moulding to moulded articles is described. This comprises a sandwich laminates formed from a central tangled fibre layer subject to the action of a binder and one heatproof, thermosetting binder-containing tangled fibre surface layer on the two surfaces of the central layer. The surface layer, at least of the unmoulded mat, has a greater tensile strength than the central layer and in the case of the mat moulded to the moulded article is in the form of a moisture-regulating membrane. The weight per unit area of the binder-free portion of the heatproof tangled fibres of the surface layer is 10 to 100 g/m<2> and the individual tangled fibres are coated in fibre-enveloping manner with 100 to 200% by weight, based on said weight per unit area, of a binder already precondensed prior to the moulding of the fibrous mat, in such a way that diameter ratio between the coated and the uncoated tangled fibres of the surface layer is between 1.4 and 1.75.
