Abstract

1443732 Moulding fibre reinforced polyurethane foam articles SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 3 Aug 1973 36945/73 Heading B5A A method of producing a fibre reinforced polyurethane foam article comprises forming a fleecy layer of non-woven fibrous material on a support, and applying to the outer surface of the layer a liquid polyurethane foamable composition which sets before the composition has completely penetrated the fibrous layer. The method may be used to produce pipes having an internal resin free fibrous surface and an outer foam layer by wrapping the fleece around a mandrel and spraying the polyurethane composition on to the fleece whilst rotating the mandrel. Alternatively a plate having fibrous layers on both sides may be produced by injecting the foamable composition in between two supported fibrous layers. Suitable fibres are polypropylene, polyethylene or glass.
