Abstract

1418091 Fibre-reinforced mouldings NATIONAL RESEARCH DEVELOPMENT CORP 22 April 1974 [27 Feb 1973] 9537/73 Heading B5A Fibre-reinforced mouldings are produced by applying simultaneously to the same surface region of a mould a spray of matrix material and two or more sprays of fibre lengths. The spray heads are preferably individually controllable by adjustment of the inclination of the spray heads to the mould surface, the included angle of the spray at the spray heads, the distance between the mould and spray heads, the velocity of fibres leaving the spray heads, the length of fibres, or by changing the type of fibre. In a preferred arrangement, the fibres in the first spray are low modulus fibres, e.g. glassfibres or other organic polymer fibres, e.g. polypropylene or nylon, a second spray of matrix material is inclined more steeply to the mould surface than the first spray and a third spray of fibres, e.g. carbon, glass or other ceramic such as alumina or zirconia or titania, mullite or wollastonite, is inclined less steeply than the first. The matrix material may be cement, gypsum, clay, resin or other particulate material, sprayed as a slurry or as a liquid.
