Abstract
Process for manufacturing reinforced moulded polyester to make moulded articles. The process is applied to the manufacture of plates or sheets of a polyester sandwich of the type known commercially as SMC (Sheet Moulding Compound) based on a mixture of unsaturated polyester with boosters and different additives, which is reinforced with fibreglass to mould diverse articles. Additives are considered to be catalytic systems, self-extinguishing and self-moulding additives etc. as well as the addition of solid particles of recycled material composed of a mixture of the indicated solid and the corresponding fibreglass.< IMAGE >The sheet moulding cpd. of sandwich type board or 'blanket' is based on a mixt. of unsatd. polyester resin with fillers and various additives, reinforced with glass fibres. Additives include catalyst system, self-extinguishing and mould release cpds. together with particles of the recycled moulding cpd.
