Abstract
A process for providing batches of a mouldable, fibre-reinforced thermoplastic material matched to a moulding to be produced and accompanied by heating, whereby a free-flowing initial product of fibers and thermoplastic material-containing binders is heated as a strand and a matched batch is separated from the strand and supplied to batch further processing.
Claims7
Process for producing dimensionally stable semi-finished products of fiber-reinforced thermoplastic material, the process comprising the steps of converting a pourable initial product made of heat-resistant fibers and binder containing thermoplastic material to an endless strand by compression, heating to above the melting point of the thermoplastic material only in a thin jacket area and, after cooling, producing a dimensionally stable finished product with a solid outer jacket and constant cross-section.
