PAPERMAKING COMPOSITION CONTAINING THERMOPLASTICS RESIN AND REINFORCING FIBRES AND PROCESS

摘要

Manufacture of a three-dimensional article from an aqueous suspension comprising at least one thermoplastic resin and reinforcing fibres, comprising the following stages: …a) the components of the suspension are moulded by a wet route in a mould (1) into a preform (7) having the general outlines of the final article in the three dimensions; …b) the preform (7) is then at least partially rid of its water; …c) the preform is then preheated to a temperature above the melting point of the thermoplastic resin; …d) the preform (7) is then moulded under pressure into its final shape in a press (10) heated to a temperature below the melting point of the thermoplastic resin. ……
