Abstract
There is described a process for manufacturing shaped articles in which a fibrous material is mixed with an adhesive and maintained in a mold under pressure until the adhesive has set, which comprises using as the fibrous material a mixture of an essentially finely fibrous material based on synthetic fiber and of chopped monofilaments which confer the necessary hardness and stiffness on the shaped article to be manufactured, the adhesive content of the ready-produced shaped article being less than 10% by weight, based on the shaped article. The process makes it possible to manufacture shaped articles having a low adhesive content, which are repeatedly recyclable.
