    摘要： A method and apparatus are disclosed for making preforms from a fibrous material such as glass fibers. The apparatus includes a porous mold form that, in carrying out the method, is attached over the open face of a charge box. The charge box and mold form are then rotated as a single unit to dump glass fibers or other fiberous reinforcement held in the charge box onto the mold form. Air is drawn through the porous mold form to thereby retain a layer of the glass fibers against the mold form. The mold form and charge box are rotated back to their initial position and then disconnected. A binder is sprayed onto the glass fibers if not otherwise already applied thereto. The binder is then cured, resulting in a unitary glass fibers preform.

    摘要： 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.
