<p>Fiber reinforced thermoplastics sheet is produced by a wet method from (a) an aqueous dispersion of reinforcing fibers and dispersing agent; and (b) an aqueous dispersion of thermoplastics polymer powder and an ionic polymer additive of opposite charge to the fiber dispersion. The dispersions are mixed, a high molecular weight ionic polymer flocculating agent is added, of charge opposite to that of the mixture, and the resulting suspension is drained and dried to form the sheet.</p> |
