ABSTRACT:
A method of impregnating a fibrous textile material with a plastic resin so as to produce an impregnated fibrous textile material which can be laminated under heat and pressure to produce a composite article. Such method comprises forming a dispersion of a powdered plastic resin in water which has been thickened by means of a water-soluble thickener; applying the dispersion to a fibrous textile material to distribute the resin over the fibers thereof; drying the fibrous textile material treated in this manner to remove the water present; and heating the dried material at a temperature sufficiently elevated to cause the resin to fuse and form a matrix for the fibers.
