A method for forming a uniformly mixed fibrous mat which comprises feeding a continuous high tensile modulus reinforcing fibrous material and a pre-cut thermoplastic fibrous material with a lower melting point or softening point than the temperature at which the reinforcing fibrous material melts or is damaged to a rotating rotor which is provided with projections to thereby cut the continuous fibrous material and pluck the pre-cut fibrous material, dispersing the thus treated fibrous materials into an air flow to mix the same and thereafter collecting the resulting mixed materials on a net to yield the mat. The product can thereafter optionally be compressed under heat to melt only the thermoplastic fibrous material to thereby consolidate the mat.
