Abstract
The invention relates to a method for producing a semi-finished product for producing a composite molded part (), in particular a composite fiber molded part, wherein a higher-melting reinforcement material (), in particular higher-melting reinforcement fibers are combined with lower-melting fibers () made of thermoplastic into a laminate (), wherein the lower-melting fibers are spun and after spinning are combined at a fiber temperature Twith the higher-melting reinforcement material, in particular with higher-melting reinforcement fibers, into the laminate forming the semi-finished product. The fiber temperature Tlies in a temperature range between a temperature of 25° C. below the heat distortion temperature Tto 55° C. above the heat distortion temperature Tof the thermoplastic of the lower-melting fibers.
