摘要： A resin infusion method that incorporates a melt-on-demand approach. The method includes: (a) providing a curable resin composition in the form of a block of frozen resin (20); (b) coupling the block of frozen resin (20) to an inlet port of a heated extruder (22), which comprises at least one rotating screw (24) housed within a heated barrel (25); (c) progressively melting the block of frozen resin (20) at the inlet port and concurrently feeding the melt resin through the heated barrel (25) to produce a liquid resin having a viscosity suitable for resin infusion; (d) continuously feeding the liquid resin exiting from the extruder to a mold, which contains a fibrous preform; and (e) introducing the liquid resin into the fibrous preform, wherein the block of frozen resin (20) provides an amount of resin composition sufficient for infusing the entire fibrous preform.

摘要： A prepared mold tool having a thermoplastic surface layer polymer coating on the mold surface of the mold tool or prepared prepreg having a thermoplastic surface layer polymer coating on the surface of the thermoplastic fiber reinforced prepreg are described that enhance first ply laydown of thermoplastic fiber reinforced composite prepregs onto mold tools for prepreg forming or in situ tape placement. Resulting thermoplastic fiber reinforced composite parts from a thermoplastic fiber reinforced thermoplastic composite material having structural reinforcement fibers with one or more high performance polymers, and a thermoplastic surface layer polymer coating which forms a polymer blend with the high performance polymers of the thermoplastic fiber reinforced composite material thereby imparting improved properties, and methods for making and using same, are provided herein.
