Abstract
A method for forming a composite part involves forming a layup comprising (a) preforms/flat form-factor feedstock, either of which includes a plurality of fibers and a matrix precursor, and (b) a differential-melt polymer. The matrix precursor and the differential-melt polymer differ as to at least one of thermal properties and rheological properties. The layup is subjected to controlled application of heat and pressure to melt the matrix precursor and differential-melt polymer. The polymers are then cooled to form a composite part that displays properties attributable to all the constituents. As a function of a variety of factors, the resulting part can be homogenous or heterogenous, and the properties can be localized or global throughout the part.
