Abstract
Hybrid and commingled yarns containing reinforcing fibers and thermoplastic matrix fibers when sized with a dispersion or emulsion having a dispersed phase containing a thermoplastic compatible with the thermoplastic of the matrix fibers but having a lower melting point allow preparation of thermoplastic matrix fiber reinforced composite structures at reduced consolidation temperatures, cycle times, and/or consolidation pressures without loss of composite physical properties.
