The pre-dipped material of thermoplastic composites is prepared by using conmingled yarns with reinforced fibers and thermoplastic fibers, and it offers a cost-effective manufacture method of thermoplastic composites reinforced with continuous fibers. The recent researches in theory modelling and experimentation regarding thermoplastic composites made from commingled yarns are reviewed thoroughly. The theory models of resin impregnating into fibers bundle along the direction perpendicular to the axis of fiber bundle are summaried and discussed. The experiments about the influence of various fiber bundles and processing parameters on composites behaviors are introduced. The exist weaknesses with theory and experimental researches in this field are pointed out.
