Abstract

Weft-inserted warp-knitting can be applied to produce textile composite preforms comprising both reinforcement fibers and thermoplastic matrix ribbons at comparatively low cost. A newly developed technique (denoted QUIKTEMP) for fast processing of molded parts is presented. As a special feature, the concept allows for the material staying with one mold throughout the process, while the cycle time is still short. Hence, pressure can be applied continuously and without additional cost due to prolonged cycle times.
