Abstract

Abstract: In order to realize the fabrication of thermoplastic composite lattice structure based on the automated fiber placement and in-situ consolidation process, by taking the meso-scale thermoplastic composite laminate as a representative structure, aiming to improve its mechanical properties, this paper studies the meso-scale automated fiber placement and in-situ consolidation process through the experiment. Using interlaminar shear strength (ILSS) and micro morphology as characterization methods, the effect of automated placement and in-situ consolidation process parameters on the laminar mechanical properties were analyzed by a single factor experiments and response surface experiments, also a prediction model between parameters and mechanical properties was established. The results show that the influence of various processing parameters on ILSS in the test range was as follows: placement speed, placement pressure, placement temperature. And the interaction effects between the parameters were significant. The ILSS of specimen showed a trend of first increasing and then decreasing with the increase of placement pressure and temperature, and a trend of decreasing with the increase of placement speed. The optimal combination of process parameters in the test range was obtained, that is, placement pressure 14 N, placement temperature 408 ℃ and placement speed 60 mm/min.
