Abstract

Abstract: For high quality manufacturing of thermoplastic composites, the CF/PEEK placement platform based on fiber laser heating was designed and built. And the composite laminates were prepared. Then based on the equipment parameters of the placement platform (laser power, placement speed, placement pressure), the experimental analysis of univariate parameters and multivariate orthogonal parameters were performed. Meanwhile, the interlaminar shear strength (ILSS) was measured and the micromorphology was observed. The influence of process parameters of temperature and pressure on the mechanical properties of CF/PEEK laminate was investigated. The experimental results show that ILSS first increases and then decreases with increasing temperature and pressure within the experimental range. The influences of two process parameters(temperature and pressure) on the ILSS of laminates are different and the effect of the placement temperature is greater than the placement pressure during the manufacturing process. The optimal process parameters for preparation of CF/PEEK laminatesin the experiment are placement pressure of 0.2 MPa, placement temperature of 402.6 ℃.
