摘要

Thermoplastic composites have relatively high impact resistance, and are good for the vane of the jet engine that sometimes suffers bird strike damage. Matched-die press molding process is a good process for the vane which has complex airfoil shape. But many laborious test moldings are needed to fix the adequate process parameters. Process monitoring/controlling with in-mold sensor can reduce the number of test moldings. Dielectric properties of PEEK resin in matched-die press molding process are measured. The correlations between melt viscosity, PvT properties and AC conductivity of PEEK are discussed. The inflection point of the temperature-AC conductivity curve agrees with onset of increasing and melt viscosity, and the onset of high shrinkage due to crystallization. The process control diagram utilizing dielectric properties is devised. The laminated CFRP plate is successfully molded by the controlled process. The capability of process monitoring/controlling utilizing the dielectric sensor is confirmed.
