Abstract The mechanical properties of wollastonite‐filled phenolphthalein poly‐(ether ketone) (PEK‐C) composites have been studied at room temperature and 200°C. The dispersion of wollastonite particles in PEK‐C matrix were investigated by means of scanning electron microscope. The modulus and strength of the composites increased with filler content. The reinforced effect of wollastonite on PEK‐C is more marked at elevated temperature. The glass transition temperature of the composites is higher than that of PEK‐C and is independent of filler content. The restriction effect of filler particles on the molecular mobility of the polymer matrix should be attributed to the reinforcement. © 1997 John Wiley & Sons, Inc. J Appl Polym 65: 649–653, 1997
