The technology for opening tow was applied to the opening of reinforcing fiber tow for thermoplastic composites. The effect of its opening on the impregrnation behaviors of matrix resin was investigated in comparison with those for unopened tow through experiments and theoretical calculations. On-line measurement of void volume change during compression molding for carbon fiber/nylon 6 composite was carried out. Micro-scopic observation on the cross-section of parts fabricated at several molding time and measurement of transverse bending strength bof these parts were alsoconducted. Based on the theoretical model presented previously, the void volume changes for several molding conditions were simulated under a certain assumptive void pressure-change. All these results show consistently that the tow opening makes the impregnation of matrix resin into the reinforcing fiber much easier.
