Description: The polymer melt impregnation of glass fibre tapes or rovings is of vital importance for manufacturing textile reinforced thermoplastic composites. In the present paper, the polymer melt impregnation of fibre bundles in injection moulding process is investigated by a specific pull-out test which allows the preparation of the investigated specimen near to process. Several glass fibre roving types with varying appearance and yarn count were placed as a tape insert in a mould for thermoplastic injection process and were impregnated with the injected poly-propylene melt. The fibre bundle pull-out test then was used to determine the quality of melt impregnation which could be verified by magnified photomicrograph. A clear relationship between maximal load in pull-out test and impregnated fibre fraction has been observed. Also a strong influence of the fibre bundle geometry and yarn count on impregnation quality was detected.
