In the present work an attempt has been made to investigate the bearing strength of the TiO2 and ZnS filled glass fabric reinforced polymer matrix composites (GFRP). The volume fractions in the matrix were chosen as 1, 2 and 3%. Single-hole-pin-loaded specimens of each composite material were tested in tension. The result showed that the bearing strength of the glass fabric reinforced polymer matrix composites joints is associated with the filler content and the geometrical parameters. The increase of the filler content in the matrix has increased the bearing strength of the composites. The height bearing strength was obtained in case of composites with 2 volume% of filler content, and it was found that ZnS filled composites bears more load than the TiO2 filled composites.
