In recent years, short glass fiber reinforced PA66 composites (GF/PA) have been considered to be certain significant to promote the development of “automotive lightweight”. At current study, the mechanical properties of injection molded GF/PA were investigated both in axial and off-axis directions. In addition, the fiber volume fraction (vf ) and the residual length as well as the distribution of glass fiber (GF) after injection molding were investigated particularly to evaluate the interfacial property based on SEM observation and Kelly-Tyson model equation. It is found that the composites have a trend with a slight increase in the critical fiber length and decreased interfacial shear strength with an increase of vf.
