Mechanical performance of SFRP depends on various factors (fiber fraction, geometry, etc.), among which the fiber orientation is difficult to predetermine, yet it needs to be considered during product design and manufacturing. This is important for parts with complex geometry and varying wall thicknesses, since variations in fiber orientation within the part, if not properly analyzed, may lead to unexpected or premature part failure. In our research, we investigate the effect of fiber orientation on the long-term time-dependent behavior in shear for polyphenylene sulfide with 40 wt% glass fiber reinforcement. Our results show that fiber orientation influences the magnitude of creep compliance (load transfer from matrix to fiber), however, the time-dependency and time-temperature relationship remains the same, regardless of the fiber orientation, suggesting that the composite time-dependency and thermal properties is solely governed by the matrix material.
