Short glass fiber-reinforced (SGFR) thermoplastics are used in many industries manufactured by injection molding which is the most common technique for polymeric parts production. Glass fibers are commonly used as the reinforced material with thermoplastics and injection molding. In this paper, a critical plane-based fatigue damage model is proposed for tension–tension or tension–compression fatigue life prediction of SGFR thermoplastics considering fiber orientation and mean stress effects. Temperature and frequency effects were also included by applying the proposed damage model into a general fatigue model. Model predictions are presented and discussed by comparing with the experimental data from the literature.

This paper aims to investigate the effect of fabrication processes on fatigue life enhancement of interference-fit pin-loaded glass fiber reinforced plastics (GFRP) composites. In this experimental study, three GFRP composite fabrication processes are used: hand lay-up (HL), vacuum infusion (VI), and hybrid (hand lay-up + vacuum infusion) processes. Stainless steel pins with interference fits ranging from 0% to 1% are inserted into the GFRP samples. The quasi-static and fatigue properties of the pin-loaded composites with interference fit (0.6% and 1%) are then compared to samples with transition-fit (0% of interference fit). Even with possible local damage on the joints, interference fit does not degrade the performance of the composite joints under quasi-static loading, especially when kept under 1% of interference fit. However, fatigue life is highly related to the fabrication processes. Vacuum infusion processed GFRP samples show most visible fatigue life improvement due to interference fit, while hand lay-up or hybrid samples have moderate improvement. Fractography and failure mode of each sample are examined using microscopes.
