“…At 300 s -1 , the shear modulus increased by 21.7 %, while shear strength rose by 59.6 %, when compared with their quasi-static values. The increase of shear strength and modulus are in good agreement with reported results in the literature [44][45][46][47] for in-plane shear properties measured with ± 45° tensile tests. Similar observations can be found in the literature for other off-axis tensile test campaigns [31,[48][49][50][51].…”

“…The conversion of plastic work to heat caused local adiabatic heating in the polymer matrix, but the rapid nature of impact events did not allow enough time for heat to dissipate [42][43][44]. Lienhard et al [25,45] also found that there was a local adiabatic temperature rise in the polymer matrix at high strain rates, and the increase of the local adiabatic temperature rise would be more obvious with the higher the strain rates [42]. Therefore, the white sphere might be a droplet formed by the melting of the PP matrix due to local overheating.…”

Long glass fiber reinforced thermoplastic composites have been increasingly used in automotive parts due to their excellent mechanical properties and recyclability. However, the effects of strain rates on the mechanical properties and failure mechanisms of long glass fiber reinforced polypropylene composites (LGFRPPs) have not been studied systematically. In this study, the effects of strain rates (from 0.001 s−1 to 400 s−1) on the mechanical properties and failure mechanism of LGFRPPs were investigated. The results showed that ultimate strength and fracture strain of the LGFRPPs increased obviously, whereas the stiffness remained essentially unchanged with the strain rates from low to high. The micro-failure modes mainly consisted of fibers pulled out, fiber breakage, interfacial debonding, matrix cracking, and ductile to brittle (ductile pulling of fibrils/micro-fibrils) fracture behavior of the matrix. As the strain rates increased, the interfacial bonding properties of LGFRPPs increased, resulting in a gradual increase of fiber breakage at the fracture surface of the specimen and the gradual decrease of pull-out. In this process, more failure energy was absorbed, thus, the ultimate strength and fracture strain of LGFRPPs were improved.

“…Research performed on various materials ranging from polymers, metals and composites have proven the rate dependency of these materials. [1,2,[5][6][7][8][9][10] Most of the studies available on HSR response of composite materials are for thermoset-based composites such as E-glass/vinylester, [11] glass/epoxy, [12,13] carbon/epoxy, [14][15][16] and Kevlar/epoxy. [17,18] These studies reported the influence of fiber orientation, stitching of fibers and sizing of fibers on the HSR response of composites.…”

An investigation of the effect of strain rate on the dynamic compressive behavior of glass/polytetrafluoroethylene (PTFE) composite is presented. Experimental studies were carried out on two dimensional (2D), satin weave (SW) and three dimensional (3D) woven glass/PTFE composites using split Hopkinson pressure bar (SHPB) apparatus. Commercial grades of glass/PTFE fabrics were autoclaved to prepare the composite laminates and circular specimens were cut out using a high-pressure water jet. High strain rate studies confirmed the rate-dependent behavior of all the woven composite systems under consideration. The highest rates of loading were attained by 3D woven specimens for identical incident energies. The highest peak stress attained by 3D woven specimens was 501 MPa, which was trailed by 2D woven specimens with 482 MPa stress. The advantage of satin weave was not reflected in the small specimens as the peak stress attained for identical loading was limited to 405 MPa. Similarly, the highest strain and toughness were recorded for 3D woven composites. However, the SW pattern unlocked a new possibility of controlling the primary damage axis. Furthermore, an analytical method is presented based on variable rate power law to predict the dynamic compressive stress of glass/PTFE.
