In an effort to show the influence of the hybridization method in hybrid fabric reinforced composites within the characteristic of the fracture and the mechanical properties, two laminate reinforced with bi-directional woven were developed, where one of them was reinforced with a hybrid strand (hybrid strand composite laminate) and the other with a different strands (hybrid fabric composite laminate). Both laminates used polyester resin, Kevlar-49 and glass-E fibers, had four layers and were prepared industrially by hand lay-up manufacturing. The percentages by weight of fiberglass and Kevlar in each type of woven are equal. The hybrid strand composite laminate showed a higher tensile strength, however the hybrid fabric composite laminate showed superior properties in three-point bending test, for example, 41.7 % superiority in flexural strength. The results showed that the hybridization method in hybrid reinforced composites influences the mechanical behavior of laminates and the formation and spread of damage.

“…Specifically, strain rate of up to 860 s À1 , 705 s À1 , 544 s À1 , 840 s À1 and 1149 s À1 has been reported by Harding [14], Gama et al [15], Hosur et al [17], Song et al [16] and Haque and Ali [5], respectively. In our recent studies on high strain rate behavior of woven fabric E-glass/epoxy composites under compressive loading [31][32][33], strain rate of up to 1997 s À1 and 2890 s À1 has been obtained along warp/fill and thickness directions, respectively. In actual practical cases, especially for impact analysis, strain rate could be very high.…”

“…There are typical studies on split Hopkinson pressure bar testing technique [22][23][24][25][26][27][28][29][30]. In some of our recent studies on WF composites [31][32][33] and epoxy resin [34,35], the strain rate was up to 2000 s À1 . Wang et al [36] presented an analytical method for assessing strain rate sensitivity of unidirectional composite laminates.…”

The effect of loading rates and particle geometry on compressive properties of polypropylene/zinc oxide nanocomposites: Experimental and numerical prediction

Compressive properties, of particulate filled polymer matrix composites, are affected (to a certain extent) by the geometry of the particles, as well as the loadingrates. Therefore, this article presents the results on the compressive properties of polypropylene/zinc oxide nanocomposites across strain rates from 10−2 to 10−3 s−1. The specimens were tested using a Universal Testing Machine for static loading and a conventional Split Hopkinson Pressure Bar apparatus for dynamic loading. Results show that the yield stress and 2.5% flow stress, of both PP/ZnO nanocomposites, showed a positive increment with increasing strain rates. However, the yield strain shows a contradictory pattern, where it decreased with increasing strain rates. PP/ZnO‐white seal recorded higher strain rate sensitivity, dissipation energy, stiffness, and strength properties, than that of PP/ZnO‐pharmaceutical, over a wide range of strain rates investigated. Interestingly, the Eyring theory almost agreed with the experimental results. Overall, based on the experimental and numerical results, we do believe that particle geometry, as well as strain rates, has a significant influence on the compressive properties of polypropylene/zinc oxide nanocomposites specimens.
