“…reinforced with natural and synthetic fibers. Basrani et al 13 investigated the influence of strain rate on a composite reinforced with four different natural fibers in addition to top and bottom layer of glass fibers. It was found that for strain rates ranging from 0.00022 s −1 to 0.0888 s −1 , the tensile strength of the composite increased by 8% with the increase of the deformation rate.…”

Thermoplastic composite materials are being increasingly used in many domains, such as automotive, marine and aeronautics. This growing interest is due to the relatively good mechanical properties and the recycle-ability of these materials. In various heat assisted forming technologies, thermoplastic composites may be subjected to severe conditions such as high temperatures, complex strain paths and potentially significant strain rates. This is expected to highly influence the overall behavior of these materials and make the characterization of their mechanical behavior more complicated. In this paper, the mechanical behavior of discontinuous glass fiber reinforced polypropylene composite is investigated at temperatures going from room temperature (RT) to 120°C and strain rates ranging from quasi-static conditions to 10 s−1 by means of uniaxial tensile tests. The effect of material orientation is also investigated at RT and quasi-static strain rate of 0.001 s−1 pointing out a clear anisotropic behavior. The tensile properties including Young’s modulus E, ultimate tensile strength σ ult and strain at failure ɛ f are determined based on the Standard ISO-527 reporting an obvious sensitivity of the material to temperature and strain rate. Based on literature review, the phenomenological isotropic constitutive model of G’Sell and Jonas, originally designed for unreinforced semi-crystalline polymers, is selected to describe the mechanical behavior of the studied material. A modification of the original constitutive equation is proposed for a better representation of the overall behavior of the material at different temperature and strain rate conditions. Finally, the validity of this phenomenological law calibrated by means of the uniaxial tests, is evaluated for an equi-biaxial loading state close to that encountered by the material during heat assisted sheet forming process. The significant disagreement highlighted between numerical and experimental results proved that the uniaxial tensile tests are not sufficient to characterize the behavior of the material when a complex loading condition is imposed.

“…Additionally, at high strain rates, the tensile strength and tensile modulus of the composites increased. Basrani et al [20,21] performed the tensile test on hybrid GFRP and hemp-UHMWPE composite at different strain rates using a servo hydraulic machine to study the strain rate effect. They found that tensile strength has been enhanced by 8.21% for hybrid GFRP and 56.46% for the hybrid hemp-UHMWPE as the strain rate increases.…”

The aim of this study is to examine the stress–strain behavior of Glass Fibre Reinforced Polymer (GFRP) composite with three different orientations, namely [0°/90°]s, [±45]s, [0°/+45°/−45°/90°]T. To achieve this, the GFRP was simulated using the Split Hopkinson Bar (SHPB) setup in ABAQUS/CAE. The striker bar was used at three different velocities (9.7 m s−1, 12.7 m s−1, and 14.3 m s−1) to produce strain rates ranging from 1000 s−1 to 2000 s−1. The dynamic response of the GFRP composite was studied by considering its stress–strain behavior. The effect of strain rate on the elastic modulus and energy absorption capacity of GFRP laminates was analyzed through complete stress versus strain curves. The results showed that the elastic modulus and energy absorption capacity of GFRP laminates were sensitive to strain rates, with an increase in strain rate leading to an increase in the elastic modulus and energy absorption capacity.

Natural fiber and its hybrid composites have a promising future due to their economic, lightweight, environmentally superior, and sustainable properties. The purpose of this research is to explore the morphological and physical properties of composites made of hemp-epoxy and ultra-high molecular weight polyethylene-hemp-epoxy. The compression moulding technique is used to fabricate the UHMWPE -hemp hybrid composite and hemp-epoxy sample at a different orientation. These samples are subjected to different types of mechanical testing, including flexural, impact, hardness, and tensile tests at different strain rates as per ASTM standards. The result indicates that the flexural strength, impact strength, and hardness of the hybrid composite are more than the hemp composite. Scanning electron microscopy has been used to examine fractography at various strain rates. It is found that with the increase in the strain rate, tensile strength increases. It is observed that there is an increase of more than 56.49% in the specimen’s strength with the addition of 8.3% ultrahigh molecular weight polyethene fiber reinforcement.
