The morphological and mechanical characterization of UHMWPE based composite: an experimental study

Abstract

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.

Decision making approaches for recognizing the optimal alkalized corchorus olitorius powder based composites for sustainable applications

“…When reinforced into polymer matrices, these natural fibers generate composites with good mechanical characteristics, minimal weight, recyclability, and biodegradability. The features of natural fibers, such as good strength and stiffness, availability, and low cost, have increased their demand in industries such as automobiles, medicine, construction, and electronics [3][4][5][6][7][8].…”

Effect of strain rate on glass fiber reinforced polymer composite using split hopkinson pressure bar

“…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.…”
