“…A decrease in both these properties is observed with the addition of leather particles. A similar trend has been reported by other researchers [21,22] and is attributed to the softness of leather particles. It is noteworthy that the difference in the standard deviation of the failure strength of epoxy and its composite has reduced (figure 5(c)) [23].…”

Strategies are suggested for the waste utilization of industrial leather by preparing composites with epoxy and high-density polyethylene (HDPE). The addition of leather improves the average specific compression toughness of epoxy by 29%. The fracture surface analysis suggests the incorporation of leather microparticles leads to a transition of failure mode of epoxy from brittle to ductile. In addition, the dynamic strength of the leather/epoxy composite is found to be 69% higher than that of neat epoxy. However, no significant changes are observed when HDPE is infiltrated with leather. Apart from dispersing the leather particles directly in polymer, a novel strategy is presented here in which leather/HDPE microfibers are prepared and then used to reinforce the epoxy matrix. The specific compression modulus of this composite blend is 8% and 65% higher than epoxy and HDPE, respectively. Fractography is further carried out on the failed specimens to understand the failure mechanism in each composite. A change in the failure mode is observed when epoxy is reinforced either with leather particles or the microfiber. While the failure strength of the microfiber is found to be higher than epoxy, the strength of microfiber/epoxy interface is lower than that of epoxy.

This paper studied the effects of fiber length and fiber content on the physical, mechanical and water absorption behavior of coir fiber-reinforced epoxy composites. Twenty different samples were prepared by varying the fiber length (3 mm, 6 mm, 9 mm, 12 mm and 15 mm) and fiber content (5 wt%, 10 wt%, 15 wt% and 20 wt%) using the hand lay-up technique. The density, hardness, tensile strength, tensile modulus, flexural strength, impact energy, compressive strength, compressive modulus, inter-laminar shear strength, fracture toughness and percentage of water absorption of the composites were analyzed. The experimental investigation reveals that the void content and percent of water absorption increases with increase in fiber length and fiber content. The result shows that the density of composites increases with increase in fiber content, while a decrease in density is observed with increase in fiber length. Similarly, the tensile strength, compressive strength, inter-laminar shear strength, flexural strength, and impact strength show their maximum values at 12 mm fiber length and 15 wt% of fiber content. The hardness and tensile modulus, on the other hand, increase with increase in fiber length and fiber content. Morphological analysis is also carried out to observe the fiber pull-out and fracture behavior of the composites using scanning electron microscope.

“…The primary advantages of using natural fillers in thermoplastics can be listed as low densities, low cost, nonabrasive nature possibility of high filling levels, low energy consumption, high specific properties, biodegradability, availability of a wide variety of fibers throughout the world, and generation of a rural/agricultural-based economy [2]. Natural fibers are subdivided based on their origins, into four types: seed hairs (cotton, kapok), bast-fibers (flax, hemp, jute, and ramie), leaf-fibers (sisal, henequen, coir, and abaca) and wood flour (wheat husk, rice husk) [3]. Hybrid composites are materials made by combining two or more different types of fibers in a common matrix.…”

The main objectives of this research were to study the effect of water absorption on mechanical properties of hybrid fiber reinforcement for polypropylene composites. The poor resistance towards water absorption is one of the draw- backs of natural fibers. Hybrid filler-polypropylene composites are subjected to water immersion tests in order to study the effects of water absorption on the mechanical properties. Composites specimens containing 30 phr and 40 phr fiber weight were prepared by melt blending process. Water absorption tests were conducted by immersion specimens in distilled water at room temperature for different time durations (24, 48, 72, 96, 120, 144, 168, 192 hours). The tensile, flexural and impact properties were investigated before and after water absorption. The percentage of moisture uptake increased as the increasing order of the filler loading due to the high cellulose content. The phase morphology of wood flour/wheat husk polypropylene hybrid composites were investigated by SEM, the dynamic mechanical properties of the composite are analyzed by DMA & wheat, wood filler interaction are analyzed by FT-IR
