Determining the resistance to abrasion of the flexible cladding for armours and automobile structural components with the aid of lab scale tests has become increasingly important. In the present study, three body wear behaviour of flexible green composites comprising of jute in woven fabric form with interleaved natural rubber sheets bonded through rubberized B stage cured Pre pegs have been studied. Flexible composites are fabricated in three different configurations having different layers of jute and rubber. The present study makes use of silica sand as the abrasive medium. The specific wear rate along with loss in mass and volume of the composite due to wear is determined and it was found that specific wear rate is dependant of the sliding distance. Comparing the specific wear rate of all the three stacking sequences, it was found that JRJ stacking sequence provides better wear resistance. Compliant and tough nature of the rubber makes it hard to wear it out through tearing action and also the wear resistance of flexible composites is enhanced with inclusion of rubber. Mechanism of wear in each of the constituent used is studied. The present study serves as a benchmark work for the future research in this area.

“…Jute is a lignocellulose fibre having promising mechanical and thermal properties. Its light-weight, less cost and ease of availability made it ideal to use it as reinforcement, using these type of natural fib re material as reinforcement is eco-friendly way of dealing the natural fibre [26][27][28], whereas SiC are ceramic particles used in order to increase the hardness of the composite.…”

An experimental analysis of tensile, hardness and wear properties of aluminium metal matrix composite through stir casting process

Among several methods to fabricate Aluminium metal matrix composites, stir-casting technique is used for large-scale production due to its being less expensive. This research is concerned with the fabrication of Aluminium composites with SiC and Jute Ash Particles, for sake of producing a cost-effective composite with enhanced properties. Wear behaviour was studied using pin on disc tribometer and it was found that wear resistance increases with-addition of reinforcement particles. Fabricated composite samples showed almost 4 times better wear resistance compared to base material. Matrix metal reinforced with SiC showed the best wear resistance of all fabricated samples. Coefficient of friction significantly decreased with the presence of reinforcement due to formation of mechanical mixed layer. Tensile Strength was escalated with the introduction of reinforcement as load is transferred to strongly bonded reinforcement particles. Microhardness was enhanced with the introduction of reinforcement and Sample 2 with SiC as reinforcement showed the best microhardness. Microstructure and fractography of the base metal and fabricated composites was analyzed by Scanning Electron Microscope (SEM).

“…12 Here, it was to be emphasized that the existence of high compatibility and good adhesion between components led the formed composites to exhibit better mechanical performance compared to both partly miscible and immiscible polymer matrices. 13,14 In other words, the formation of relatively stronger and effective intermolecular attraction forces (Van der Waals forces) between the component polymer chains in the matrix provides both the additional endurance and relatively larger withstanding capability against the deformation to the polymeric materials, 15 which results in the reinforcement of the polymer composites. Furthermore, the various chemical methods like silane and alkaline treatments, acetylation, and bleaching were also used in order to get rid of this compatibility problem coming out in the polymer matrices.…”

This present study centers sensitively on the determination of the effect of natural turkey feather fibers (TFFs) loading on fundamental features (thermal, mechanical, water-uptake, and micro-structural) of thermoplastic polyurethane (TPU). The composites with different TFFs contents (3, 6, 9, and 12 wt.%) were fabricated by the melt blending method using the twin screw extruder and micro-injection molder. The samples were characterized by means of differential scanning calorimeter (DSC), universal mechanical (tensile and hardness) tester, water-uptake, and scanning electron microscope (SEM) techniques. The thermal analysis depicted that the melting temperatures of the soft and hard segments as well as the crystallinity degree of TPU increased consistently with the increase of TFFs loading level thanks to the formation of better close-packed TPU chains in the matrices. As for the mechanical test results, when compared neat TPU, the tensile strengths were reinforced by 26.8% and 19.7%, and the modulus increased by 6.6% and 45.1% for the composite samples including 3% and 6% of TFFs, respectively. However, drastic diminishment were observed at further contents. Additionally, TFFs loadings brought about gradual increase in the water-uptake capacities of the composites due to the increasing of the number of voids and omnipresent flaws in TPU matrices. The taken SEM images also revealed that, at low contents, there existed the enrichment of interfacial adhesion between TFFs and TPU matrix, whereas the morphological appearance of the composites get worse at high contents accompanied by the formation of micro-structural defects.
