“…Furthermore, Azrin Hani et al [8] in her study of hybrid (woven coir/kevlar) composites explores the potential of coconut coir to resist high speed impact penetration by reducing the amount of synthetic fibre used in composites. On the other hand, as reported in Ude et al [9], woven natural silk/epoxy/foam was seen as better energy absorber where the results displayed better load bearing capability qualities. Literature in hand reveals that no single group of researchers has completely characterised the mechanical properties of woven coir and woven kenaf for 10 m/s (meter per second) impact penetration and flexural strength.…”

Natural fibre has become the subject of interest for research and development by various organizations due to its biodegradable and competitive mechanical properties. However most of the researchers are focusing on random orientation and compressed mat with only little researches concerned with woven or textile structure. This research work involved with mechanical analysis of woven natural fibres composite specifically coir and kenaf natural fibres. Plain woven coir and kenaf were produced from their yarns using self designed weaving device. The woven fibres were then converted as reinforcement in composite. Woven composite was prepared using manual hand lay up technique couple with vacuum bagging. Impact penetration and flexural (three point bending) test were conducted on composite sample. Morphological analysis was performed using Scanning Electron Microscope (SEM). From the results obtained, dry woven coir composite displayed better mechanical properties for both impact and flexural properties compared to kenaf composite. Warp direction of coir composite and kenaf composite showed a better flexural strength compared to weft composite direction. Coir yarn with slight lower fineness value than kenaf yarn had contributed to the higher fibre density in woven structure. The structure used as composite reinforcement in turn produced better mechanical properties.

“…The tensile strength of PCL-woven composite is higher than those of PCL-knitted and PCL-nonwoven materials due to a large amount of straight geometry fibres present in the woven fabric [26]. Some researchers fabricated stacking of silk fabric layers for the preparation of composite using epoxy resin [27–31], whereas the present study focuses on the stacking of silk fabric with biodegradable PCL.…”

In this work, the stacking of different layers of silk fabric reinforced polycaprolactone biocomposites were prepared by compression moulding technique. The mechanical and biodegradation behaviour were investigated. The mechanical properties of the different layers of silk/polycaprolactone composite were observed. The 14 layers of silk/polycaprolactone composites showed higher mechanical properties when compared to other composites. This was due to its sufficient mechanical interlocking between the fabric and the matrix. Further, scanning electron microscopy analysis confirmed the good interfacial bonding between silk and polycaprolactone. The in-vitro degradation study revealed that silk/polycaprolactone composite uptakes more water due to hydrophilic nature of silk while polycaprolactone showed higher amount of weight loss. Though there was a decrease in trend in the tensile properties of composite, still they can be used as a biodegradable plate due to its adequate mechanical strength. The changes in pH of the composite were also noticed and found negligible. Thus, the biodegradable silk/polycaprolactone composites are a promising alternative implant for patients, as they provide temporary mechanical support and controlled rate of biodegradation for the bone plate application.

“…50,51 In low velocity impact response of plain woven silk/epoxy composites, it was revealed that with the increase in number of plies load bearing capacity and energy absorption capacity of the composite was increased but delamination and area of damage were increased. 52 Woven hemp/epoxy composites showed comparable low velocity impact and cyclic fatigue response with the glass/epoxy composites. 53…”

Improvement in mechanical properties of natural fiber reinforced polymeric composites remain a key focus of researchers in the recent years. However, few studies have been carried out for the improvement in low velocity impact properties of such composites. In the present article, the results on the effect of weave structure of reinforcing fabric and addition of glass microsphere fillers (GMS) on the drop weight impact properties of Hemp/Green epoxy composite samples are reported for the first time. Hemp woven fabrics having four different weave structures (matt, satin, hybrid weave A and hybrid weave B) were developed in an inhouse lab. Four layered composites containing glass microspheres (0%, 2%, 3.5% and 5% on the weight of resin) were fabricated using vacuum bag molding. Drop weight impact testing was performed at 10 J impact energy, and force-displacement, force-time and energy absorbed-time behaviors were recorded and analyzed. The results were statistically analyzed as well. It was found that both weave design and glass microspheres show a significant effect on impact properties of the developed composites. The composite sample reinforced with satin woven reinforcement exhibited maximum value of impact force, whereas composite samples containing 5% glass microspheres display more resilience and stiffness as compared to other structures.
