“…This parameter can increase the scattering and deviation of replicate results (Shah et al 2012b). Notably, the values reported in the present study were higher in terms of strength and modulus compared with previous studies that used chemically treated and untreated, UD and random mat kenaf/glass hybrid composites (Ya'acob et al 2011;Ghani et al 2012;Atiqah et al 2014).…”

“…It has recently been estimated that substituting natural fibers for 50% of the glass fibers used in automotive applications in the USA would eliminate 3.07 million tons of carbon dioxide emissions and 1.19 million m 3 of crude oil consumption by 2020 (Davoodi et al 2010). Natural fibers such as hemp, jute, sisal, and kenaf are lighter, low-cost materials with highly specific mechanical properties that can reduce the density of a composite by 10 to 15% compared Recently, Atiqah et al (2014) developed chopped strand mat (treated and untreated) kenaf-glass fiber-reinforced unsaturated polyester hybrid composites fabricated using a sheet molding compound process for structural applications. In this study, the fiber volume was kept at 30%, and the kenaf to glass volume ratio was changed.…”

The objectives of this work were to investigate the effect of kenaf fiber alignment on the mechanical and fatigue properties of kenaf/glass hybrid sandwich composites. Three types of kenaf fibers were used, namely, non-woven random mat, unidirectional twisted yarn, and plain-woven kenaf. A symmetric sandwich configuration was constructed with glass as the shell and kenaf as the core with a constant kenaf/glass weight ratio of 30/70% and a volume fraction of 35%. Tensile, compression, flexural, and fully reversed fatigue tests were conducted, and a morphological study of the tensile failure surface of each hybrid composite was carried out. The non-woven mat kenaf hybrid had poor properties for all tests, while the unidirectional kenaf hybrid composite possessed higher tensile strength and similar compressive properties compared with the woven kenaf. Hybridization with kenaf fibers improved the fatigue degradation coefficient of the final composites to 6.2% and 6.4% for woven and unidirectional kenaf, respectively, compared with 7.9% for non-woven. Because woven kenaf hybrid composite is lightweight, environment friendly, and has a considerable balance in static and fatigue strengths with low fatigue sensitivity in bidirectional planes compared to glass, it is strongly recommended for structural applications.

“…Investigations of the proper fibre treatments for hybrid composites are common in literature [96,157,[160][161][162][163]. These treatments mainly improve the performance of the natural fibre layers on its own, and do not show synergistic effects.…”

Fibre-reinforced composites are rapidly gaining market share in structural applications, but further growth is limited by their lack of toughness. Fibre hybridisation is a promising strategy to toughen composite materials. By combining two or more fibre types, these hybrid composites offer a better balance in mechanical properties than non-hybrid composites. Predicting their mechanical properties is challenging due to the synergistic effects between both fibres. This review aims to explain basic mechanisms of these hybrid effects and describes the state-of-the-art models to predict them. An overview of the tensile, flexural, impact and fatigue properties of hybrid composites is presented to aid in optimal design of hybrid composites. Finally, some current trends in fibre hybridisation, such as pseudoductility, are described.

“…There are various bast fibers as reinforcement is used by various researchers for making polymer composites like jute, kenaf, hemp, grewia optiva etc [6][7][8][9]. The polymer composites reinforced with bast fibres are reasonable strong, economical, light in weight, less hazardous and have a potential to be used as structural materials.…”

Abstract:In the past few decades, natural fibres have shown remarkable achievements in the field of reinforced polymer composites because of environmental issues and petroleum crises. Biodegradable fibres (bast, animals hair, stalk, seed etc.) has been used by researchers because of its low cost, low density, abundant in nature, high stiffness etc. over other man-made fibers. The majority of plant fibers which are being considered as reinforcement materials for polymer composites are bast fibers (the outer cell layers of various plants) such as hemp, jute, kenaf, grewia optiva etc. Among these fibers Grewia optiva is recently explored fiber and is presently being assessed as reinforcement in polymeric composites. In this paper, we have discussed and reviewed the extraction process of Grewia optiva fibers and various surface treatments such as graft copolymerization, mercerization, Benzoylation and silane methods for enhancement of the surface adhesion properties of Grewia optiva fibres with their matrice and the effects of these surface treatments on mechanical properties of such fabricated composites.
