“…Jute fibers are more dispersed in the resin than untreated fabrics reinforced composites. This is because the hot-alkali treatment removed pectin, wax and other impurities on jute fibers surfaces, and increased the surface roughness and effective surface areas of the fibers [35,36,37]. Also, the removal of lignin and hemicellulose, achieved by the treatment, improved the crystallinity of the cellulose.…”

In this study, jute fabrics/epoxy-laminated composites were fabricated via a simple and effective manual layering. Hot-alkali treatment was used to pretreat jute fabrics to improve their interfacial compatibility. The effects of hot-alkali treatment with five concentrations (2%, 4%, 6%, 8% and 10%) on the composition, crystallinity and surface morphology of jute fibers, were analyzed with the aids of Fourier transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD), and the scanning electron microscope (SEM). The mechanical properties (tensile and flexural) of laminated composites, and the morphology of the tensile fracture surface, were analyzed. The results indicated that the crystallinity index (CI) and crystallite size (CS) of the cellulose in jute fibers were improved, and there were three stages for CI and CS with the increase of alkali concentrations. Hot-alkali treatment improved the mechanical properties of laminated composites, especially for the 6% NaOH-treated jute fabric reinforced. The tensile strength, flexural strength, tensile modulus and flexural modulus of 6% NaOH-treated fabrics reinforced composites were enhanced by 37.5%, 72.3%, 23.2% and 72.2%, respectively, as compared with those of untreated fabrics reinforced composites. The fiber pull-out and the gaps of the tensile fracture surface were reduced after hot-alkali treatment.

“…These are illustrated in Figure 5. The process parameters were chosen on the basis of findings seen in literatures [7,8,24,25] . Before taking up the stamp forming process, each circular blank was pre-heated to the definite blank temperature in the oven and then transferred to the steel die.…”

“…In the case of hemispherical forming, the formability could be determined by considering the maximum extent of possible deformation allowed by the blank. The forming ratio has a significant contribution in the composite sheet forming process [7,26] . The draw depth of GFRTP stamp formed component, as illustrated in Figure 7, was measured using a Coordinate measuring machine and was converted into the forming ratio using Equation 1.…”

“…Nurul Fazita et al [7] studied the impact of parameters on the existence of deformations in fabric reinforced poly-lactic-acid polymer composites and identified that the hot tooling conditions would provide better-quality domes. They observed the larger significance of wrinkles in the wrap direction of the composite domes in contrast with the weft direction.…”

Advanced fabric reinforced polymer composites find extensive applications in aerospace and structural fields due to their high mechanical properties. A novel stamp forming technique finds extensive use in the hemispherical forming of thermoplastic composites. This study investigates the influence of stamp forming parameters on the formability of thermoplastic composite using Taguchi's robust design and grey relational analysis. Taguchi's orthogonal array was used for designing the forming experiments. Responses such as forming ratio and logarithmic thickness strain were considered for the assessment of sheet formability through single and multi-response optimization. Analysis of variance was used for the determination of the contribution of each parameter on formability and it was identified that the die temperature acts as a prominent factor, followed by blank holder force and blank temperature. The confirmation test was conducted at optimum parameter levels and the obtained experimental grade was seen within the confidence interval of the predicted value.

“…Bamboo can be used as reinforcement material of composite in various forms, such as bamboo powder [27], bamboo strips [28][29][30], bamboo fibres [31,32], bamboo fabrics [33] and bamboo woven mat [34]. Figure 2 shows an example of a laminate composite consisted of epoxy resin as the matrix and bamboo woven mat as the filler.…”

The use of bamboo fiber in reinforced concrete beam to reduce crack AIP Conference Proceedings 1887, 020003 (2017) Abstract. The hydrophilic character is a major concern in the development of natural fibre reinforced-polymer composites. As hydrophilic material which easily absorbs water, the water content inside bamboo fibres should be carefully controlled to produce bamboo composite possessing acceptable mechanical properties. The bamboo fibres provide a reservoir of water which diffuses into the interfacial region of epoxy matrix. Different hydrophilicity between bamboo fibres and the polymer matrix affects the fibre matrix adhesion which in turn influences the physical and mechanical performances of the composites. This article provides a short review on the current progress of bamboo-based polymer composite development. Further this present review discusses several treatments for bamboo fibres in order to improve the fibre-matrix adhesion and the effects on the moisture sensitivity mechanical performance of resulted composites. Those treatments aim not only to change the hydrophilic character of bamboo fibre but also to bring about the hydrophobic properties to the fibres. It is expected that the potential of bamboo material could be fully exploited as an alternative natural fibre reinforced material for polymer-based composites in wider application.
