“…In contrast, Wirawan et al [71] reported the density of the sugarcane bagasse reinforced poly (vinyl chloride) is decrease by increasing the fibre loading. The low density of NFRPC has resulted in this material being preferred across the world, especially in the automotive and building industries [72,73]. Recent studies mentioned that the density of NFRPC is between 1.1 and 1.6 g/cm 3 [74,75].…”

Material selection has become a critical part of design for engineers, due to availability of diverse choice of materials that have similar properties and meet the product design specification. Implementation of statistical analysis alone makes it difficult to identify the ideal composition of the final composite. An integrated approach between statistical model and micromechanical model is desired. In this paper, resultant natural fibre and polymer matrix from previous study is used to estimate the mechanical properties such as density, Young's modulus and tensile strength. Four levels of fibre loading are used to compare the optimum natural fibre reinforced polymer composite (NFRPC). The result from this analytical approach revealed that kenaf/polystyrene (PS) with 40% fibre loading is the ideal composite in automotive component application. It was found that the ideal composite score is 1.156 g/cm 3 , 24.2 GPa and 413.4 MPa for density, Young's modulus and tensile strength, respectively. A suggestion to increase the properties on Young's modulus are also presented. This work proves that the statistical model is well incorporated with the analytical approach to choose the correct composite to use in automotive application.

“…2a displays the plastic behavior of AA6060. Furthermore, mechanical properties of the polyurethane foam were taken as Young's modulus E=8.5GPa, Yield stress σy=1.24MPa, Density ρ=174kg/m 3 (Rezvani and Jahan, 2015). Meanwhile, stress-strain curve of the polyurethane foam, obtained from the uniaxial compression test according to the ASTMD 1621-94 standard, has been given in Fig.…”

This paper aims to explore crashworthiness performance of new designed foamfilled tapered structures under axial and oblique impact load conditions. The structures consisted of inner and outer tapered tubes connected together by four stiffening plates. They also included square, hexagonal, octagonal, decagonal and circular cross-sectional shapes with different ratios of a/b (ratio of the inner tube side length to the outer tube one). The ratio of a/b was assumed to be 0, 0.25, 0.5, 0.75 and 1. Crashworthiness criteria of specific energy absorption (SEA), peak collapse force (Fmax) and crash force efficiency (CFE) were obtained for these structures using the experimentally validated model in LS-DYNA. Based on the numerical results, semi-foam filled structures (i.e. those with the ratio of a/b=0.5) demonstrated greater crashworthiness performance than foam filled single-cell ones. Furthermore, according to the TOPSIS calculations, cross sectional shape of decagonal was found to be an outstanding potential profile for the automobile structural components.

“…Analisa teoritik dikaji oleh Nghia et al (Nghia, et al, 2013;Nghia, et al, 2014) dengan memprediksi kirteria crashworthiness pada tabung persegi dan mempunyai 1 lubang crush initiator untuk setiap sisi spesimen yang terletak di tengah dari kedua ujung spesimen. Selain dari itu Rezvani et al (Rezvani & Jahan, 2015) juga melakukan optimasi desain dari multikriteria crashworthiness mengenai pengaruh intiator dengan menggunakan variabel jumlah annular rings terhadap spesimen silinder yang diisi oleh polyurethane foam. Optimasi dilakuakn dengan mengggunakan metode Vikor.…”
