“…This mechanism was due to matrix strength higher than interlaminar stress, in addition the fibers have smaller strain to failure compare with matrix. This similar reported by Roslan et al [30]. Finally, the compaction zone occurred at the last stage when the load reached 2.414 KN due to crushed material densification and has no more material to be crush.…”

The interest in the using of natural composite has been increased significantly in recent years in many engineering fields due to their distinctive characteristics; these as low weights, high-energy dissipation ability, and it's considered ecofriendly. In this paper, an experimental investigation is done on the effect of structure geometry on the crashworthiness characteristics of woven jute mat/epoxy composite specimens. The main objective is to understand the influence of the geometrical shape, and layers numbers on the energy absorption of composite specimens under uniaxial quasi-static loading. The twelve hollow specimens were manufactured by combination of manual lay-up and vacuum bladder moulding technique using bi-directional natural jute mat (with two and three layers) and epoxy resin, each with 50mm inner diameter and 100mm length. Three different cross-sectional shapes were used; the hexagonal, octagonal, and decagonal of specimens. From the current unique experiment, it was exhibited most of the composite samples demonstrated stable and progressive deformation with acceptable repeatability during the test process. It also showed that the deformation characteristics and the energy absorption of the octagonal cross-section shape are better than the other cross-section shapes such as hexagonal and decagonal cross-sections shapes. Furthermore, the three laminated layers contributed to high specific energy absorption (SE) and better crushing efficiency (ɳc) for each profile. Overall, the octagonal pattern configuration with three plies can be considered as optimal for crashworthiness of structure application compared to other composite samples.

“…Through morphology, the agglomeration and surface characteristics were identified. Findings by previous researchers had found that the agglomeration caused failure in tensile since the high loading of filler influenced the agglomeration had caused the adhesion between filler and matrix to decrease, thus, causing crack propagation point [6,[17][18][19].…”

The effect of fabrication methods on polysiloxane (POS) composites were studied by analysing both method of casting (CA) and compression (CO). The POS composites were reinforced with 2-12 wt% of natural derived silica from rice husk (RHA SiO2) as a filler which incinerated at 700°C. The composites behaviour were analysed through tensile testing (ASTM D412). Through comparison study on both CA and CO composites’s tensile behaviour it shows that both composites strength keep increasing with 2wt% - 10wt% RHA SiO2 addition but strength decreased at 12wt% due to agglomeration of RHA SiO2. Moreover, it was found that the tensile strength of CO composites had offer 23.56% higher compared to CA composites. The difference were influenced by the distribution of RHA SiO2 as filler. The surface morphology of CO composites had showed that the most of RHA SiO2 were embedded and less agglomeration, compared to CA composites that had lots of agglomeration which lead to higher tendency of crack propagation. The arrangement of filler due to the CO method that helps RHA SiO2 to distributed homogenously and embedded in a matrix of POS to avoid agglomeration and lead better adhesion respectively. Thus, CO method had potential to offer in enhancing tensile behaviour compared to CA method by influencing filler distribution arrangement for vibration absorber application.

“…32 Composite structures made with braided fiber preforms have also shown a lot of success in the field of crashworthiness, particularly in the form of braided composite tubes. 23,[33][34][35][36][37][38] The continuous fiber bundles in a braided fabric ensures that all fibers can sustain loads resulting in excellent mechanical properties, and that complex three-dimensional shapes can be formed as reported in literature. 33,34 Braiding has also been applied to produce braided composite rods consisting of axial fibers wrapped by braiding fiber bundles.…”

This article presents an experimental study on the quasi-static crushing performance of carbon fiber reinforced polymer (CFRP) rods consisting of unidirectional carbon fibers wrapped by braided glass fibers. Rods with and without a taper are tested and then inserted in extruded and expanded polystyrene foam and cardboard panels. Hybrid columnar aluminum tube–CFRP rod structures are also tested in all panel materials. These results are compared to those based on glass fiber reinforced polymer (GFRP) rods, GFRP rods in polystyrene foams, and to GFRP rods in cardboard from a previous study. Tapered CFRP rods exhibit progressive crushing behavior with specific energy absorption superior to GFRP rods, with values of 82 kJ/kg and 65 kJ/kg, respectively. Moreover, the highest specific energy absorption (111 kJ/kg) is obtained in hybrid columnar aluminum tube–CFRP tapered rods, exceeding values of aluminum tubes (89 kJ/kg) and equivalent structures containing GFRP rods (102 kJ/kg). Within panels, cardboard produces the largest increase in mean load of CFRP and GFRP rods due to most constraining fiber splaying during crushing, followed by extruded foam, and lastly expanded foam. However, crushing displacement is most restricted in cardboard due to earlier final compaction. The smallest variations in crushing load occur in extruded polystyrene due to greater homogeneity throughout the foam structure.
