“…Thus, the formulation EP-RVF 20-5 has the lowest absorption rate (36.12%), while the formulation EP-RVF 40-15 has the highest absorption rate (71%) compared to EP-RVF 0. The absorption rate of EP-RVF is comparable to the literature on plant fibre-reinforced composites presented in Table 2 [41,[79][80][81][82][83] and could be explained by the fact that RVF is very hydrophilic with an absorption rate between 303% and 662% [21]. This suggests that treatment to reduce the high hydrophilicity of RVF should be consid-ered before introducing it as a composite reinforcement, as suggested by Huisken et al [41].…”

This study evaluates the effects of lengths and reinforcement ratio of Raphia vinifera fibres (RVFs) on the physical and mechanical properties of an epoxy matrix composite. Three volume fractions (20%, 30%, and 40%) and three lengths (5, 10, and 15 mm) of fibres were used to produce the composite, and the samples were subjected to the absolute and apparent density, porosity, water absorption rate, and tensile and flexural strength. The probability of failure of the composite is described by the means of two-factor Weibull model. In addition, a theoretical approach to predict mechanical characteristics based on empirical models was carried out. The results show that the addition of RVF decreases the density of the composite, while the porosity and absorption rate increase. The mechanical test shows that the tensile and flexural stress and Young’s modulus of the composite are lowered compared to those of the resin alone. Multivariate analysis of variance (MANOVA) and Tukey test showed that fibre lengths and reinforcement ratio significantly lower the mechanical properties of the composite. The distribution of strength and Young’s modulus follows Weibull’s law. Furthermore, the Cox–Krenkel mathematical model has the best approximated model for the experimental results after the tensile test. Based on these results, this material could be used as reinforcement parts for vehicle backrests or interior decoration in the construction industry.

“…The tensile modulus gradually increased with an increase in filler loading from 20%wt (1.32 GPa) to 40% wt i.e (1.62 GPa). This observation is in agreement with other researchers [7,8,9,10]. Incorporation of rigid fiber into polymer matrix reduced the matrix mobility, resulting increased in stiffness and higher tensile modulus of the composites.…”

mpact and tensile properties were carried out on Kenaf Powder (K) Polypropylene (PP) reinforced with Kevlar (KV) composites plate prepared in-house using hot press technique. The effect of bonding agent, Maleic Anhydride grafted Polypropylene (MAPP), on the strength and impact toughness was also conducted. The size of kenaf powder used was limited to 100μm. The kenaf/polypropylene composite designated as KPP specimens were tested through tensile test (ASTM D 638) and izod test (ASTM D256) for 20-40% weight ratio of kenaf powder. The optimum weight ratio of KPP sample was selected and then underwent for the drop impact testing. The selected KPP sample was further reinforced with Kevlar cloths. This hybrid composite is designated as KPP/KV sample and further tested in izod impact and drop tests. The impact toughness of KPP reinforced with KV is almost 4-6 times without KV. There are also slight improvements in the impact toughness of the KPP/KV samples with MAPP.

“…Meanwhile the lowest fracture toughness is 0.89 MPa.m 1/2 which belongs to composites filled with 355 µm OPEFB fibers (largest size). The trend of fracture toughness is slightly the same with its tensile strength that was reported in other publication [7]. Comparing the trend of fracture toughness result against the increasing of OPEFB fiber size with their respective izod impact strength that has been published [9] somewhere else, found out that the trend is in contrast.…”

“…This behavior is due to the weak interfacial interaction between matrix and filler, leading to weak interfacial bonding. Besides that, this trend could be due to the non uniform dispersion of bio-fibers within the polymer matrix impairs the mechanical properties [7]. The highest fracture toughness is 1.16 MPa.m 1/2 at 180 µm of OPEFB fiber size (smallest size in this study) due to resistant enough with PP matrix.…”

The effect of oil palm empty fruit bunch (OPEFB) fiber size on the fracture toughness of OPEFB/PP/PPnanoclay composites was investigated. Four fiber sizes ranging from 180 μm, 250 μm, 300 μm, and 355 μm were used to reinforce PP/PPnanoclay composites. The ratio of PP/PPnanoclay was 7:100 by weight (7 phr). Fracture toughness of the composite was determined according to ASTM D5045 and single edge notch bending (SENB) been employed during the test. The result indicates that the fracture toughness of OPEFB/PP/PPnanoclay composites has decreased as OPEFB fiber size increased. Fracture surfaces investigated through the scanning electron microscopy (SEM) showed that the bonding between fiber and matrix for OPEFB/PP/PPnanoclay composites with smaller OPEFB fibre size has better bonding as compared to OPEFB/PP/PPnanoclay composites with larger OPEFB fiber size.
