“…Fajrin and co-workers [ 41 ] experimentally studied jute fibre–epoxy composites prepared by vacuum bagging process using Iosipescu shear testing (also in-plane shear); the jute fibre were provided in woven configurations. They reported a shear strength of 25.5 MPa and diagonal fractures known as off-axis failure mode.…”

Natural fibres have been partly substituting synthetic fibres in polymer composites due to their renewable character and many other advantages, and sometimes, they can be hybridized into a single composite for a better combination of properties. This work aims to study the effect of hybridization and stacking sequence on the mechanical and physical properties of the glass/jute laminates. For that, pure jute, pure glass and glass/jute hybrids were manufactured by vacuum infusion process using orthophthalic polyester resin. The composites were characterized via C-scan analysis, density, volume fraction of constituents and optical microscopy analyses. Mechanical properties were obtained from tensile, compression and shear tests. The longitudinal properties were higher than transverse properties for all laminates. The hybrids presented intermediate density and mechanical properties compared to pure glass and pure jute laminates. The hybrids produced similar density and tensile modulus, but with small differences in tensile strength and compressive strength which were justified based on variations in resin and void content due to the influence of the stacking sequence (glass/jute interlayer regions). In addition, the pure glass and the hybrid laminates displayed acceptable failure morphology in the in-plane shear test, but not the pure jute laminate.

“…Figure 15 is shear failure mode and cracking pattern of chemically treated sisal fiber-reinforced concrete. Many researchers have been trying to study the shear strength of natural fibers using the V-notch (Iosipescu shear test) with the guidelines of ASTM standard D5379M [46]. From normal concrete (control mix), SFRC achieved higher shear strength with parallel trend lines.…”

The incorporation of sisal fiber into the concrete matrix reduces waste disposal, which has negative environmental impacts. The aim of this study was to perform an experimental investigation on shear strength and microstructure of chemically treated sisal fiber-reinforced concrete (SFRC). In order to accomplish the aim of the study, physical, shear, and mechanical properties of concrete reinforced with chemically treated sisal fiber have been performed. 0.50%, 1.00%, 1.25%, 1.50%, 1.75%, and 2.00% of sodium hydroxide (NaOH) and sulfuric acid (H2SO4) treated sisal fiber were used as an addition to the dry weight average with the help of the American Concrete Institute (ACI) mix design procedure. After the 7th and 28th days of curing, shear strength according to the ASTM D5379M standard and the mechanical properties of concrete have been conducted. For microstructural properties, scanning electron microscopy (SEM) and X-ray diffraction (XRD) were conducted after the concrete was cured for 28 days. Forty-six percent and 20% compressive strength enhancement at the 7th and 28th days of curing was compared to the control mix. Twenty-seven percent enhancement was recorded in the split tensile strength of 1.5% SFRC as compared to the control mix at 28 curing days. A shear strength of 1.5% SFRC was improved by 95% at the 7th curing days and 28% at the 28th curing days as compared to the control mix. As compared to conventional concrete, SFRC shows a denser microstructure. In addition to this, portlandite, quartz, calcium aluminum silicate, and C─S─H crystal are the available phases in the concrete matrix.

“…An interfacial shear test was performed on jute/graphene composites by Sarker et al 65 and the strength obtained was 14.00 MPa, about 245% higher than the untreated jute fibres, which possessed a value of 4.16 MPa. Fajrin and Sari 103 studied the shear properties of jute and hemp fibre composites using the V-notch shear test and determined their strengths to be an average of 25.57 and 22.46 MPa, respectively. An interfacial shear test was also conducted on Noil hemp fibres by Etaati et al 70 and the value was found to increase to a maximum of 13.60 MPa when 5% of MAPP is added to a composite with 30% Noil hemp fibre content.…”

Natural fibre composites are ideal material substitutes for combating the issues of pollution and non-biodegradability. Several industries, the automobile industry, in particular, have shown tremendous inclination towards the usage of natural fibre composites in their deliverables. Besides providing a wide array of useful properties, natural fibre composites have offered flexibility in terms of choosing various combinations of fibres and resins. Owing to this, this paper aims to collect data and categorize the natural fibre composites based on the types of treatments and properties they exhibit. Characterization was done by taking into consideration chemical and enzymatic treatments as well as tests such as the tensile, flexural, compressive, impact, shear and hardness. Based on the values obtained from the characterization, the paper suggests suitable and feasible natural fibre composites as biocompatible replacements to conventionally used materials in the automotive industry.
