In this research, a complete systematic technique for fabricating and characterising the various properties of Cochlospermum Gossypium (CG) and oil palm mesocarp fibre (OPMF) reinforced composites are reported. Following the hand lay-up method for manufacturing composites with varying OPMF weight percentages (5, 10, and 15), the composites were subjected to a variety of characterisation tests. To improve the interfacial bonding, capabilities of OPM fibre surfaces were treated with sodium hydroxide (NaOH). Microstructural studies, such as scanning electron microscopy, were performed on the produced samples, followed by mechanical characteristics like tensile, flexural, and impact tests. Furthermore, the TGA (thermogravimetric analysis) test was performed as part of the thermal tests. The treated composites were found to be increased by 69.64% in tensile strength and 38.37% in flexural strength when compared with untreated composites and neat matrix in the tensile test. Thermal study revealed that 15% of fibre content outperforms the other weight fractions of the composites under investigation, as evidenced by TGA, microstructural, and mechanical testing.

The potentials of natural fibre encourage researchers to shift their interest from synthetic fibre. Numerous works have been done on the effective use of several natural fibres in manufacturing composites for automotive and structural applications. In the current investigation, effort has been made to evaluate the effect of the addition of glass fibre and influence of stacking sequence on mechanical properties of kenaf-/glass-reinforced hybrid composite laminates. Hybrid laminates with five different stacking sequences were fabricated by using hand layup technique. After curing, the fabricated composite laminates were cut to the dimension as per ASTM standard. Different tests have been carried out to determine tensile strength, flexural strength, and micro-hardness of fabricated laminates. Based on the findings, a sharp increase in mechanical properties is observed due to addition of glass fibre. Laminate with four layers of kenaf fibre shows minimum values of tensile strength, flexural strength and micro-hardness values. On subsequent addition of glass layer to the laminates, an increase in tensile strength from 35.78 to 166.38 MPa, flexural strength from 42.91 MPa to 155.83 MPa and micro-hardness value from 11.51 to 20.84 HV are reflected. To validate the experimental findings, numerical analysis has been made by using ANSYS R19.0 software. On comparison of experimental and numerical values, the deviation of the result is limited to 3%–12%. The morphology of fracture surfaces is also studied by using scanning electron microscope.

Using natural fibers in structural applications is the subject of much research in the scientific world. Natural fibers are bio-sourced, biodegradable, have a low carbon footprint, and have interesting mechanical properties. The lightness, tensile strength, and elongation before break make natural fibers suitable candidates to replace synthetic fibers. Sometimes, natural fibers must undergo heavy chemical treatment for the extraction of microfiber. This is not the case in this paper, which presents a first attempt to use esparto fiber in its raw state without heavy treatment without soda and bleach. In this paper, the raw esparto stem cut into short fibers is treated, then prepared and used as reinforcement in mortar. The mechanical properties of the esparto stems were identified, analyzed, and improved. The mechanical tests showed a weak adhesion between the mortar and Alfa. Also, excessive absorption of water by the stem induced a delay in the mortar's setting. Even with unsaturated stems, this phenomenon is observable. An improvement was applied to the natural Alfa stem to improve its adhesion and reduce the absorption of spillage water. For the first time, as a major innovation in natural fibers used for cementitious composites, a method is presented in this paper allowing the use of Alfa (esparto) fiber in a mortar while keeping the mechanical strength properties of the mortar. Test specimens 4x4x16 cm were made and reinforced with short fibers of 2 and 3 cm with different volume concentrations: 1%, 2%, and 5%. The flexural strength and compressive strength were determined experimentally. The results show that for the 1% concentration of short fibers of 3cm, the compressive strength is 26 MPa, which is almost identical to the strength of the control specimen equal to 26.03 MPa. Flexural strength of the improved fibers concentrated at 1%, 2%, and 5% reach nearly 4.75 MPa very close to the flexural strength of the control specimen, which is 5.57 MPa. The flexural strength doesn't decrease with treated Alfa fiber concentration increase: this is a unique case in which flexural strength doesn't decrease compared to other natural fibers results in the literature. In a conclusion, Alfa-treated short fibers can be used in secondary structural applications subject to compressive and light bending forces, for example, paving applications.
