“…The average temperature for AH and combined treatments (WSH and ASH) were significantly improved at 50 wt.% compared to 30 wt.%, but the changes for UH and WH were statistically insignificant. Ahmed et al [ 31 ] also demonstrated that fiber modification by grafting of silane coupling agents can improve the thermal stability of the composites. Moreover, the ignition temperatures of UH and WH composites at both fiber compositions were identical, which might be attributed to the lack of a major difference in the fiber cell wall content.…”

The effects of surface pretreatment (water and alkali) and modification with silane on moisture sorption, water resistance, and reaction to fire of hemp fiber reinforced polylactic acid (PLA) composites at two fiber loading contents (30 and 50 wt.%) are investigated in this work. Moisture adsorption was evaluated at 30, 50, 75 and 95% relative humidity, and water resistance was determined after a 28-day immersion period. The cone calorimetry technique was used to investigate response to fire. The fiber surface treatment resulted in the removal of cell wall components, which increased fiber individualization and homogeneity as shown in scanning microscopic pictures of the composite cross-section. Although the improved fiber/matrix bonding increased the composite’s water resistance, the different fiber treatments generated equal moisture adsorption results for the 30 wt.% reinforced composites. Overall, increasing the fiber amount from 30 to 50 wt.% increased the composite sensitivity to moisture/water, mainly due to the availability of more hydroxyl groups and to the development of a higher pore volume, but fire protection improved due to a reduction in the rate of thermal degradation induced by the reduced PLA content. The new Oswin’s model predicted the composite adsorption isotherm well. The 30 wt.% alkali and silane treated hemp fiber composite had the lowest overall adsorption (9%) while the 50 wt.% variant produced the highest ignition temperature (181 ± 18 °C).

In recent times, demand for light weight and high strength materials fabricated from natural fibres has increased tremendously. The use of natural fibres has rapidly increased due to their high availability, low density, and renewable capability over synthetic fibre. Natural leaf fibres are easy to extract from the plant (retting process is easy), which offers high stiffness, less energy consumption, less health risk, environment friendly, and better insulation property than the synthetic fibre-based composite. Natural leaf fibre composites have low machining wear with low cost and excellent performance in engineering applications, and hence established as superior reinforcing materials compared to other plant fibres. In this review, the physical and mechanical properties of different natural leaf fibre-based composites are addressed. The influences of fibre loading and fibre length on mechanical properties are discussed for different matrices-based composite materials. The surface modifications of natural fibre also play a crucial role in improving physical and mechanical properties regarding composite materials due to improved fibre/matrix adhesion. Additionally, the present review also deals with the effect of silane-treated leaf fibre-reinforced thermoset composite, which play an important role in enhancing the mechanical and physical properties of the composites.

“…One of the strongest natural fibers available today is abaca fibers (AF), includes a low‐cost agro‐based renewable material, and does not leave any residues or byproducts during processes that are toxic. [ 22 ] Although the current market utilizing the AF strands for twines and ropes; however, it gradually picking up significance as reinforcement for polymer composite materials. Even, the abaca is being used for “soft” applications in the automotive industry as a filling material for bolster and interior trim parts.…”

This research focused on the fabrication of flame-retardant green composites by utilizing inexpensive bio-waste eggshell powder (ESP) as a flame-retardant additive to polypropylene (PP)/abaca fibers (AF) composites (AF/ESP-PP). The optimization of AF reinforcement in composites examines various wt% (5-20) of fibers in the light of mechanical properties. Fifteen weight percentage of AF reinforcement showing the highest tensile (26 MPa) and flexural (46 MPa) strength compared to the remaining composites. Spectral (Fourier-transform infrared spectroscopy) and micro (scanning electron microscope) analysis support the improvement of mechanical strength of the composites in connection with the interaction between AF with PP. Besides, different wt% (2, 4, 6, and 8) of ESP were incorporated into the AF/PP composites and examine the thermal and flame-retardant properties by thermogravimetric analysis, horizontal burn test, and microcalorimetry, respectively. An improvement in thermal stability 9.82 wt% at 700 C, horizontal burn test results and decrement in peak heat release rate to 947 W/g.
