This work aims to investigate the effect of SiO 2 nanoparticles on the mechanical properties of pineapple leaf ber (PALF) epoxy hybrid composites. The compression molding process was used to create the composite. To achieve the aforementioned goals, the blends were made using 25% PALF and varied weight proportions (3wt%, 6wt%, and 9wt%) of SiO 2 nanoparticles. Tensile, bending, impact, interlaminar shear, shoreline D hardness, and dynamic mechanical analysis were all evaluated. SEM was used to examine the morphology of the materials, and an FTIR spectrometer was used to look for the presence of organic chemicals in ber-reinforced composite materials. The ndings show that adding 25% PALF ber and 6% SiO 2 nanoparticles (D-type) to the epoxy polymer improved the thermal and mechanical properties of the composites. It can be attributed to the improved interaction and homogeneous dispersion of the llers and epoxy polymers. Moreover, the water uptake parameters of all samples were studied. The ndings showed that the inclusion of reinforcements boosts the water uptake of the composite signi cantly. The initial deterioration rate of the SiO 2 -incorporated hybrids is almost the same, at about 400°C, which is considerably greater than that of the beginning breakdown temperatures of PALF (300°C), according to the thermography study. This might imply that the ber and polymers form a stronger bond, reducing polymer movement and increasing the thermostability of the combination.

“…Fillers or additives are also incorporated into polymer composites to modify the process ability, reduce the costs and improve the mechanical/physical properties. 7,26 FRPCs are of the types of organic composites that have been manufactured with a wide range of polymers, reinforcements and fillers. 6 The most popular polymers, reinforcements and fillers are presented in Figure 2.Figure 2.General classification of the main components of FRPCs and the mostly used material types.…”
Fiber reinforced polymer composites (FRPCs) have gained great progress in a wide range of applications from construction and building structures to automobile and vehicle systems. During the operational lifetime, some FRPCs are exposed to various environmental conditions such as thermal cycles and thermal shocks. Fluctuation of the ambient temperature in the forms of thermal shocks or thermal cycles is one of the most important factors that deteriorate the durability and performance of the FRPCs. Compared to ceramic composites, less attention has been paid to the effects of thermal shocks and thermal cycles on the physical/mechanical properties of FRPCs. A comprehensive insight for the future advancements in this field is essential to possibly reduce the failure risks of FRPCs under thermal shocks and thermal cycles. The present work provides a comprehensive review on the physical/mechanical behavior of FRPCs under thermal cycles and thermal shocks. This work also provides a broad review on several factors that determines mechanical behavior of FRPCs, such as polymeric matrix, fiber type, incorporated nanofillers and fiber/polymer interface. Recent studies denoting important aspects and possible problems in mechanical performance of FRPCs under thermal shocks are also summarized.

Natural fiber composites are not suitable for use in industries due to their flammability and low thermal resistance. Inorganic metal‐based fillers are known to enhance the flammability and thermal resistance of composites, while the thermal and fire‐retardant properties of organic fillers are not commonly known. This study evaluated the mechanical, thermal, and flammability properties of Ceiba petandra fiber (CPF)‐reinforced composites, which were added with snail powder (SP). To study the thermal resistance of the composite, a dynamic mechanical analyzer (DMA) and thermogravimetric analysis (TGA) were applied. SP Filler concentration increased the composite's tensile strength and thermal resistance. DMA test results showed the same trend as the composite's density value. The flame rate parameters of the composite, including the percentage of char yield and the limitation index oxygen (LOI), rose as the SP filler increased. However, the flame rate of the composite dropped because SP filler inhibited the movement of oxygen, combustible gas, and polyester degradation products. The addition of organic fillers in natural fiber composites promises better flammability and thermal resistance.
