“…Meanwhile, this reinforcing element only can provide required strength and stiffness to the material. There are several synthetic fibres glass [65], carbon [66], kevlar [67], basalt [68] and various natural fibres such as sisal [69], banana [70], hemp [71], flax [72], kenaf [73] and coir [74], among others, have been used as successful reinforcement elements in various polymer systems. However, the effective suitability of the polymer matrix and reinforcement used in composite pipe fabrication depends upon many factors.…”

Polymer nanocomposites have been gaining attention in recent years. The addition of a low content of nanomaterials into the matrix improves mechanical, wear, thermal, electrical, and flame-retardant properties. The present work aimed to investigate the effect of graphene and hexagonal boron nitride nanoparticles on Kevlar and hybrid fiber-reinforced composites (FRP). Composites are fabricated with different filler concentrations of 0, 0.1, 0.3, and 0.5 wt.% by using a hand layup process. Characterizations like tensile, flexural, hardness, and impact strength were evaluated separately, heat deflection and viscosity properties of the epoxy composites. The dynamic viscosity findings indicated that a higher concentration of filler material resulted in nano-particle agglomeration. Graphene filler showed superior properties when compared to hexagonal boron nitride filler. Graphene showed optimum mechanical properties at 0.3 wt.%, whereas the hBN filler showed optimum properties at 0.5 wt.%. As compared to Kevlar composites, hybrid (carbon–Kevlar) composites significantly improved properties. As compared to graphene-filled composites, hexagonal boron nitride-filled composites increased scratch resistance. Digimat simulations were performed to validate experimental results, and it was observed that hybrid fabric composites exhibited better results when compared to Kevlar composites. The error percentage of all composites are within 10%, and it was concluded that hybrid–graphene fiber composites exhibited superior properties compared to Kevlar composites.

“…Babazadeh et al [ 6 ] observed that the flexural properties of composite tubes made of Kevlar, glass, and carbon fibers had highest flexural strength of 91.08 MPa, which were 13% and 132% higher than the individual Kevlar and carbon fiber composites. Hallad et al [ 7 ] observed the flexural behavior of 0.1 to 0.4 wt.% of Kevlar fiber pulp reinforced polymer composites. Maximum flexural property was obtained for 30 wt.% of kevlar pulp composite, and it higher by 48% when compared to dry pulp composite.…”

Service life prediction of lightweight fiber reinforced polymer composites is essential for activating the recycling process in the future. The present work investigates the amount of material diffusion, long‐term flexural performance, and prediction of service life for Kevlar fiber mat reinforced Epoxy Composites (KEC). Hand layup technique and compression molding were used for manufacturing the composites and they were submerged in water at 20, 40, and 60 °C temperatures for different time durations like 50, 150, and 300 days. As per the ASTM D 790 standard, the three‐point flexural test was conducted on unaged and aged composites. Fick's law was used to calculate the diffusivity, and the Arrhenius principle was used to calculate the service life and activation energy. Experimental outcomes portrayed that the maximum water absorption for KEC occurred at 60 °C for all immersion periods. Moisture absorption was purely depending on the temperature and duration of the aged composite. Dry KEC showed higher flexural strength than aged composite. The higher flexural strength retention of 58.56% with the maximum service life of 100 years was found for KEC at 40°C. It shows the service life of the kevlar fiber reinforced epoxy composites.
