The failure of an AL6061-T6 and Kevlar-29 composite plate under high-velocity impact from an S-S (structural Steel) projectile tool was investigated using the nonlinear explicit finite element software, ANSYS AUTODYAN. Two velocity ranges 350 m/s and 700 m/s were used for FEM simulation. It was analyzed that AL6061-T6 is more resistant than KELVAR 29 at both ranges but Kevlar 29 is light in wei...

Additive manufacturing (AM) has been used widely to produce three-dimensional (3D) parts from computer-aided design (CAD) software. Traditional Fused Deposition Modeling (FDM) 3D printed polymer lack the necessary strength be for functional in service. The potential of printing continuous fiber reinforced composites resulted with better mechanical properties and enhanced performance. Very few s...

To advance ecological civilization, developing sustainable, eco-friendly high-strength and ultra-tough alternatives to non-sustainable synthetic fibers, such as nylon, is crucial. This necessitates a deeply scientific understanding of the fundamental determinants fiber strength toughness, well overcoming engineering challenges for cost-effective, large-scale production high-performance silk fib...

Abstract In this study, a methodology combining finite element analysis (FEA) and artificial neural network (ANN) through multilayer perceptron architecture was utilized to predict the impact resistance behavior of hybrid non-hybrid fabric reinforced polymer (FRP) composites. A projectile at 250 m s −1 velocity considered for high simulations. The Kevlar, carbon glass fabric-based epoxy composi...

Claisen rearrangement reaction was employed for the first time to obtain a novel PPTA bearing reactive allyl and hydroxyl groups which may act as a sizing agent of Kevlar fibers to improve the interface structure and interfacial adhesion of rubber or epoxy based composites.
