“…Graphene nano platelets (GnPs) which has been recently developed single layered carbon nano material is a useful polymer reinforcement material which has a large surface area led to increase the stress transfer between polymer and nano material [4,5,6,7]. Graphene has a 2-D nanostructure and leads an enhancement in toughness of fibers [8,9].…”

Fiber reinforced polymer composite materials show several superior properties over conventional engineering materials; on the other hand, most of composite materials also have some drawbacks such as brittle behavior of matrix. This study is aimed to improve the impact response of composite material by adding nano particle into epoxy matrix. For this purpose; an experimental study was conducted to investigate the effect of graphene nano particles inclusion in epoxy resin with glass fiber reinforced composite plate on the Charpy impact response. Glass fiber reinforced (GFR) epoxy composite plates were produced with various graphene nano platelets content such 0, 0.1, 0.25 and 0.5 wt%. Low velocity impact response was investigated by using Charpy impact test method. Impact energy and impact damage results presented in detail.

The development of personal protection systems with improved ballistic performance and reduced weight has received a great interest in the last decade with the unfortunate ever-increasing threats and conflicts. In this review, the ordinarily polymeric fibers used in body armors manufacturing were first reported, then some nanomaterials, such as carbon nanotubes and graphene with advanced structural and mechanical properties, as well as their potential reinforcement of armor composites were investigated through some recent studies available in the literature. Additionally, natural fibers integrated into multilayered armor systems, and ballistic tests which endorse their future importance were also cited. This short review which sheds light on novel materials used in personal armor systems, a specific and an important topic that was not previously reviewed, aims to provide to the new researchers, engineers and manufactures in this field some guidelines about what are the promising materials that can be used in order to construct the ultimate body armors of the future.

“…Materials and structural design such as geometric dimension and fiber orientation are essential for multiscale models to generate local material constitutive relationships used in addressing crashworthiness and safety and durability challenges. [ 14 ],[ 15 ] While the structural design of the LGFR‐PP material bumper beam under low‐velocity impact conditions has not been comprehensively studied. The crashworthiness and lightweight of automobile are complex system engineering.…”

There is an increasing demand for lightweight materials in the automobile industry. In this study, the crashworthiness and crash safety performance of automobile bumper beams made of long glass fiber‐reinforced polypropylene (LGFR‐PP) composites were evaluated. First, LGFR‐PP with the 40% glass fiber was prepared by the hot‐melt impregnation method, the mechanical properties and Poisson's ratio of the LGFR‐PP specimens were tested, which are essential for the finite element analysis. Then a finite element model of aluminum alloy and LGFR‐PP bumpers was established to obtain their peak collision force, maximum intrusion, and energy absorption values under longitudinal and angular low‐speed collision conditions. Subsequently, the multi‐objective optimization was generated using optimized Latin square sampling and response surface test design, and the section thickness of the bumper beams was optimized. The results showed that Swift and Hockett's hardening model is suitable for the LGFR‐PP material. Based on the principle of equal stiffness, the mass of the anti‐collision beams made of LGFR‐PP is reduced by 17.4%, the specific energy absorption (SEA) is increased by 6%, and the cost is reduced by 69%, and both the peak impact force and the amount of collision intrusion are reduced. The multi‐objective optimized Latin hypercube experimental showed that the continuously variable cross‐section beam based on the thickness optimization balanced the impact resistance especially SEA and lightweight performance very well.
