This paper explores the use of Carbon fiber reinforced polymer (CFRP) material for strengthening of steel bridges. The research work includes an experimental program to study the effectiveness of using very small diameter CFRP strands, configured in a sheet format, for strengthening of steel structures. The experimental program includes scaled steel-concrete composite beams strengthened with th...

Abstract The mechanical properties of carbon fiber-reinforced epoxy composites were identified by adding carbon-based nano-reinforcements, such as multi-wall nanotubes (CNTs) and graphene platelets (GP), into the matrix conducting suitable experiments. main focus this study is to compare tensile modulus, strength, flexural thermal conductivity with nanoparticle reinforcement. results revealed t...

Although laser drilling of carbon fibre-reinforced polymer (CFRP) composites offers the advantages zero tool-wear and avoidance fibre delamination compared with mechanical drilling, it consumes considerably more energy during process. This research shows that by using a new, stepped parameter parallel ring hole method, an saving 78.10% 18.37 gCO2 reduction for each hole, while improving product...

The present paper investigates the response a sandwich composite laminate that involves intraply hybrid carbon fiber reinforced polymer (CFRP)/Dyneema core under impact and post-impact tests. This was designed to gain high elasticity stiffness/weight ratio of Dyneema fibers while maintaining structural integrity CFRP at core. Low-velocity compression after tests were employed evaluate damage re...
