Mechanical properties of the fibers extracted from the areca are determined and compared with the other known natural fiber coir. Further these Areca fibers were chemically treated and the effect of this treatment on fiber strength is studied. Areca fiber composite laminates were prepared with randomly distributed fibers in Maize stalk fine fiber and Phenol Formaldehyde. Composite laminates wer...

Three different laminated composites are used in this study: carbon fiber, woven glass and glass-fiber-reinforced epoxy. The composite laminate structures were fabricated using the hand lay-up technique at room temperature. laminates reinforced with epoxy resin, fibers (CFRP), (GFRP-W), random-orientation (GFRP-R) to obtain eight layers. wear test was performed a pin-on-disc tribometer five loa...

design of bridge deck with long-term strength, durability and permanence is a significant interest for engineers. one applicable solution to this challenge could be via using hybrid system consisting of conventional materials such as concrete and steel with frp plates which is also known as composite deck. since these deck are relatively new so their performance is not completely known. the pre...

Glass fiber reinforced polymer (GFRP) composites are widely used in infrastructure applications including water structures due to their relatively high durability, high strength to weight ratio, and non-corrosiveness. Here we demonstrate the potential use of carbon nanoparticles dispersed during GFRP composite fabrication to reduce water absorption of GFRP and to enable monitoring of moisture d...

The effect of adding different percentages nano-graphene oxide (NGO) into the epoxy resin on mechanical properties NGO/epoxy and maximum peeling force fiber-metal laminates (FMLs) with composite cores are investigated in this paper. Three NGO including 0.1, 0.35 0.50 weight (wt. %) used to fabricate tensile test samples NGO/epoxy. Hand lay-up method is FML specimens glass fiber reinforced plast...

Glass fibre reinforced plastic (GFRP) is considered as structure support and insulating material for the new superconducting FAIR magnets. GFRP (G11) is a composite material consisting of woven glass fibres (volume fraction ~50 %) and cured polymer resin (e.g. amine-cured epoxy). The material will be exposed to cryogenic temperatures, high radiation levels and dynamic mechanical loads (Lorentzi...

Embedding FBG strain sensors within a GFRP sandwich composite material allows early detection of internal defects. However, the sensors need to survive the manufacturing process to provide this capability. Vacuum infusion is commonly used to manufacture GFRP sandwich composite materials but, it needs to be modified to accommodate the embedding process. A stage by stage procedure is demonstrated...
