Thermo-set based composites using epoxy resin systems currently dominate the composite industry. Glass-reinforced epoxy composites are extensively used in the structural composites of aircraft industry due to low shrinkage, ease of fabrication, chemical resistance, and higher mechanical and electrical properties. The above characteristics coupled with techno-economic considerations are mainly r...

Environmental awareness and the need for sustainable construction inspired researchers practitioners to explore innovative alternatives that might reduce greenhouse gas emissions energy use related excessive structural work. One such alternative is utilization of Fiber-Reinforced Polymer (FRP) bars as a reinforcement in reinforced concrete members. FRP possess favorable characteristics like hig...

Mechanical properties of products produced with the Fused Deposition Modeling (FDM) process are known to be dependent on bead direction, especially when short fiber reinforcement is added to the polymer filament feedstock. As a result, the structural performance of fiber-filled FDM parts is expected to be improved by simultaneously computing preferred deposition directions while optimizing the ...

page 62 Abstract: A fiber pullout test for examining controlled interfaces in fiber reinforced polymers has been designed and demonstrated. This test has been utilized in determining interfacial fracture toughness for sapphire/epoxy single fiber composite specimens. Some of these specimens incorporated a self-assembled monolayer at the sapphire/ epoxy interface as a means of adhesion control—th...

A single-fiber pull-out model composite for an aramid/epoxy system was specially designed to measure the stress distribution of the aramid fiber embedded in the matrix using micro-Raman spectroscopy. The stress transfer length of the fiber obtained was about 400-500 μm, which was equal to the result of FEM analysis. Just after the initiation and propagation of the fiber/matrix interfacial debon...

This paper presents a concise state-of-the-art review on the use of Fiber Reinforced Polymers (FRPs) in bridge engineering. The is organized into commonly used FRP components, and different materials/manufacturing techniques for repairing construction bridges. Efforts have been made to give clear view bridges using most relevant literature. FRPs certain desired properties like high strength wei...
