This paper numerically investigates the flexural response of concrete beams reinforced with steel and four types Fiber-Reinforced Polymers (FRP), i.e., Carbon FRP (CFRP), Glass (GFRP), Aramid (AFRP), Basalt (BFRP). The responses forty two boundary conditions (simply supported over-hanging beams) were determined using ABAQUS. Subsequently, finite element models validated experimental results. Ev...

Due to the high cost of laboratory testing, many researchers are considering developing methods predict behavior unreinforced and reinforced wood beams. This work aims create either numerical or analytical models useful for extrapolating already conducted tests other schemes/materials used as reinforcement. In case timber structures, due complexity timber, this task is difficult. The first part...

Fibre-reinforced polymer(FRP), also Fibre-reinforced plastic, is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, or aramid, al‐ though other fibres such as paper or wood or asbestos have been sometimes used. The poly‐ mer is usually an epoxy, vinylester or polyester thermosetting plastic, and phenol formaldehyde resins are still in use...

Columns at the ground floor and parking garages that could be hit by a car pose significant risk to structural stability of building superstructures. Generally, these columns are not built sustain lateral impact force generated car–column collision. In this study, performance axially loaded retrofitted reinforced concrete (RC) against is evaluated using finite element (FE) simulation. The FE mo...

Aramid fiber-reinforced plastic (AFRP) composites are widely used in aerospace, rail transit, marine and military industries, due to their high specific strength, impact resistance, fatigue resistance excellent designable properties. In order meet different application requirements, cutting processes need be carried out, such as window opening, edge slit cutting. However, the characteristics of...

Because of their high strength and energy dissipation capacity, aramid fibers are used widely as the material of choice for body armor and similar applications. Their use as reinforcement of concrete panels, whether prestressed or not, poses significant challenges because of their relatively low fiber-to-fiber friction coefficient and limited bond strength between fibers and cementitious matrix...

Nanoscale polymeric fibers are expected to bring about exceptional mechanical and optical properties in composite materials related to the better integration of different properties between fibers and polymers. The discovery of the first aramid nanofiber dispersion from commercial para-aramid macrofibers similar to Kevlar developed by DuPont allowed the emergence of an innovative nanoscale buil...

In this study, a total of 6 different composites were obtained by adding 5%, 10% and 15% chopped aramid fiber reinforcement in mm dimensions to each the polypropylene polyethylene matrix elements under same production method conditions. The materials mixed using extrusion then formed into plates press molding technique. Tensile charpy tests these performed their mechanical properties examined. ...
