Subsequently, detailed information is provided about the following three main types of FRP shapes used in structural applications: (1) glass fibre-reinforced polymer (GFRP) pultruded profiles; (2) FRP rebars and (3) FRP strengthening systems. For each of these three main FRP typologies, the following aspects are discussed: geometries, …

Pultrusion is a continuous process used to manufacture fiber-reinforced polymer (FRP) composite profiles with a constant cross section. A composite is a composition material, typically consisting of a thermoset or thermoplastic polymer, reinforced with glass, carbon, aramid fibers, or combinations thereof. The pultrusion process originated in ...

The FRP plates investigated where produced by pultrusion process, as already mentioned, with the external load orthogonal respect the fiber's orientation; each final FRP plate, because of its high thickness, was then made as a sum of two glued thinner FRP pultruded plates. The FRP connections analyzed are of two types, with different ...

Offered in a variety of colors and a wide range of sizes, Fastec International's pultruded fiberglass-reinforced polymer (FRP) shapes are also durable, lightweight, longer-lasting than traditional building materials, and won't swell, warp, or shrink with exposure to the elements. This means you get a better product and spend less time and ...

specifically, pultruded FRP beams. Pultruded FRP structural beams are produced in standardized profile shapes such as, I-beams, wide-flange (WF) beams, channels, and angles. The work described in this paper concentrates on commercially produced standard shapes because it is felt that the widespread use of FRP structural members will depend, …

The insufficient resistance of the supports in fixing the GFRP profile motivated the development of the second beam series. Two rectangular 550 × 550 × 40 mm slabs and eight 100 mm cubes were ...

The experimental results showed that the space structure with pultruded FRP profiles connected by aluminum bolt-ball connecting system had excellent structural stiffness. The metal connections in hybrid FRP-aluminum structures prevented premature shear failure. Bai et al. [23] proposed a space truss composed of all composite materials. …
