A concise state-of-the-art survey of fiber-reinforced polymer ~also known as fiber-reinforced plastic! composites for construction applications in civil engineering is presented. The paper is organized into separate sections on structural shapes, bridge decks, internal reinforcements, externally bonded reinforcements, and standards and codes. Each section includes a historical review, the curre...
The purpose of this article is to investigate the influences of carbon fibers on the fracture mechanism of carbon fibers both in macroscopic view and microscopic view by using single-point flying cutting method. Cutting tools with three different materials were used in this research, namely, PCD (polycrystalline diamond) tool, CVD (chemical vapor deposition) diamond thin film coated carbide too...
Carbon-fiber reinforced composites are widely used in the industry. One of the key features regarding their quality and usefulness is related to the fiber orientation and contend. One technique that is used to test this kind of material is Infrared Thermography (IT). In this paper it is presented a technique based on diode-laser spot heating to measure fiber orientation on the surface of a carb...
Ozone treatment of isotropic-pitch-based carbon fiber was found to increase the surface oxygen concentration and change surface oxygen from C–O to CNO, thereby causing the contact angle between fiber and water to be decreased to zero. Thus, the bond strength between fiber and cement paste was increased and the tensile strength, modulus and ductility of carbon fiber reinforced cement paste were ...
This paper presents results of testing eccentrically loaded columns externally wrapped with two types of materials. Six cylindrical (205 mm diameter and 925 mm height) plain columns were cast and tested. Half of the columns were wrapped with GFRP and the other half with CFRP. All columns were tested by applying an axial load at 50 mm eccentricity. In each group (GFRP or CFRP wrapped) of columns...
The use of carbon fiber reinforced plastic (CFRP) is increasing in engineering applications such as aerospace, automobiles, defense, and construction. Excellent strength-to-weight ratio, high impact toughness, corrosion resistance make CFRP highly suitable for aerospace applications. Curing temperature, curing time, autoclave pressure are among the most important parameters affecting properties...
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...
