Product Description
Glass fiber reinforced barGlass fiber reinforced composites (GFRP) is a reinforcement material composed of high-performance glass fiber, epoxy resin, curing agent and other materials by appropriate molding and curing process; the fiber has high tensile strength and is the main provider of the strength of glass fiber reinforcement. It mainly plays the role of bearing load. The matrix material has the role of bonding and transmitting shear, and its physical properties can affect the physical properties of fiber reinforced materials Glass fiber reinforcement is a kind of fiber-reinforced composite material, which has the characteristics of light weight, high strength, corrosion resistance, easy cutting and non-magnetic. It is widely used in pavement and bridge deck pavement, foundation pit construction, coastal engineering, tunnel new method construction, subway continuous wall, retaining pile, etc.Appearance The shape of GFRP reinforcement should be in the form of thread. The surface texture of the threaded rod body should be uniform without bubbles and cracks. The thread tooth shape and pitch should be neat without damage. Resin matrix For resin matrix, it is recommended to use vinyl resin and epoxy resin ormixed resin of vinyl resin and epoxy resin.When unsaturated resin (o-benzene resin and m-benzene resin) is usedDuring the production of glass fiber reinforced bar, due to the erosion of alkaline environment, the research shows that the mechanical properties of glass fiber reinforced bar will deteriorate obviously. For example, if it is placed in alkaline liquid for about one month, the tensile strength may decrease by more than 30%. Attention should be paid to this problem in construction and use. Density The density of GFRP reinforcement material shall be between 1.9 g / cm3 and 2.2g/cm3. Specifications The nominal diameter range should be 8 mm ~ 36 mm. It is recommended that the nominal diameter specifications of common GFRP Bars are 20 mm, 22 mm, 25 mm, 28 mm and 32 mm. Excellent mechanical properties: 1. High bearing capacity, strong tensile capacity, the strength of the rod body is twice that of the threaded reinforcement with the same diameter, but the quality is only 1 / 4 of that of the reinforcement; 2.The elastic modulus is stable, about 1 / 3 ~ 2 / 5 of the reinforcement; 3. Electrothermal insulation, thermal expansion coefficient closer to cement than reinforcement; 4. Good corrosion resistance, suitable for use in wet or other corrosive environments such as water conservancy, bridges, wharfs and tunnels; 5. The shear strength is low, and the ordinary shear strength is only 50 ~ 60MPa, which has excellent cutting performance.Performance index of glass fiber composite reinforcementSerial
