Abstract

The invention discloses a test device and a test method for testing performance of a fiber composite grid material. The test device comprises composite grid fixtures and a clamping device, wherein theclamping device comprises an upper oppositely pulling clamping device and a lower oppositely pulling clamping device; sliding slots 1 are formed in the upper oppositely pulling clamping device and the lower oppositely pulling clamping device; the composite grid fixtures are connected to the upper oppositely pulling clamping device and the lower oppositely pulling clamping device in a sliding manner through the sliding slots 1 respectively; the top end of the upper oppositely pulling clamping device and the bottom end of the lower oppositely pulling clamping device are connected to an upper cross beam and a lower cross beam of a universal testing machine in a clamping manner respectively; a standard component is arranged between the composite grid fixtures; the test device further comprises slidable steel plates and transverse rib fixing devices. Through the test device and the test method for testing the performance of the fiber composite grid material, provided by the invention, an overall oppositely pulling test of multiple ribs of a fiber composite grid can be completed, the strength of joints can be tested and influence of the joints on the strength of the composite grid material can be tested; not only the working efficiency is improved, but also the test device can be reused, and thus the cost is saved.

Description

technical field [0001] The invention relates to the technical field of civil engineering material performance testing equipment, and more specifically relates to a testing device and a testing method for the performance of a fiber composite grid material. Background technique [0002] Fiber Reinforced Plastic (FRP) refers to a composite material formed by impregnating one or more high-performance continuous fibers such as carbon fiber, aramid fiber, high glass fiber, and basalt fiber in a resin with good corrosion resistance. , has the advantages of light weight, high strength, good durability, strong corrosion resistance, and strong designability. Fiber composite mesh is a new product form in fiber reinforced composite materials. In addition to the above advantages, its transverse and longitudinal ribs and nodes have high strength and stiffness. When the fiber composite grid is actually applied to the structure (reinforcement or new building), it is necessary to test the m...
