Manufacturing device and manufacturing method of CFRP/steel plate combined test piece

Abstract

The invention discloses a manufacturing device and a manufacturing method of a CFRP / steel plate combined test piece. The manufacturing device comprises a bottom plate, a control plate, a cover plate and a pressing device, a vernier caliper is fixedly mounted on the bottom plate, and a measuring plate is arranged on the vernier caliper; a groove is formed in the bottom plate; a first horizontal bubble is arranged on the bottom plate; a plurality of first positioning holes are formed in the bottom plate; the control panel is provided with an adhesive layer groove which penetrates through the control panel; a neck is formed in one side of the control panel; a second horizontal bubble is arranged on the control panel; a plurality of second positioning holes are formed in the control panel; a plurality of third positioning holes are formed in the cover plate; the bottom plate, the control plate and the cover plate can be positioned through the first positioning holes, the second positioningholes and the third positioning holes; and the bottom plate, the control plate and the cover plate can be pressed through the pressing device. According to the invention, the glue layer thickness ofthe CFRP / steel combined test piece and the relative position of the CFRP steel can be accurately controlled, and the test accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of steel structure reinforced by carbon fiber composite materials, and in particular relates to a manufacturing device and a manufacturing method of a CFRP / steel plate composite test piece. Background technique [0002] As a new type of material, carbon fiber reinforced composite (CFRP) has the properties of high strength, light weight, fatigue resistance and corrosion resistance, and has been widely used to strengthen steel structures. [0003] In order to evaluate the effect of using CFRP to strengthen steel structures, it is necessary to make CFRP / steel composite specimens for loading tests. At present, there are problems such as difficulty in controlling the thickness of the adhesive layer in the production process of the test piece, and difficulty in aligning the position of the steel plate and the CFRP material during the pasting process, which seriously affects the quality of the test piece and the ef...

AI Technical Summary

Problems solved by technology

The invention provides a manufacturing device and method for a CFRP / steel composite test piece capable of accurately controlling the thickness of the glue layer and the position of the components, which can solve the difficulty in the thickness of the glue layer of the CFRP / steel composite specimen and the relative position of the CFRP steel during the pasting and reinforcement process. The problem of control can make the thickness of the glue layer of the CFRP / steel composite specimen and the relative position of the CFRP steel be accurately controlled, and the accuracy of the test can be improved.
