Description

TECHNICAL FIELD

[0002] Impregnated fabric is a kind of composite material semi-finished product made by impregnating fabric with resin solution and drying, curing and other processes, which belongs to new materials. Its core feature is the close combination of resin and fiber, which gives the material high strength, wear resistance, corrosion resistance and other properties. It is widely used in laminating, rolling, tape winding and pasting forming industries. However, such impregnated fabric needs professional tensile property detection during production to determine key indicators such as tensile strength and elongation at break.

[0003] Therefore, the patent with publication number CN115753394A discloses an impregnated fabric elastic tensile detection mechanism, which includes a base plate, a support rod and a connecting frame. The support rods are installed on both sides of the top of the base plate. The connecting frame is installed inside the support rod. The fixed plate is installed inside the connecting frame. The fixed device is installed on both sides of the top of the fixed plate. The sliding device is installed on both sides of the inside of the fixed plate. The fixed plate and the fixed device are provided with an impregnated fabric body. The fixed device includes a first fixed column, a first clamping plate and a first sliding block. The first fixed column is installed on both sides of the top of the fixed plate. The first clamping plate is provided above the first fixed column. The first sliding block is installed below the first clamping plate. The first sliding block is installed inside the connecting frame. The fixed groove is provided on the outer wall of the fixed plate. The present application uniformly stresses the fixed position of the four edges of the impregnated fabric, prevents uneven stress from causing impregnated fabric rupture, and improves the protection effect of the device on the impregnated fabric.
