Abstract

The present invention is an encapsulation method of composite reinforced wall plate axial compression test piece. The method comprises following steps: mixing a main agent and a curing agent, pouringthe mixture into a glue filling box 1, inserting one end of a composite reinforced wall plate axial compression test piece 2 into the glue filling box, and completing fixed connection after curing. The method is characterized in that: adding quartz sand to a main agent, mixing uniformly, mixing with a curing agent, and finally pouring into the glue filling box; wherein ratio of an added mass of the quartz sand to a total mass of the main agent and the curing agent is: 0.5 ~1.2. The method can effectively avoid the problem of excessive temperature of glue liquid in the encapsulation process, improves quality of encapsulation colloid, and thereby reduces deviation of compression test data.

Description

technical field [0001] The invention relates to a filling and sealing method for a composite material reinforced wall plate axial pressure test piece, which relates to the field of composite material manufacturing. Background technique [0002] With the continuous improvement of the performance and manufacturing technology of composite materials, composite materials have become the main structural materials of aerospace vehicles. Compressive strength is one of the parameters commonly used to characterize the mechanical properties of composite materials, and the compressive strength of materials can be determined by performing compression tests. In the prior art, the compressive strength is usually measured by an axial compression testing machine after preparing an axial compression test piece. This method requires extremely high processing accuracy and surface quality of the test piece. In recent years, engineers at home and abroad generally use the method of potting compos...
