Problems solved by technology

When testing the mechanical properties of materials, it is usually carried out in the laboratory. In the laboratory, the tensile and compressive properties of the material are usually tested with a separate testing machine, which brings great challenges to the test. Inconvenient, and the existing mechanical performance testing machine is large in size and inconvenient to move, which brings inconvenience to on-site testing in other occasions

Abstract

The invention discloses a mechanical property testing system for composite materials. The mechanical property testing system comprises a stretching device, a compression device and a detecting device;the stretching device and the compression device are arranged integrally, the stretching device is used for stretching the composite materials, the compression device is used for compressing the composite materials, and the detecting device is used for testing the mechanical properties of the stretched composite materials or the compressed composite materials and obtaining mechanical property parameters. According to the mechanical property testing system for the composite materials, the stretching device and the compression device are arranged integrally, the volume is decreased, and the mechanical property testing system is suitable for field test in various occasions.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a testing system for mechanical properties of composite materials. Background technique [0002] Composite materials are composed of two or more materials with different properties, which are composed of materials with new properties on a macro or micro level through physical or chemical methods. Various materials learn from each other in terms of performance and produce synergistic effects, so that the comprehensive performance of composite materials is better than that of raw materials to meet various requirements. The matrix materials of composite materials are divided into two categories: metal and non-metal. The basic metals are aluminum, magnesium, copper, titanium and their alloys. Non-metal bases mainly include synthetic resin, rubber, ceramics, graphite, and carbon. When testing the mechanical properties of materials, it is usually carried out in the labora...
