Composite material tensile fixture with load and environment coupling effect and using method thereof

Abstract

The invention discloses a composite material tensile fixture with a load and environment coupling effect and a using method thereof, and relates to the technical field of composite material tensile testing devices. The composite material tensile fixture comprises a fixed clamping end, a movable clamping part, a tail supporting piece, a long screw rod and a spring, wherein the fixed clamping end isarranged at one end of the long screw rod, the tail supporting piece is arranged at the other end of the long screw rod, the movable clamping part is movably arranged on the long screw rod, the longscrew rod is sleeved with the spring, the spring is located between the fixed clamping end and the movable clamping part, and a first nut is arranged at the position, close to the fixed clamping end,of the spring on the long screw rod. Under the condition that electronic equipment is not needed, accurate and quantitative tensile loads are provided for a composite material test in an extreme environment, a service simulation test that the composite material bears long-time stable accurate tensile loads in various extreme environments is completed, and the tensile fixture is simple in structure, stable in working condition and not prone to damage; the test method is simple, convenient and high in flexibility, and test conditions and steps can be automatically adjusted according to differentenvironmental simulation requirements and different types of samples.

Description

technical field [0001] The invention relates to the technical field of composite material tensile testing devices, in particular to a composite material tensile fixture and a method for using the coupling effect of load and environment. Background technique [0002] At present, composite materials are gradually attracting everyone's attention. With the gradual expansion of the application field of composite materials, they are faced with a variety of service environments. However, in different environments, there are few studies on the service performance of composite materials under long-term tensile loads. The main difficulty is that the electronic instruments and digital displays that apply loads cannot work normally in some extreme environments, making the composite The continuous tensile load of the material sample and the service performance test under the coupling effect of multiple environments cannot be effectively carried out. The tensile test device can apply acc...
