Embodiment Construction

[0035] Below in conjunction with example the present invention is described in detail.

[0036] Aiming at the technical defect of the existing single thermal factor aging equipment, the present invention processes and manufactures a set of accelerated thermal aging test equipment capable of realizing multi-station, mechanical type and loadable stress. The equipment mainly consists of steel frame 5, balance beam 4, counterweight 6, temperature and humidity control system, humidity control system, stress and strain measurement structure, and balance adjustment system.

[0037] The temperature and humidity control system mainly includes an aging box 11. The aging box 11 is divided into a temperature and humidity control area and a heating and humidifying area. The upper and lower ends of the aging box 11 are provided with coaxial through holes 10 for the passage of the sample 1. During the test, first pass the sample 1 through the through hole 10 of the aging box 11 , and then fi...

Abstract

The invention provides a device for testing the damp-heat aging of a composite material, which overcomes the technical defects of single heat factor aged equipment. According to the device, multi-station, mechanical and stress loading accelerated damp-heat aging test can be realized, and theoretical references are provided for the application of the composite material. The test device comprises an aging box, a sample clamping system, a balance adjusting system and a stress-strain measuring system, wherein the sample clamping system comprises a steel framework, a bolt, a clamp, a sample station and a pin shaft 3; and the balance adjusting system comprises a balance beam, a pin shaft 8 and a counterweight. According to the device, 1-10 samples can be tested simultaneously, the service temperature of equipment ranges from the room temperature to 300 DEG C, the loading force of every sample is 0.5-8 tons, and continuous 5,000 hours of constant-temperature test or thermal cycle test can be realized; and by adopting the sample clamping system, samples can be prevented from slipping and loosening under the action of eight-ton tension. The device has a simple structure and higher test efficiency than the conventional equipment, and the test conditions are more consistent to the practical working condition.

Description

technical field [0001] The invention belongs to damp-heat aging test equipment for resin-based composite materials, in particular to a damp-heat aging test device for composite materials. Background technique [0002] The interior of the carbon fiber composite core conductor is a uniform solidified core layer composed of carbon fiber and resin. The outer layer of the core layer is a hybrid fiber reinforced resin-based composite material cladding layer, and a series of round or trapezoidal aluminum wires are stranded on the outside. Compared with the existing steel-reinforced aluminum stranded wire, it has the characteristics of light weight, high strength, small thermal expansion coefficient, strong ice and snow resistance, high conductivity, double capacity transmission, land saving, corrosion resistance and long service life. . [0003] As a new type of wire, the service life of the carbon fiber composite core under the operating state of the line is an important basis fo...
