Abstract

In this paper, several space environmental simulation tests, including particle irradiation and thermal cycling were carried out on the Diamond/Cu composites. The properties and microstructure of composites before and after different environmental effects were compared. The results show that the thermal conductivity of the composites is above 600 W/mK and the change amplitude is less than 5% after the space environment simulation tests. The bending strength is higher than 400 MPa after space environmental simulation tests, and the bending strength is increased by about 15% after particle irradiation. After the space environment test, the Diamond/Cu composite still maintains good thermal physical properties and mechanical properties, which meet the requirements of the space environment.
