Speech Title: Design and Mechanical Behaviors of Carbon Fiber Composite Honeycomb Sandwich Structure
Abstract: The design objectives of spacecraft probe structure are to reduce the structure weight, improve the loading efficiency and ensure the profile accuracy. The satellite circularly enters the shadow area and the light area, where surface temperatures are between -180℃ and 120℃. It causes serious thermal deformation of the satellite antenna reflector, thus reducing the satellite detection ability. Carbon fiber composite honeycomb structure has the advantages of light weight, high specific stiffness, high specific strength and low thermal expansion coefficient. It has important applications in advanced spacecraft components such as satellite antenna reflector, space telescope and high precision optical support platform. This presentation introduces advanced progress made by our research group in the field of carbon fiber composite honeycomb structure technology, including: (1) Manufacturing technology of carbon fiber reinforced composite honeycomb; (2) Mechanical characteristics and evaluation of carbon fiber reinforced composite honeycomb sandwich structure under typical loadings; (3) Structural design, debonding characteristics and strengthening mechanics of interface-reinforced composite honeycomb structure; (4) Flexible design and mechanical characteristics of composite honeycomb structure.
