Description

technical field

[0001] The invention relates to a polypropylene composite material, in particular to a homopolypropylene / carbon fiber / montmorillonite composite material and a preparation method thereof. Background technique

[0002] In the first ten years of the 21st century, the research and development of new energy and new materials in China and other economies around the world have reached a new and higher level. The development of the material field provides a new starting point, a new opportunity, and the requirements for polymers tend to be multi-functional. In the 1980s, the new technology of micro-foaming polymers proposed by the Massachusetts Institute of Technology has significantly improved the performance of materials. At the same time, endowing polymers with excellent new properties has become a new field and new direction for many researchers. Generally speaking, the diameter of microcellular foamed materials is relatively small, about 1 μm to 100 μm. The hol...
