Abstract

Lightweight and high-strength metal matrix composites can meet structural lightweight and performance requirements, and are irreplaceable key basic materials in high-tech fields. In this Salon, we will consider how to solve major national problems and lead the frontier of international disciplines from the perspective of traditional research fields.Firstly, we will introduce the development experience of new composite materials, and take specific key technologies as an example to explain how to break through some "neck" core key bottlenecks, break the international blockade, and achieve breakthroughs in various spaceflight models. In order to further deepen the research on configurational composites, taking advantage of the diversity of biological configurations and their unique structural effects, a new concept of "Morphology Materials" was proposed, a new composite construction method adhering to the natural subtle configuration was established, a series of new materials with biological fine configuration were created, a new phenomenon of configuration component coupling was found, and the structure-activity mechanism was revealed, It provides a new method for the study of  configurational  recombination.
