On the morning of May 30th, Professor Niu Kangmin, a national special expert of University of Science and Technology Beijing, was invited by Professor Zhang Zuoqi and lecturer Yuan Yanan of our college to give a research seminar on the subject of “Nano-enhanced composites compression performance and mixing ratio”.

Before the lecture, Professor Zhang Zuoqi introduced Niu Kangmin's academic achievements and expressed warm welcome to his visit. In the lecture, Professor Niu Kangmin introduced the application of traditional composite materials in large aircraft. He pointed out that the compressive strength of high-performance fiber reinforced resin-based composites is much lower than the tensile strength, and the higher the fiber strength, the greater the difference. The main constraint mechanism of the compressive strength of the fiber reinforced resin-based composite is that the resin yields to form a shear band and causes the fiber to be slightly unstable. Finally, Professor Niu Kangmin believes that the emergence of new nano-enhancement technology will lead to a new generation of super fiber reinforced resin-based composite materials. In the questioning session, many teachers in the Department of Mechanics and Professor Niu Kangmin had a heated discussion on the development of multi-scale mechanics of composite materials.
