1. The bridging model, an elastic-plastic constitutive theory of composite materials, was created. It is the only theory that satisfies the consistency of internal stress calculations and is also the micro-mechanics theory with the highest accuracy in the "Worldwide Failure Assessment (WWFE)" evaluation (Comp. Sci. Tech., 64:565, 2004), and is the only participating theory that calculates thermal residual stresses in fibers and matrices (Comp. Sci. Tech., 64:450, 2004), has become a well-known theory in the world of composite material mechanics and has been widely used. More than 220 papers have been published by "other uses" at home and abroad; 2. Damage, failure and strength analysis of composite materials is The biggest challenge facing solid mechanics. Except for axial damage that may originate from fibers, other failures of composite materials all originate from the matrix. The key is that existing theories can only calculate the mean stress, and the analysis must be based on real stress. The true internal stress theory of the matrix created by him "from scratch" and "from 0 to 1" is a milestone in the maturity of the discipline of composite material mechanics; 3. Composite material damage usually results from interface cracking, and he completely solved the problem of when the interface between fiber and matrix cracks under arbitrary load. In addition to the properties of the fiber and matrix, it is only necessary to provide the transverse tensile strength of the composite material; 4. The aviation industry often regards composite materials as brittle materials. The lid is linear because of its axial and transverse stretching until failure, but it cannot explain why the shear nonlinear deformation is extremely significant. He revealed that the relative slip after cracking at the interface between fiber and matrix contributes the most to nonlinear shear deformation, followed by the influence of matrix plasticity and real internal stress; 5. People never understand: Why is the strength of carbon fiber significantly increased from T300 to T1100, but the compressive strength of the composite material along the fiber is almost unchanged? He revealed that when the fiber strength is high enough, the fiber deflection causes the matrix to shear failure under axial compression. Higher fiber strength does not help improve the axial compressive strength of the composite material, and can only be improved by reducing the eccentric arrangement of fibers and improving the shear strength of the matrix; 6. Delamination of laminates is the most common, and currently there are two major problems in predicting delamination: First, almost every loading step requires iteration, which requires extremely large calculations and cannot be used in projects; Second, there is no experimental standard for the determination of some input data. The layered initiation and expansion analysis method he established does not require any iteration. In addition to fiber and matrix properties, it only needs to provide the critical fracture toughness of unidirectional laminates; 7. For Hibert's 20th problem, a sufficient and necessary condition for the existence of solutions to general operator equations is established (Nonlinaer Analysis, Theory, Methods & Appl., 1989, 13:829 - 832); 8. He is the co-inventor of coaxial cospinning to prepare core-shell composite nanofibers, one of the three major technological advances in electrospinning (authorized invention patent number: ZL200310108130.9), which is better than foreign scholars published in Adv. Mater. The first article was published one month earlier.

He has published 4 monographs, 1 editor-in-chief, co-authored 8 chapters, and more than 230 journal papers, one of which has been cited by him in SCI more than 6700 times.
