会议名称：46th LEEDS-LYON SYMPOSIUM ON TRIBOLOGY

会议时间：2-4 Sept 2019

会议地点：Lyon, France

会议简介：

The symposia are jointly sponsored by the University of Leeds (UK) and the Institute National des Sciences Appliques (INSA) de Lyon, University de Lyon (France).  The inaugural symposium was held in 1974 and since then there has been an annual meeting in the month of September, the sponsoring Institutions acting as hosts on alternate occasions.  After 46 successful events, the symposium has become an established event in the international tribology calendar.  Each year the symposium provides an opportunity to tribology and those working in related fields to discuss and assimilate recent advances of tribology and to exchange views and ideas on a broader basis. Combining both breadth and depth the symposium will provide an outstanding forum to review recent advances in tribology and applied surface science and to examine the contribution these areas can make to a sustainable future.

Abstract: Polymer composites reinforced with aligned nano-particles have attracted much research interests due to its excellent mechanical and tribological properties by make full use of anisotropy of nano-particle. The CNTs@Fe3O4 hybrids have been prepared by modified co-precipitation method and aligned in carbon fabrics/epoxy composites at thickness direction using a weak magnetic field to simultaneously improve the mechanical and tribological properties. The research results have shown that modified co-precipitation method can synthesize Fe3O4 nano-particles in smaller size (less than 10 nm in diameter) compared conventional co-precipitation method (20-30 nm in diameter) and the achieved the better dispersity in solution, promoting more Fe3O4 nano-particles attached to the surfaces of CNTs. The interlaminar shear strength and hardness of composites containing aligned CNTs@Fe3O4 achieved significantly improvement because of the presence of CNTs along thickness direction of composites, compared to those containing randomly distributed CNTs@Fe3O4. And the lubricating property and wear resistance of composites containing aligned CNTs@Fe3O4 achieved significantly improvement, particularly under high applied load, compared to the composites containing randomly distributed CNTs@Fe3O4, which mainly use of the friction anisotropy of CNTs.
