Influence of interfacial bond strength on the mechanical properties of resin mineral composite reinforced by molybdenum fibers

摘要

To improve the poor mechanical properties of resin mineral composite, molybdenum fibers reinforced technology and mechanism are researched. The micro-surface morphology of new and wire electrical discharge machining used molybdenum fibers are analyzed, and the cohesive reinforce mechanism is deduced respectively. Two-dimensional simplified finite element model of resin mineral composite reinforced by molybdenum fibers is established for the simulation analysis of bond-slip of interface between fiber and resin matrix. Tests on the internal stress distribution of resin mineral composite without fibers and resin mineral composite reinforced by molybdenum fibers are carried out. Research results show that the addition of molybdenum fibers can effectively restrict the deformation of composite, and the randomly distributed pits on the surface of wire electrical discharge machining used molybdenum fibers can enhance the strengthening effect and reduce the cost of composite.
