Abstract

The invention discloses a preparation method for enhancing interface performance of basalt. Firstly, a PAN-basalt nano-coated fiber is prepared by using the electrospinning technology; then the prepared PAN-basalt nano-coated fiber is carbonized to obtain a core-structured basalt carbonized nano-material with enhanced interface performance; finally the prepared core-structured basalt carbonized nano-material and resin matrix are solidified to form a composite with enhanced interface performance. The composite has the advantages of a large surface area, relatively high electrical conductivity,complete structure and good absorption performance of a cortical carbon nano-material, excellent mechanical properties of a core layer basalt fiber, and can simultaneously exert the advantages of thetwo materials. The preparation method for enhancing the interface performance of the basalt has the advantages that less pollution to environment is generated, can be widely applied to the field of fiber reinforcement materials, and solves the problem of poor interfacial adhesion of the basalt fiber reinforced resin matrix composites in the prior art, further optimizes the performance of the composites, and can promote design of the new fiber composites, which facilitates better application and development.
