EFFECT OF THE BF'S SURFACE MODIFICATION ON BF/BAMBOO/WOOD COMPOSITE'S BONDING PROPERTIES

Abstract

Abstract: Bonding performance of wood composite material is important parameters in the use of wood composite structural material. In this study, in oder to reinforce the bonding properties of BF/bamboo/wood composite, we use silane coupling agent KH550, plasma (PL), maleic anhydride (MA), salt ester etching (AE) and a combination of the above methods to modify the basalt fiber surface.The results showed the combination treatment on reinforcing the surface of basalt fiber has a better prefermance, and the order of effecting the BF/bamboo/wood composite bonding properties is as follows: MA550>PL550>AE550>KH550. After the KH550 and maleic anhydride-grafted combination treatment, the shear strength of bamboo-fiber layer reached 8.64 MPa, and the shear strength of wood-fiber layer reached 8.47 MPa; MA550 combination treatment increased by 50.45% than individual KH550 treatment, whereas wood-fiber glue had no fiber release.

Key words: basalt fiber, composite materials, maleic anhydride, bonding properities
