| Summary: | 碩士 === 桃園創新技術學院 === 材料應用科技研究所 === 100 === This study, first, the basalt fibers have carried on the surface treatment by the A-174 silane coupling agent of different concentration, then drying, and that into the woven roving of plain structure prepared by weaving with using the fabric design proofer. The woven roving of basalt textile fiber mixed with the unsaturated polyester resin and formed the basalt fiber reinforced plastics（FRP） of plate-type. Then, we discussed that the relation of tensile strength, the impact strength and the bending strength of GFRP with the coupling agent concentration and the fineness of basalt fiber, and also observed its interfacial failure structure by the scanning electronic microscope.
The experimental results showed that when the coupling agent concentration increases, the tensile strength of basalt fiber reinforced plastics（FRP） of plate-type also increases. Another, we found that the influence of coupling agent concentration to the impact strength and bending strength of FRP is the same as that of tensile strength. Moreover, we also found that when the fineness of basalt fiber is smaller, the tensile strength, the impact strength and the bending strength of its FRP of plate-type is better. A fiber-matrix coupling effect can be observed in which the interfacial fracture of basalt fiber reinforced unsaturated polyester resin by scanning electron microscope. We found that the fiber surface of without coupling agent treatment which have pulled out is clean and there is not resin adhesion. After that of treatment with A-174 coupling agent, the absence of clear fiber surface impressions in the matrix.
