【 摘 要 】

In view of the strong chemical inertia and poor wettability of basalt fiber, its surface was treated by modified silica-carbon black particles. The surface roughness of basalt fiber was observed by scanning electron microscope (SEM). The change of fiber contact angle was measured. And the mechanical properties of fiber composites plate were tested. After the treatment, the results showed that the surface roughness of basalt fiber was increased and the wettability of the fiber was improved. The flexural properties and impact resistance of fiber reinforced unsaturated polyester resin were improved greatly. Compared with KH-570, the effect of KH-550 modified particles on basalt fiber was better than that of KH-570. Therefore, silica-carbon black as a modified particle to treat basalt fiber was a feasible solution.
