This paper contains the results of test on the development of impact properties of GFRP and CFRP by using basalt fiber. The hybrid composites used in the experiment were produced by using the vacuum assisted resin transfer molding(VARTM) process. The composite materials formed by laminating 20 plies of fiber. For this study, five kinds of glass-basalt/epoxy interfly hybrid composite(GBG, BGB, GBGBG, BG and GB) and five kinds of carbon-basalt/epoxy interply hybrid composite(CBC, BCB, CBCBC, CB and BC) were made. On addition, for comparison, GFRP, CFPR and BFRP were produced. At first, the effect of stacking sequences of basalt fiber on impact properties of the composites was investigated and then, the variation of the properties of them in accordance with the increment of basalt fiber contests. The experiments were conducted in accordance with ISO-179. Absorbed impact energy, deflection and impact strength were obtained through Charpy impact test. When glass fiber was combined with basalt fiber, impact properties were improved up to the level of the BFRP. Especially, when basalt fibers were arranged in impacted side(BG), the composite showed the best impact properties. At was also seen that the impact properties of the hybrid composite were improved by a combination of glass and basalt fiber. Especially, when basalt fibers were arranged in impacted opposite side(CB), the composite showed the best impact properties. For the BG and CB type of hybrid composite showed the best impact properties, the variation of the propertied according to the content of the basalt fiber were investigated. In the case of BG, the higher amount of basalt fiber, the higher impact properties were obtained. This can be made in quadratic equation. On the other hand, the impact properties of BC was improved until 20% of basalt fiber, but when the basalt fiber was 20% or more, almost no change in properties.
Through this study, it was found that the production of low-cost, high efficiency and environmentally friendly hybrid composites are possible by a combination of basalt and carbon or glass fiber.
