The purpose of this study makes the basalt fiber reinforced composite and progresses the friction and wear property test. Because basalt fiber reinforced composite can be supplemented the defect like the harmfulness to human body and environmental damage of the glass fiber and overcome the defect that the application area is limited due to the high cost of carbon fiber. First, the test specimen was made with the optimized method according to the composites molding process. And the friction and wear property test result by the fiber orientation angle was analyzed. In addition, the friction section was analyzed. Finally, the friction and wear property test according to PTFE coating treatment of the material surface was compared and analyzed. This study verified the possibility of life extension caused by excellent wear resistance and enlargement of application area according to the low cost. And also, this study considered that the fiber orientation and the existence and nonexistence of the PTFE have a effect on tribological property.
The experiment was classified as three condition and progressed through the process method, fiber orientation, and PTFE coating treatment. VaRTM and Prepreg process method were compared. The tribological characteristics test according to the fiber orientation was progressed with prepreg fiber in Case1(0°), Case2(0°/90°), Case3 (0°/±45°/90°) of order. In addition, the tribological characteristics according to existence and nonexistence of PTFE coating treatment were analyzed through the experiment. Finally, the friction section worn away was observed through SEM.
Consequently, the test specimen which was made by using the prepreg process is shown the excellent tribological characteristic rather than the VaRTM process. And as to the tribological characteristic according to the fiber orientation, Case1 was the most excellent. Finally, in case of processing PTFE coating treatment, the coefficient of friction which about 0.18μ is low was measured.
This study result about friction and wear of the basalt fiber reinforced composite by PTFE coating can be served as base line data for the tribology application of the fiber reinforced composite.
