Abstract
Due to its low price and high mechanical property, basalt fiber (BF) is emerging as a novel reinforcement for fiber reinforced polymer (FRP) instead of glass fiber. The research about basalt fiber reinforced composites (BFRP) is insufficient in particularly for the long term life. Therefore, in order to apply BFRP into practical use, the current study was focused on mechanical property and their durable property. Firstly, one layer and six layers laminated unidirectional basalt fiber fabric reinforced unsaturated polyester were made by hand-layup method and tested by tensile, 3-point bending, short span bending and drill hole experiments. On the other hand, for the unidirectional basalt fiber fabric reinforced epoxy which are expected to be used in civil engineering, water and alkali solution immersion at various temperatures were carried out. The evolution of the mechanical properties along with ageing time was investigated. The results indicate that it is needed to improve the interface property between basalt fiber and polymer through surface treatment for enhanced durability performance.
