mechanical properties of the hybrid composite. Keywords : Basalt fiber, Pineapple Leaf fiber, Vacuum bagging, Alkali treatment, Mechanical properties. 1. Introduction In recent times natural fiber composites have got great attention due to their superior properties such as low cost, low density, pollution free and adequate mechanical properties.
The physical properties of basalt fiber compared with other inorganic fibers are listed in Table It can be seen that basalt fibers have better mechanical properties than glass fibers, and a little worse than carbon fibers. However, the maximum service temperature of basalt fiber is the highest.
