Mechanical properties of sisal fiber reinforced composites on surface treatment and temperature

There has been a growing interest for the use of natural fibers in composite applications due to their low cost, environmental friendliness, and good mechanical properties. It was demonstrated to determine the characteristic of tensile behaviors under the variation of test temperature on sisal fiber reinforced polymer composites by RTM process. Especially, the permanganate-treated-fibers improved tensile strength by increasing the coherence with matrix. Material deformation is restricted to increment of cohesion for surface treatment of fiber and then elongation decreased.
