Experimental investigation on neem fiber/epoxy composites
Containing with and without NaoH treatment

In this paper investigates the mechanical characteristics of natural (neem) fibers/epoxy composites with and without NaOH treatment. The neem fiber specimens were fabricated by use of wet lay-up method, it’s containing a polymer matrix, neem fiber, with and without NaOH treatment. Bending (flexural) strength, impact toughness (strength), and tensile properties were tested on neem fiber reinforced matrix composites with maximum loading and various weights percentage of NaOH (1, 1.5, 2, and 2.5wt%). The results showed that by altering the fiber content, with NaOH (2%). treated neem fibered composite's properties enhanced in comparison to the untreated fibered composite.
