The effects of Vetiver fiber length on the mechanical properties of Root Vetiver fiber/epoxy resin composite were investigated. Five different samples were produced by varying the length of the fiber 3, 5, 7, 9 and 13 mm at 12% wt. fiber loading using the hand lay-up moulding technique. The tensile strength, tensile modulus, percent elongation, flexural strength, flexural modulus, impact strength of the composite were analysed.
The results showed that the tensile strength, flexural strength and impact strength increased with increase fiber length. However, the tensile strength, tensile modulus and percent elongation had their highest values of 26.08 MPa, 729.9 MPa and 5.56 % respectively at 13 mm fiber length suggesting critical fiber length for effective and maximum stress transfer. The impact energy at failure had their highest values of
20.154 KJ/m2 at 13 mm fiber length.
