Abstract

Dynamic mechanical properties of polymer blend composites reinforced with flax woven were investigated. Polyurethane prepolymer was used as a modifier with the varied composition of 5–20 wt% within the epoxy resin. The ultrasonic stirring process was employed to mix the polyurethane with epoxy resin. Polymer blend composite was fabricated by using hand layup technique followed compression pressing. Tensile and flexural test was carried out for the fabricated composite. Experimental results revealed that the increasing polyurethane composition gradually decreases the mechanical properties of the blended polymer composite. Additionally, polyurethane blending has reduced the brittleness of composites. Dynamic mechanical properties of fabricated blend composites like storage modulus, loss modulus, and loss factor (tan δ) were improved only with 10% polyurethane composition.
