Abstract

The interest in natural fiber-reinforced polymer composite materials is rapidly growing both in terms of their industrial applications and fundamental research. The natural fiber composites are more environmentally friendly. The main objective of this project is to investigate effect of chemical treatment and addition of chalk powder (additive) to the composite on thermal and mechanical properties of (Palmyra bract fiber) natural fiber reinforced polyester composites. The composites have been made by with and without chemical treatment to Palmyra fiber and addition of chalk powder to the polyester matrix. Mechanical properties such as tensile properties (such as tensile strength, tensile modulus), Flexural properties (such as Flexural Strength, Flexural Modulus), Impact Strength when subjected to varying weights of fiber (0.5, 1, 1.5, 2, 2.5 grams) and thermal properties such as conductivity, specific Heat capacity, thermal diffusivity of composites are studied.The tensile strength, flexural strength, impact strength of chemical treated fiber composite increased when compared with untreated fiber composite by increasing fiber content. Thermal properties of treated fiber composite also increased when compared with untreated fiber composite. With addition of chalk powder to the treated composite Thermal conductivity, Specific Heat capacity, Thermal diffusivity of the composite are increased. But mechanical properties almost equal when compared to without addition of chalk powder to the composite.
