Abstract: Non biodegradability in environment, sophisticated method of fabrication and economical soundness of synthetic fibers makes its alternative source for preparation of other composite from environmentally eco friendly materials. Many bio-based agricultural waste materials having very low environmental impact can be used in different scientific applications than manmade synthetic materials. Sugarcane is a renewable, natural agricultural resource which can be use in many products for major scientific applications after extraction of juice. Ultrasonically determined blended aqueous solution of NaOH is used for the surface modification of the dried fibres. The SEM characterization of treated fibre and the bio composite prepared from suitable composition of epoxy resin as matrix and sugarcane as filler confirm the suitability of the material for thermal, electrical and sound absorption property. Measurement of electrical and thermal conductivity of the sample indicates the insulating behavior of the sample. The dielectric constant of the material decreases with increase of log frequency indicating its energy storage performance. The presence of more porosity in network structure improves the sound absorption coefficient computed from the data obtained experimentally.
