Bio-composite materials have numerous advantages,such as low cost,low density,high toughness,acceptable specific strength properties,ease of separation and biodegradability.However,the bio-composite properties are degraded due to the weak interfacial bonding between the hydrophobic substrate polymer and hydrophilic biodegradable filler.The wax component and lignin,hemicellulose etc.,adversely affect the interfacial bonding between the matrixes.Modifications of bamboo and rice husk surfaces by chemical treatment and coupling agents were carried out in order to study the effects of these on the surface functional group properties and performances of bio-composite.Chemical modification of bamboo fibers and rice husk by NaOH,Acetic acid,and Silane improved the adhesion properties.The bamboo composite is the mechanical properties of PP80/PP20 composite was highest tensile and flexural strength in consider of specific gravity in glass fiber was shown similar or outstanding properties.Also the tensile strength,flexural strength and flexural modulus improved with increasing coupling agent content.This result indicated that an optimum level of the MAPP was 3PHR.The Rice husk mechanical properties of PP60/RH40 composite were highest tensile and flexural modulus improved with increasing coupling agent content.This result indicated that an optimum level of the MAPP was 5PHR.
