Starch acetate N-fibre composites

Cellulosic fibre composite compounds based on hemp and flax fibres in triethyl citrate plasticised starch acetate were prepared by melt processing. Composites were prepared with fibre contents up to 50w%. A stiffness of 8.3 GPa and stress at maximum load of 51 MPa were obtained with 40w% flax fibre in a plasticised starch acetate with 20w% triethyl citrate. An almost linear relation between fibre content and the tensile properties was found. The impact strength of the composites was increased with the plasticiser content. The porosity content was low even at high fibre content.Godkänd; 2008; Bibliografisk uppgift: USB; 20081010 (joffe
