Resumen:
Polypropylene/woodflour composites with different fibre content were prepared
by intensive mixing and compression moulding. The effect of fibre content and the
incorporation of maleic anhydride grafted polypropylene (MAPP) on the materials
mechanical behaviour was investigated. An increase in Young´s modulus was obtained with
the addition of woodflour to PP, whereas tensile strength, strain at break and fracture
toughness were found to decrease as fibre content increased. The presence of MAPP was
slightly detrimental to the material stiffness but beneficial to tensile strength and had no
significant effect on ductility or toughness. Although reduced ductility and toughness were
observed for the composites, environmentally friendly materials were obtained with a
reduction in the amount of non-biodegradable material and also with a cost reduction without
sacrificing stiffness or strength.
