Characterisation and optimisation of mechanical, physical and thermal properties of short abaca (musa textile nee) fibre reinforced high impact polystyrene composites
Published 2011“…In this research, glass transitions temperature (Tg) of neat HIPS occurred below the Tg of optimum condition of composites as the temperature of an amorphous state. The endothermic peak of composites was in the range of 430 0C – 435 0C including neat HIPS and it was observed that enthalpy of abaca fibre reinforced HIPS composites was yielded below the enthalpy of neat HIPS of 748.79 J/g. …”
