Effect of Clay Addition on Mechanical Properties of Unsaturated Polyester/Glass Fiber Composites
Unsaturated polyester (UP)/glass fiber/clay composites were prepared by hand layup method. The effect of clay loading on the
morphological and mechanical properties of UP/glass fiber composites was investigated in this study. X-ray diffraction (XRD) was
used to characterize the structure of the composites. The mechanical properties of the composites were determined by tensile,
flexural, unnotched Charpy impact and fracture toughness tests. XRD results indicated that the exfoliated structure was found in
the composite containing 2 wt% of clay while the intercalated structure was obtained in the composite with 6 wt% of clay.Thetensile
strength, flexural strength, and flexural modulus of the composites were increased in the presence of clay. The optimum loading of
clay in the UP/glass fiber composites was attained at 2wt%, where the improvement in in tensile strength, flexural strength, and
flexural modulus was approximately 13, 21, and 11%, respectively. On the other hand, the highest values in impact toughness and
fracture toughness were observed in the composites with 4wt% of clay

Mechanical, Thermal and Morphological Properties of Injection Molded Poly(lactic acid)/Calcium Carbonate Nanocomposites
In this work, mechanical and thermal properties of maleated ethylene-propylene rubber (EPR-g-MAH) toughened poly(lactic acid) (PLA)/nano-precipitated calcium carbonate (NPCC) nanocomposites were investigated. It was found that elongation at break of PLA/NPCC was increased with increasing EPR-g-MAH content up to 15 phr (parts per hundred resin). The investigations on the crystallization behaviours demonstrated that the NPCC acted as nucleating agent for the PLA. However, the degree of crystallinity of PLA was reduced by the addition of EPR-g-MAH which appears to be due to encapsulation of NPCC by the maleated rubber. Dispersion of NPCC was observed using transmission electron microscopy (TEM), and it was revealed that both nano-dispersed and agglomerates NPCC exist in the PLA matrix. Moreover, encapsulation of NPCC was favored in the presence of EPR-g-MAH

Characterisation of Water Absorption of Biodegradable Poly(lactic Acid)/Halloysite Nanotube Nanocomposites at Different Temperatures
Poly(lactic acid) (PLA)/6 wt% halloysite nanotube (HNT) nanocomposites
were prepared using melt compounding followed by compression molding. Two types of
impact modifiers, i.e., maleic anhydride grafted styrene-ethylene/butylene-styrene
copolymer (SEBS-g-MA) and N,N'-ethylenebis(stearamide) (EBS) were used to toughen
the PLA nanocomposites. The effects of water absorption on the thermal and impact
properties of PLA/HNT at three different temperatures (i.e. 30°C, 40°C and 50°C) were
investigated. The diffusion coefficient (D) of PLA was decreased by the incorporation of
HNT and impact modifiers. It was found that the activation energy of water absorption
(Ea) of PLA/HNT6/EBS is higher than that of PLA/HNT6/SEBS-g-MA nanocomposites.
The reduction of impact strength, glass transition temperature (Tg), cold-crystallisation
temperature (Tcc), and melting temperature (Tm) of the PLA samples is attributed to the
hydrolytic degradation of PLA
