dc.description.abstractIn this work, calcite (KS) mineral was compounded with poly (lactic acid) (PLA) at the concentrations of 5, 10, 15 and 20 wt% using extrusion process. Test samples of PLA and composites were prepared by injection molding. Characterization of composites were done based on mechanical tests including tensile, hardness and impact tests, flow behavior by melt flow rate test (MFR) and morphological studies by scanning electron microscopy (SEM) method. Mechanical test results showed that the highest improvements in tensile strength and tensile modulus values were obtained for 10 wt% of KS filled composite. Further addition of KS caused remarkable decrease in tensile strength. Impact strength of PLA reduced by KS additions. The highest impact energy value was found in PLA-15 KS sample among composites. Hardness of neat PLA increased after KS inclusions. KS loaded PLA gave slightly higher MFR values compared to neat PLA. SEM micro-images of composites implied that KS particles dispersed homogeneously in PLA matrix at their lower loading ratio. Large agglomerates and poor dispersion were obtained for higher concentrations of KS since they favor particleparticle interactions. According to these results, concentrations of 10wt% and 15wt% were determined as suitable for calcite containing PLA composites.
