Abstract

Materials which offer the combination of high damping and stiffness are attractive for many industrial applications. In this work the stiffness and damping properties of POLYPROPYLENE/Calcium-Carbonate (PP/CaC03) NANOCOMPOSITEs have been studied. In order to improve the dispersion of CaC03 nanoparticles in POLYPROPYLENE matrix, nanoparticles were coated by monolayer of stearic acid. All samples containing 5, 10, 20 and 30 wt% nanoparticles were mixed in co-rotating twin screw extruder and were formed into sheet by hot press, then standard tensile specimen were provided by pneumatic punch. Tensile properties of samples were experimentally investigated. To examine DYNAMIC MECHANICAL PROPERTIES we use DMT A and Morphology of samples was performed bySEM. SEM images showed a suitable dispersion of coated CaC03 nanoparticles by monolayer of stearic acid. The results of tensile test showed that with growth of nanoparticles weight percent, tensile strength decreases and young's modulus increases. According to the results of DMTA, damping properties of samples improve with the growth of CaC03 nanoparticles.
