dc.description.abstractThe objective of this study was to investigate the effect of the addition of the colemanite having 45µm size on the significantcharacteristic features of the isotactic polypropylene (IPP). The microstructural properties (diffraction pattern, a,b and c unitcell parameters and grain size) and mechanical behaviors (tensile strength, Young's Modulus, impact strength and percentelongation of the samples relative to the colemanite content (5, 10, 15, 20 and 30 wt.%) were studied in details. The optimumamount of colemanite was determined in order to obtain IPP based composites having improved properties. The obtainedsamples were characterized by using XRD and conventional mechanical tests. The results showed that the content level of thecolemanite considerably affected the fundamental properties of IPP. As for microstuructural properties, it was observed fromthe XRD patterns that all composite samples mainly showed only ? form (monoclinic arrangement) in the crystalline domainswithout any ? form (hexagonal arrangements). Moreover, the finding revealed that a and b the unit cell parameters of IPPbased composites increased initially, reached the maximum values with the products containing 10% of colemanite, and thenthe consistent decrement trend was observed with the further increase in the colemanite content in the products. Conversely, cunit cell parameter almost remained relatively unchanged. Furthermore, the mechanical test measurements depicted that thereinforcements were achieved in the tensile, Modulus and impact strengths of the composite materials, while the percentelongation of the products decreased with the increasing of the colemanite content. 7.4%, 24.9% and 6.7% increases wererecorded in the tensile strength, Modulus and impact strength at the product with 10% colemanite, respectively. Theimprovements were probably stemmed from that the presence of micro size colemanite particles gave rise to increment in theorientations and alignments of IPP chain in the matrix.en_US
