Effects of talc and gamma irradiation on mechanical properties and morphology of isotactic polypropylene/talc composites

Effect of temperature and pressure of hot pressing on the mechanical properties of PP–HA bio-composites

“…According to Di Silvio et al [9] who studied a composite polyethylene/hydroxyapatite with high mechanical properties and biocompatibility, increasing the volume fraction of HA increases the Young's modulus and tensile strength. The radiation process can be a way to modify the molecular structure of the polymer as an alternative to the traditional chemical methods [10]. Ramirez et al investigated the effect of radiation on the mechanical, thermal, rheological, and morphological behavior of polypropylene (PP) and PP-20% HA and 30% HA composites [11].…”

Weathering properties of coextruded polypropylene-based composites containing inorganic pigments

“…11. The elongation at break of all the composites is relatively low (less than 1%), compared to the elongation at break 45% for the pure polypropylene [22]. Such low values can be explained by the presence of fillers.…”

“…Such low values can be explained by the presence of fillers. Denac et al [22] showed that the incorporation of 12% talc to the polypropylene matrix decreased the elongation at break from 45% to 2%. After weathering, the elongation at break was reduced for all the composites, except for the composite containing zinc oxide, which retained its elongation at break.…”

Preparation and Preliminary Study on Irradiated and Thermally Treated Polypropylene (PP) - Styrene Butadiene Rubber (SBR) Composite

“…The radiation polymerization has received a great attention from a large number of investigators. It can modify the molecular structure of the polymer as an alternative to traditional methods [9]. Gamma radiation is commonly used as its penetration technique is simple, fast and very effective without significant variation on crystallinity and glass transition temperature.…”
