Cavitation in high density polyethylene/Al2O3 nanocomposites
Source abstract
Abstract
Abstract In the paper the cavitation phenomenon during tensile deformation of high density polyethylene/Al2O3 nanocomposites was analyzed. The influence of solidification process, filler content and diameter of its particles on the structure of HDPE/Al2O3 nanocomposites was described. Two different types of cavitation, i.e.: interlamellar cavitation of polymer matrix and cavitation around filler particles (by debonding), were identified. In the case of fast solidified nanocomposites interlamellar cavitation was suppressed. High intensity of the cavitation by debonding was related to the numerosity of small particles, as compared to the cavitation by large particles at similar weight concentration. Finally, the influence of different cavitation types on the intensity of fragmentation of lamellar crystals was presented.
