Abstract

With the aim of developing a technology for explosive pressing of powder composite mixtures of ultra-high molecular weight polyethylene (UHMWPE) with inorganic fillers, the thermomechanical properties and structure of a composite containing 5% β-sialon after static and explosive pressing were investigated. It was found that explosive pressing with a pressure of 0.75 GPa provides a composite heat resistance close to that of the initial UHMWPE (142-148 °C), reducing its thermal deformation expansion, which is associated with an increase in intermolecular as well as adhesive interaction at the phase boundary. During sintering, the polymer matrix is monolithized, and higher heat resistance is achieved after sintering under pressure. The research results allow us to recommend a method of explosive pressing for industrial processing of a composite mixture of UHMWPE + 5% β-sialon.
