Abstract
In this study, the thermal properties of HDPE polymer composite materials with waste tungsten carbide (WC) powder has been investigated. This waste used as additive material is produced by the accumulation of particles of tungsten carbide used as cutting tool in the machining industry. In machining sector, a significant amount of cutting tool wastes are generated and re-use of these wastes is considered. This study covers the effects of tungsten carbide particles on the thermal properties of HDPE polymer matrix. This waste filler material up to 50 wt% were used in the matrix. Mechanical properties of composites such as tensile and flexural strengths additionally elastic and flexural modules were investigated. The crystallinity percentage, phase change temperatures and specific heat capacities of WC filled HDPE composites were performed by DSC. Viscoelastic properties such as storage modulus, loss modulus and damping factor of the composites as a function of temperature were evaluated by DMA. In addition, thermal conductivity of the composites were investigated.
