Abstract
Dynamic mechanical analysis (DMA) was used to characterize biomedical composites consisting of synthetic hydroxyapatite (HA) particulate reinforced polyethylene (PE). The effects of the HA volume fraction, temperature and HA particle on the storage modulus (E I) and damping (tan δ) were investigated. Increasing HA volume fractions increased E I and decreased tan δ. E I was found to be linearly related to the Young's modulus values obtained from quasi-static tensile tests. Relative modulus and damping studies showed that the viscoelastic behavior of unfilled PE was different to that of the filled matrix due to the presence of thermally induced tensile stresses in the matrix at the filler-matrix interface.
