The purpose of this lab is to
compare the mechanical properties of UHMWPE at two different
temperature conditions: 25°C (room temperature) and 75°C.
Because polymers generally exhibit different mechanical properties at
different temperatures, it is hypothesized that the elastic modulus,
ultimate stress and failure stress of UHMWPE will be significantly
different between the room and high temperature groups.
The material properties will be quantified by analyzing
force-displacement and stress-strain curves created for each specimen
at their respective temperature. The temperature difference will be
created using a heating apparatus specifically designed to heat and
maintain the specified temperature. A two-tailed t-test will be
performed on the three properties to support or reject the hypothesis.
