Abstract
Industries have been applying polymers in many different ways for decades, such as structural materials, cars and planes components, mechanical parts, etc. However, the polymeric materials exhibit viscoelastoplastic behavior meaning their properties vary as time goes by. In the case of high density polyethylene (HDPE), this behavior is non-linear viscoelastic and, therefore, the material properties also varying according to the applied tension level. One way to characterize the behavior of HDPE is by using uniaxial creep test. In this work, a device capable of performing creep tests was developed. For this purpose, PDP guidelines were followed in order to develop a equipment with high acceptance among its users. The test machine has been designed in CAD software and the manufacture of the componentes was made by using conventional and CNC machines. Each part of the device was made of stainless steel. After the setting, a potential signal acquisition system was provided. Finally, a creep test was performed to evaluate the efficiency of the device.
