Mechanical Properties ofPoly Lactic Acid:An Accelerated Destructive Degradation Test
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 9
Abstract
Research in renewable products with the potential to replace fossilized matter as raw materials for energy and materials use is at the forefront of modern science and engineering. Materials (i.e., Poly lactic acid) have been researched by industry and academia showing great interest in the degradation process typically represented by degradation models. The accuracy of these models is a complex task to accomplish. It requires the quantification of the degradation rate of the materials with different variables. In this paper, tensile testing is used to characterize the lifetime of PLA material. Over 60 specimens were manufactured under ASTM standard, followed by 2,000 hours of accelerated destructive degradation testing. The results demonstratea significant statistical effectin the mechanical properties of the material. The variables that made adifference on the degradation rate weretemperature, humidity rate, UV light.
