Abstract

The problem of this study is the unknown fatigue life (N) prediction of polymer materials, especially plastic specimens made from polypropylene (PP), low density polyethylene mixed with scrap (low density polyethylene/LDPE + 70% scrap), high impact polystyrene (HIPS), acrylonitrile butadiene styrene (ABS), and polystyrene (PS). The aim of the research was to obtain predictions of N from fatigue test results for 5 types of materials, PP, LDPE + 70% scrap, HIPS, ABS, and PS. The research method includes making injection molds for fatigue test specimens according to standard shapes and dimensions, injection molding, specimen preparation, fatigue testing using an integrated rotating bending fatigue testing machine (IRBFTM), analysis of fatigue test results in the form of a bending stress curve (S) to the fatigue life (N). The results of the fatigue test show that the N at 2200 rpm speed testing for PP materials in the range S 70 to 230 MPa is achieved at 15 x10⁵ Cycles, HIPS is 18 x10⁴ Cycles, ABS is 12 x10⁵ Cycles, and PS materials is 16 x10⁴ Cycles, and the LDPE specimen materials mixed with its 70% scrap cannot be tested for fatigue because they are very ductile or fatigue resistant.
