Abstract Scope |
Fiber-reinforced additive manufacturing (FRAM) has become quite popular in several industries. The technology offers an opportunity to improve the existing mechanical performance of the part. This research study has presented the successful methodology to fabricate the FRAM-based composite parts with improved fatigue properties. Most engineering applications are subjected to cycling loading which makes the fatigue study an important analysis. The scope of this paper is to present the fatigue properties of short carbon fiber (13.78% by weight)-reinforced Polyethylene Terephthalate Glycol (SCFs/PETG). The fatigue behavior was analyzed by varying the 3D printing process parameters i.e., infill orientation (00, 450, and 900), and infill layer heights (0.2 and 0.3 mm). The tests are carried out on 1600N as a maximum load of fatigue cycle with a 0.1 stress ratio, for the specimens with 900 and 450 orientations with 0.2- and 0.3-mm layer heights. For 00 orientation, both 0.2- and 0.3-mm layer heights specimens are applied to 2600N as maximum load, keeping the stress ratio the same as 0.1. Analysis of Variance (ANOVA) is used to statistically analyze the testing data to understand the influence of input variables on fatigue properties. |
