Study of Tensile and Impact Properties for 0⁰ and 45⁰ Fiber Directional Orientation of Polyester Resin Composites with Woven Ramie Reinforced

Abstract

The current technological need is the use of eco-friendly and biodegradable composites. It seeks to increase the use of natural resources to engineer composite materials to be better than before. This study aims to analyze the effect of ramie fiber orientation for ramie composites (in this study 450 and 00) on tensile strength and impact strength and find the best orientation angle with higher power and impact value than the other fiber angles on ramie composite. The fiber used in this study was ramie fiber, and the matrix used was Yukalac 157 BQTN-EX polyester resin. This research method uses the experimental process of conducting experiments and testing. The results showed that the 00 angle direction composite achieved the highest average tensile strength value of 54.3 N/mm2, and the impact strength showed the highest average impact strength value of 0.0168 J/mm2, performed by the 00 composites.
