Abstract:
The additive manufacturing of continuously fiber reinforced thermoplastic composites offers new opportunities to enhance the mechanical properties of these materials. This study investigates the mechanical properties of continuously fiber reinforced ULTEM 9085 materials produced by additive manufacturing. The primary objective is to analyze the effects of different fiber ratios and printing parameters on the mechanical performance of these materials. The study experimentally examines the tensile, flexural, and impact mechanical properties. Using the Taguchi method and ANOVA, the parameters with the highest impact on the outcomes were identified. The ULTEM 9085 material and continuous carbon fiber reinforcement used in this study are materials with high potential for aerospace and aviation applications. The study also addresses production times and costs, which are critical for these sectors. The findings contribute to the optimization of additive manufacturing processes for producing high-performance fiber-reinforced thermoplastic composites. Compared to traditional composite materials, which often use high fiber ratios, this study observed significant improvements with fiber volume ratios ranging from 3% to 10%. Specifically, tensile strength increased by 2 times, flexural strength by 1.5 times, and impact resistance by 3.5 times. These insights are particularly valuable for industries such as aerospace and automotive, where material performance is critical. In conclusion, this research demonstrates that additive manufacturing can produce continuously fiber reinforced thermoplastic composites with superior mechanical properties using optimized parameters. Future studies will focus on exploring the long-term durability and environmental impacts of these materials, aiming to further enhance their applicability in various high-demand sectors.
