(197d) Thermo-Mechanical Properties of 3-D Printed Fiber Reinforced Nylon Composites

Among various production techniques, 3-D printing is an emerging field in industry, because it reduces the design time and improves flexibility of tooling for customization. Printing of composites, that is fiber-filled polymers, using fused deposition modeling, is an important thrust. In this regards, studying thermo-mechanical properties of printed composites based on engineering polymers is important to such areas as aerospace and automotive. In this study, nylon polyamide was 3-D printed using three different fibers containing carbon fiber (CF), fiber glass and Kevlar. Dynamic mechanical analysis (DMA) and creep was used to characterize mechanical response of the specimens at different temperatures. Temperatures of up to 100^o C were included in the matrix.
