In this thesis, a comprehensive study is conducted on mechanical, thermal and structural properties of Continuous Fiber Reinforced Additively Manufactured (CFRAM) components. CFRAM components are lightweight, yet strong materials with a wide range of potential applications in the automotive industry, aerospace, sports goods, and medical tools. The wide range of applications of these novel materials justifies the need to study their mechanical and thermal properties. CFRAM parts are lightweight compared with metals, have strong mechanical properties, have easy process, and short manufacturing time. In addition, thermoplastic polymers used for CFRAM components make the products recyclable. In this study, fiber reinforced composite specimens were printed using a commercially available printer and their mechanical, thermal and structural properties were investigated. Nylon and onyx were used as the matrix and Carbon fiber (CF), fiberglass (FG), and Kevlar were used as reinforcing agents. Mechanical and thermal analyses include tensile analysis, creep analysis, Dynamic Mechanical Analysis (DMA), Thermogravimetric analysis (TGA), thermal conductivity, heat capacity, and heat diffusion. Also, the effect of fiber type, fiber content, infill density, infill pattern, matrix type, layer thickness, printing orientation, and temperatures on thermomechanical properties were investigated. Microstructural analysis was conducted to investigate the fracture mechanism, internal morphology, interlayer adhesion, and the printing quality of specimens. For this aim, optical microscope and SEM analysis were used. The analytical and statistical analyses were conducted to study tensile strength, and creep properties of CFRAM components. The rule of mixture was used to study the tensile properties, and the linear regression analysis was used to analyze the creep properties. Finally, the applicability of CFRAM components for fabricating automotive parts was examined. For this aim, ease of design and manufacturing, final price, and production time as three important manufacturing factors were considered. Three car parts including thermostat housing, oil breather cap, and timing cover were printed and their properties were compared with metal parts produced with traditional methods.
