The integration of material design and additive manufacturing techniques holds significant research values for exploring new advanced materials and their potential applications. Composite materials, which possess remarkable characteristics such as exceptional strength, stiffness, lightweight structure, and resistance to high temperatures and corrosion, have been critical in driving the growth of the aerospace, railway transportation, automotive, marine, and robotics industries.The thesis consists of three main parts of research. The first part and second part focus on the tensile and flexural properties of 3D printed continuous carbon fiber reinforced composites with different volume fraction of carbon fibers. Experimental methods were employed to analyze the properties of continuous carbon fiber reinforced composites manufactured using 3D printing. The test data was compared to previous literature data and the given datasheet. The findings revealed that, with the exception of the flexure strength and tensile strength of the composite with the highest volume fraction of carbon fibers, the other measured values, including the modulus, were significantly lower and approximately half of those presented in the provided datasheet.The third part of the research focuses on investigating the puncture impact behavior of 3D printed carbon fiber reinforced composites, with particular emphasis on the composite material known as Onyx. This material is composed of nylon and chopped carbon fibers and is widely utilized in 3D printing applications due to its remarkable strength, durability, and versatility across various industries such as aerospace, automotive, and mechanical devices. However, despite its extensive use in these industries, there is still limited knowledge regarding Onyx's puncture impact behavior in impact events. In light of this, the research examined the ability of the Onyx material to resist impact loading and its toughness under four different conditions: different infill patterns, infill densities, impact velocities, and temperatures. Experimental results indicated that the internal structure (infill pattern), infill density, impact velocity, and temperature all significantly influence the material's puncture impact properties. Furthermore, the study analyzed the failure mechanisms of the Onyx materials underdifferent conditions based on the standard ASTM D3763-18.
