Relative Errors

Continuous fiber reinforced thermoplastic composites with advantages of high strength, long life, corrosion resistance, and green recyclability have been widely used in aerospace, transportation and high-precision processing equipment, etc. 3D printing is an advanced additive manufacturing technology that enables the rapid manufacture of complex structures and high-performance composites. The aim of this study is to evaluate the precision and stability of 3D printed continuous fiber reinforced thermoplastic composite structures and construct suitable mathematical models to predict tensile properties. Samples evaluated in this study were produced by varying the volume fraction and distribution mode (average and central mode) of fibers within the printed structures. The measured data proved the continuous fiber reduced the printing precision on width and thickness and the printing stability on thickness, while it improved the width stability in the XY horizontal plane. The printing precision and stability of samples with an average mode were slightly better than those of samples with a central mode. The tensile results of 3D printed continuous fiber reinforced thermoplastic composites demonstrated that an increasing volume of fiber reinforcement resulted in the increasing stiffness and ultimate strength of tested samples. The average elastic modulus and ultimate tensile strength of samples with the average mode were higher than those of samples with the central mode, while the average strain at break was quite the opposite. Mathematical models of elastic modulus were established to achieve the relative errors 0.06% and 2.14% for checked samples, while relative errors of the mixing rule were up to 76.15% and 81.71%, respectively. Some typical defects affecting the surface quality and the fracture behavior of 3D printed samples were researched by the analysis of micromorphology.

Monitoring Technologies

3D printed neat thermoplastic polymers (TPs) and continuous fiber-reinforced thermoplastic composites (CFRTPCs) by fused filament fabrication (FFF) are becoming attractive materials for numerous applications. However, the structure of these materials exhibits interfaces at different scales, engendering non-optimal mechanical properties. The first part of the review presents a description of these interfaces and highlights the different strategies to improve interfacial bonding. The actual knowledge on the structural aspects of the thermoplastic matrix is also summarized in this contribution with a focus on crystallization and orientation. The research to be tackled to further improve the structural properties of the 3D printed materials is identified. The second part of the review provides an overview of structural health monitoring technologies relying on the use of fiber Bragg grating sensors, strain gauge sensors and self-sensing. After a brief discussion on these three technologies, the needed research to further stimulate the development of FFF is identified. Finally, in the third part of this contribution the technology landscape of FFF processes for CFRTPCs is provided, including the future trends.
