###### Abstract
This study also included the assessment of the structural health monitoring capability via the use of quantum resistive strain sensors made up of carbon nanotubes filled epoxy nanocomposite embedded at the core of the glass fiber-epoxy composites [13]. While the electrical characterization is mentioned, the electrical conductivity is not included in this research [13]. Also, the coupled flexural-electrical evaluation of additively manufactured multifunctional composites at ambient temperature was not addressed [13]. Flexural properties were characterized using three-point bending tests on continuous carbon-fiber reinforced thermosetting composites prepared using the FDM AM technique [14]. The 3D printed thermosetting composites' flexural performance was found to be superior to similar 3D printed thermoplastic composites, and 3D printed short carbon fiber-reinforced composites in [14]. Coupled effects of the multifunctional properties such as flexural-electrical properties of the 3D printed multifunctional continous carbon fiber solid laminate composites were not addressed [14]. Monofunctional flexural strength test was conducted on a novel 3D printing-based fabrication process of continuous fiber reinforced thermoplastic composites in [15]. Continuous carbon fiber was chosen as a reinforcing phase and PLA filament was chosen as matrix, and both the continuous carbon fiber and the PLA filament were simultaneously fed into the FDM 3D printer to develop an integrated continuous fiber reinforced thermoplastic composites [15]. The process parameters on temperature and pressure were analyzed for performance and interfaces of 3D printed coupons [15]. It was observed that the fiber content of the printed specimens is a function of the process parameters that exhibited flexural strength of 335 MPa and modulus of 30 GPa for the fiber content of 27% [15]. While the study found that the 3D printed continuous fiber composites is dependept on the fiber content, the multifunctional flexural-electrical properties and their coupling effects on the 3D printed continuous carbon fiber solid laminate composites were not included in [15]. The continuous carbon fiber-reinforced polylactic acid composite was manufactured using 3D printing to evaluate coupons' flexural strengths [16]. The comparative analysis of 3D printed coupons with or without preprocessed carbon fiber bundle was performed for measuring the improvement of the proposed method [16]. The mechanical strength was measured [16]. While the test results exhibited higher tensile strength and flexural strengths compared to the original carbon fiber reinforced test coupons, this paper did not address the coupling effects of the multifunctional properties in flexural-electrical mode of the 3D printed continuous carbon fiber solid laminate composites [16]. Flexural properties of the test coupons fabricated using material extrusion AM of endless carbon fiber-reinforced composites were investigated to assess the influence of layer height and width on mechanical properties [17]. The composites with two different 3k carbon fibers as reinforcements are 3D printed by material extrusion technique with various layer heights and layer widths [17]. Experimental results exhibited that the composites generated higher flexural strength at smaller layer height and the flexural modulus was dependent on the fiber volume content of the 3D printed composites [17]. The structural properties were decreased by the formation of delamination and voids that required further optimization [17]. The coupled flexural-electrical evaluation of the additively manufactured multifunctional continous carbon fiber solid laminate composites at ambient temperature was not addressed [17].
