While Y or Al containing compounds are extensively utilized as additives in the hot-press sintering of monolithic h-BN ceramics to enhance density and strength, their application in the production of continuous h-BN fibers remains under-explored. In this study, polymer-derived h-BN fibers doped with Y and Al elements were prepared and systematically investigated. The effects of these additives on the crystallization and properties of the derived ceramic fiber were analyzed. The results demonstrate that Y, Al, and Y/Al doping promote the growth of h-BN grains. Additionally, the formation of borate and yttrium aluminate in the Y and Al co-doped fibers, which melt at high temperatures, creates a liquid phase that aids in the bonding of BN layers. This liquid phase promotes the closure of micropores and densifies the structure. Conversely, it was observed that the introduction of Y/Al hindered the formation of excessively large h-BN grains, with an Lc of only 11 nm and a La of 27 nm when treated at 2000 °C. Furthermore, the tensile strength of the Y/Al-doped fibers was found to peak at 860 MPa upon treatment at 2000 °C, while Young’s modulus reached its maximum value of 110 GPa at the comparatively lower temperature of 1800 °C.

This approach aims to enhance the mechanical performance of 3DP components while eliminating the need for rigid molds. The MLC was fabricated by producing a flat PA12 3DP core via powder bed fusion, applying unidirectional glass fibers using tailored fiber placement (TFP), and encasing it in a braided biaxial carbon fiber sleeve. Flexural and tensile tests were performed. Micro-computed tomography (micro-CT) was used to analyze the internal structure. The mechanical behavior of the textile-reinforced composite layer was modeled using the Chamis model and classical laminate theory (CLT), with predictions compared to experimental results. The MLC exhibited a tensile strength of approximately 300 MPa, a modulus of 20 GPa, and a low average density of 1.4 g/cm3, resulting in a specific modulus comparable to that of aluminum alloys, thereby confirming its suitability for Lightweight structural applications. Both the Chamis and CLT models showed good agreement with experimental data, demonstrating their effectiveness in predicting and optimizing reinforcement structures. This study highlights the potential of utilizing 3D-printed cores as structural frames for fiber reinforcement. When combined with non-rigid molds, such as those used in infusion techniques, this novel approach eliminates the need for expensive production tools, significantly improving the cost-effectiveness of composite manufacturing.
