Summary: In this paper, the eco-friendly production of thermally conductive polyimide/boron nitride (PI/BN) composite sintered materials was reported. The synthesis of monomer salt (MS)/BN composite powders and PI/BN composite powders was achieved using a green solvent and solvent-free solid-state polymerization (SSP), respectively. The resulting PI/BN composite specimens showed significantly improved thermal conductivities compared to pure-PI specimens, with effective connections between BN nanosheets being attributed to the increased thermal conductivities. This study presents a novel and economical method for the preparation of highly thermally conductive PI composites.

Summary: In this study, an innovative use of vacuum filtration approach is proposed to modify the circumferential surface of structural carbon fiber, aiming to improve the interfacial adhesion of composites by constructing a synergistic hydrogen bond network. The obtained hybrid reinforcement exhibits significantly higher interfacial shear strength compared to untreated fiber and CNF/CNT grafted fiber. The improvement is mainly attributed to the formation of dense hydrogen bonds among CNFs, PVA, and CNTs, leading to larger energy consumption at interphase, as well as the spider's web-like structure of CNF/CNT that deflects cracks and promotes stress transfer.

Summary: In this study, short and short continuous fiber synergistic reinforced composites (S-CFRPCs) were successfully fabricated using fused filament fabrication. The effects of short fiber content on filament bonding properties were evaluated through short beam shear (SBS) and in-plane tensile shear tests. The results showed that specimens with 5% short fiber content exhibited higher load carrying capacities and significant fusion-bonding performances, with approximately 41% and 80% increase in interlaminar shear strength (ILSS) and in-plane shear strength, respectively, compared to specimens with 0% fiber content. The use of proper amounts of short fibers effectively improved the fusion-bonding properties of S-CFRPCs.

Summary: In this study, high-density grafting of carbon nanotube/carbon nanofiber (CNT/CNF) on carbon fiber surface was achieved, leading to improved interfacial shear strength. This reinforcement effect is mainly attributed to the improved wettability and the provision of sufficient hydrogen bonding and pinning effect. The appropriate amount of CNT/CNF hybrid also resulted in a gradual modulus transition at the interface, reducing stress concentration.
