“…Epoxy resin (EP) has been widely used in various fields such as structural adhesives, coatings, functional composites, and machinery due to its excellent mechanical properties, admirable molding processability, good chemical resistance, superior thermal stability, and so on 1–3 . However, high friction coefficient, poor wear resistance, high brittleness, and wretched crack propagation resistance of the cured EP make it difficult to meet the critical engineering requirements and thus the extensive applications of EP are greatly restricted 4,5 .…”

Epoxy composites with simultaneously enhanced tribological and mechanical properties filled with basalt belt/reduced graphene oxide/paraffin wax (EP/BF/RGO/PW) have been successfully prepared. Experimental results indicated that the mechanical property of the composites was reinforced by basalt belt, and the tribological property was greatly improved by reduced graphene oxide/paraffin wax at the same time. Thanks to the synergy of PW and RGO sheets, the optimized coefficient of friction and wear rate of the composite declined by 77.5% and 14.4% than pure EP under dry friction conditions of 60 N and 0.42 m s−1. In comparison to pure EP, the tensile strength and modulus of the optimized composite increased by 75.5% and 100% on account of the robust basalt fibers. Thus, the combination of basalt fiber and reduced graphene oxide/paraffin wax can readily realize the introduction of enhancer and oil‐impregnation in EP, offering a promising approach for simultaneously improving the mechanical and tribological properties of epoxy.Highlights A novel BF/RGO/PW 3D skeleton was developed via a facile hydrothermal method. The BF/RGO/PW can enhance the mechanical and tribological properties of EP. The basalt fibers account for the improvement in mechanical property. A reduction of 77.5% in COF and a decrease of 14.4% in wear rate were realized.

Polylactic acid (PLA) is the prevailing raw material for fused deposition modeling (FDM) 3D printing filaments, offering benefits such as a low printing temperature, minimal shrinkage, and biodegradability. However, this material has challenges such as poor toughness, low heat deflection temperature, susceptibility to moisture‐induced thermal degradation, and high costs. This study addressed these concerns by incorporating natural bamboo fiber (BF) into PLA, elevating heat the deflection temperature and lowering the material costs. Additionally, a synthesized branched structure compatibilizer, in the form of epoxidized soybean oil‐branched cardanol ether (ESOn‐ECD), enhanced the toughness of PLA, the bonding strength between PLA and the BF surface, and the flowability of high‐fiber composites during processing and printing. The mechanical, thermal, and rheological properties were assessed, demonstrating the promising processing performance of PLA/BF/ESO3‐ECD. The fully biobased composite exhibits strength, toughness, good processability, excellent 3D printability, and durability, implying substantial potential in FDM 3D filament production.Highlights Bio‐based PLA/bamboo fiber/ESO3‐ECD FDM 3D printing filaments were developed. The excellent nucleation ability of the bamboo fibers enhances the crystallization rate and crystallinity of PLA. The epoxy values and branching degree of ESOn‐ECD are crucial for its effective modification.
