Recently, short-fiber-reinforced thermoplastic composites (SFRTPCs) have been playing a more and crucial role in the application of automotive interior materials due to their advantages low density environmental resistance properties. However, relevant mechanical properties need be optimized. Previous investigations revealed that surface modification fibers is useful improve In this work, carbon fiber (CF)-reinforced polylactic acid (PLA) modified with MXene graphene oxide (GO) were prepared by twin-screw extrusion injection molding methods. Short CF was firstly polyetherimide (PEI), then different weight ratios MXene-GO (1:1) subsequently on PEI-CF. Finally, flexural failure mechanisms analyzed. The results showed successfully coated surface, strength modulus CF-PEI-MXene-GO-reinforced PLA (CF-PEI-MG/PLA) composite improved compared CF/PLA composite. addition, fracture sections flat white, bonded well for CF-PEI-0.1MG/PLA present study could provide reference further improving performance PLA-related composites.

Abstract Despite Canada's abundant biomass resources, a significant portion remains underutilized due to lack of large‐scale industrial applications. This research explores the utilization low‐value biomass, specifically aspen fiber, in fused filament fabrication (FFF) develop biocomposites. Various chemical treatments (NaOH, silane, and maleic anhydride (MA)) were applied improve fiber compatibility with polylactic acid (PLA). Both untreated treated fibers at 10 wt% loadings blended PLA extruded into 3D printable filaments. Results showed that MA‐treated fiber‐based composites had around 15% higher tensile strength modulus along 30% enhancement storage than ones. Additionally, 25% reduction water uptake was witnessed aspen‐derived composites. Furthermore, effect loading on mechanical performance explored by producing aspen‐PLA weight percentages (10, 20, 30). successfully 3D‐printing biocomposites up 30 content without nozzle clogging, properties deteriorated loading. All findings highlight untapped potential development value‐added Highlights Underutilized Aspen combined Successfully 3D‐printed wood The optimal printing temperature for FFF found be 220°C NaOH, (MA) applied.
