The CFRP waste was recycled through a controlled thermal process and the resulting weight loss behavior obtained via a muffle furnace was evaluated using a design of experiments and analysis of variance.

The inclusion of green fillers brings property enhancements that are normally seen with expensive nanofillers like carbon nanotubes or graphene: improvement of mechanical properties while keeping good thermal stability and antioxidant properties has been obtained. To compare the effect of the inclusion of the two different nanofillers at 15, 25 and 35 % wt loadings on the characteristics of polyethylene, physical, mechanical, and morphological tests were performed. Injection pellets were fabricated and used to fabricate coupons to evaluate the mechanical features by performing both flexural and tensile tests. Remarkable enhancements (up to 60 % with respect to the neat polymer) of certain mechanical properties were observed for composites with 35 % wt loading of nanofillers. Moreover, investigating the effect of the bio-based nanolignins inclusion at high loadings on both crystallization and melting temperature suggested the robust thermal stability of the presented composites.

However, the melt-state and solid-state properties of polymer nanocomposites are highly sensitive to the dispersion state of their constituents. This study investigates the effect of graphene nanoplatelets (GNPs) as secondary nanofillers in PE100/CB systems, with particular emphasis on melt sagging behavior governed by creeping flow. Two types of GNPs—few-layer graphene (FLG) and multi-layer graphene (MLG)—were incorporated to form hybrid nanocomposites with total filler contents of 2.25 wt.% (1.95 wt.% CB + 0.3 wt.% GNPs) and 2.55 wt.% (2.25 wt.% CB + 0.3 wt.% GNPs). Morphological observations using optical microscopy (OM) and field-emission scanning electron microscopy (FESEM) revealed that FLG, characterized by a higher structural defect density, achieved superior dispersion, whereas MLG showed a limited ability to disrupt CB agglomerates within the PE100 matrix. Rheological characterization, including small-amplitude oscillatory shear, shear-induced time-dependent measurements, and melt creep tests, demonstrated that FLG-containing hybrids exhibit enhanced melt viscosity and increased resistance to creep flow. Consequently, the addition of 0.3wt.% FLG caused a reduction in the sag index by up to 31.16% in compared with 2.25wt.% CB-filled systems. Tensile testing showed that FLG incorporation leads to slight improvements in break-point properties (e.g., a 14.6% increase in elongation at break for the 2.55 wt.% filled samples). This behavior is attributed to reduced stress concentration sites resulting from improved filler dispersion in the amorphous phase. These results demonstrate that CB/FLG hybridization provides an effective materials-based strategy for improving sagging resistance in PE100 while maintaining mechanical integrity</div></div>","PeriodicalId":34525,"journal":{"name":"Composites Part C Open Access","volume":"19 ","pages":"Article 100710"},"PeriodicalIF":7.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147395789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
