Abstract The growing demand for lightweight and sustainable materials has driven research into hybrid composites that combine synthetic natural fibers. This study aims to investigate the tensile flexural behavior of carbon fiber (CF) glass (GF) composites, alongside incorporating flax hemp were fabricated using vacuum bagging technique, ensuring uniform distribution optimized mechanical properties. Experimental results revealed CF exhibited highest ultimate strength (~550 MPa), with failure dominated by matrix cracking breakage due their inherent brittleness. GF while having a lower (~450 demonstrated greater ductility, attributed pull‐out cracking. Hybrid (H1), combining GF, showed intermediate (~500 reflecting mixed modes. In contrast, (FH H2) displayed significantly strengths (~150–200 MPa) weaker fiber‐matrix interactions moisture sensitivity. Despite strength, provided balance between performance sustainability, making them promising alternative structural applications in automotive, aerospace, eco‐friendly engineering. These findings highlight potential reducing environmental impact maintaining integrity, offering viable solution next‐generation materials. Highlights CF, H1, FH, H2 prepared through bagging. brittle failure; was ductile moderate. H1 hybrids combined balanced at ~500 MPa. Natural prioritize sustainability strength. offer mix eco‐friendliness improved durability.
