Abstract Due to the decline in petroleum‐derived resources and growing environmental awareness, scientists are seeking bio‐based alternatives for synthetic fibers resins composites. This study examines effect of partially substituting epoxy components with castor oil‐based bio‐resins. The goal is develop environmentally sustainable materials while maintaining performance. Epoxy methyl ricinoleate (EMR) was synthesized assessed as a supplementary component an copolymer cured Triethylenetetramine. Flax fabric used reinforcement epoxy–EMR matrices create eco‐friendly bio‐composites. matrix modified 10%, 20%, 30% EMR combined bidirectional flax balance toughness stiffness. Tensile strength increased by 6.5% EPEMR/20‐C. Impact improved 19% EPEMR/30‐C compared neat composite. incorporation, especially up enhanced ILSS about 13%. Fatigue performance 43% due better interfacial bonding. Low‐velocity impact tests were performed at 10 20 J perforation non‐perforation scenarios. composite 20% showed highest resistance. highlights its potential structural reduced weight EMR‐modified bio‐composites exhibited mechanical properties. These findings suggest their suitability automotive applications. Highlights effects bio‐resin on composites analyzed. High bio‐content composites, comprising approximately 50 wt%, developed. bio‐composites' fatigue via tougher Optimal addition enhances laminates' resistance LVI tests. Toughness adding EMR.
