For decades, the utilization of hybrid composites incorporating natural fibers has been a prominent subject due to their exceptional advantages. Conversely, natural fibers possess high strength, affordability, ease of handling, eco-friendliness, and remarkable efficiency. In this research, banana, pineapple, and carbon fibers were employed with epoxy resin to produce single and hybrid composites. The objective was to examine the enhancement of strength, thermal degradation, and reduced flammability using fire retardant paint. The findings demonstrated a substantial improvement in tensile properties for the banana and pineapple hybrid composites, with increases of approximately 144% and 138%, respectively, compared to their non-hybrid counterparts. This percentage for flexural strength was 248% and 265%. Again, it was approximately 92% and 79% for impact strength. Incorporating carbon fibers with banana and pineapple fibers resulted in hybrid composites that showcased commendable fire-retardant properties and sustainability at high temperatures, as confirmed by thermogravimetric analysis. Moreover, the heat conduction rate through the composites after using fire paint was lowest in the banana fiber composite and highest in the pineapple hybrid composite. The outcomes of this research highlighted that adding carbon fiber significantly improves the composite's mechanical properties and ensure fire safety. [ABSTRACT FROM AUTHOR]
