02Consider how surface treatments or additives could enhance the performance of natural materials for specific applications.

Method & Evidence

AimTo investigate the effect of chemical treatments on the fire resistance and thermal properties of hybrid jute-flax natural fiber reinforced epoxy composites.

MethodExperimental

ProcedureHybrid composites were fabricated using epoxy resin and woven jute and flax fibers. The natural fibers were pre-treated with a 5% alkaline solution. Jute fibers were further treated with a 20% ammonium sulfate solution, and flax fibers with a 10% diammonium phosphate solution to enhance fire resistance. Composites were produced via hand layup and cured using a hot press. Hardness, thickness, and mass were measured, followed by a fire experiment to assess flammability, heat distribution, and surface temperature.
