This paper presents a study on the application of fibers of turmeric residue (Curcuma longa) to solve the pollution problem of by-products after starch refining and improve the economic value of turmeric. The investigation uses turmeric by-products into fabricating composite based on epoxy resin to apply in the construction field, interior decoration as well as turning this by-product into a source of renewable materials. Turmeric pulp fibers are treated by NaOH solution to remove lignin, while maleic anhydride (MA) is used as a compatibility agent between the two phases of the material, helping to improve the properties of the composite. The physicochemical properties of the composite materials were determined by analytical methods: Fourier transforms infrared spectroscopy (FT-IR), X-ray diffraction (XRD), canning electron microscopy (SEM), and Thermogravimetric analysis (TGA). Composite material samples were further analyzed for physical and mechanical properties such as impact strength, flexural strength, and tensile strength. The results obtained the tensile strength and flexural strength of composite materials from turmeric baits reached values of 30,29 MPa and 133,11 MPa, respectively, higher than the tensile strength and flexural strength of epoxy. With a high content (60%) of turmeric residue, epoxy resin / natural turmeric fiber composite material is a new product with potential for practical applications and contributes to environmental protection.
