Wood flour thermoset composites using chemically modified epoxidized soybean oil

摘要: Thermosetting composites were prepared from chemically modified soybean oil and wood flour by compression molding technique. Resins epoxidized (ESO) softwood powder used as matrix reinforcing agent, respectively. ESO was initially methacrylic acid finally anhydride. For comparison, both neat resin blended with styrene in the composite preparation. The probable interaction among resin, established Fourier transform infrared spectroscopy, supported density functional theory calculations. Surface morphology of evaluated scanning electron microscope. flexural strength styrene-based co-monomer range 60.47–72.04 MPa, whereas that without between 25.68 37.62 MPa. tensile styrene-blended varied 22.15 35.87 MPa, 13.68–20.48 MPa for styrene-free composites. Styrene-blended showed an improvement mechanical, thermal, water resistance flame retardant properties over those having no styrene. higher amount anhydride overall
