概要 | The biocomposites composed of sorbitol polyglycidyl ether (SPE), tung oil-pyrogallol resin (TPG) and wood flour (WF) were prepared by the compression molding at 190 degree C, and their thermal and mechanical properties were investigated in detail. The epoxy/hydroxy ratio was fixed to 1/1 in the curing reaction of SPE and TPG, based on the fact that the degree of addition of pyrogallol to each tung oil molecule for the TPG used as a flexible bio-based hardener is evaluated to be 2.3 by 1H NMR method. The SPE-TPG/WF biocomposites showed much higher storage moduli than SPE-TPG did, although tan delta peak temperatures of the biocomposites were a little lower than that of SPE-TPG. Tensile moduli of the biocomposites increased with an increase of WF content. Furthermore, the biocomposites had a little higher tensile strength than the cured neat resin did. FE-SEM analysis of the biocomposites revealed that WF is tightly incorporated into the crosslinked epoxy resins. |
