Characterization of heat treated wood filled stryene maleic anhdride (SMA) composite

In this study, wood fıller SMA copolymer, engineering material, has been obtained through twin screw extruder adding the specific rate heat treated pine wood (10%, 20%, 30%, 40%, and 50%) to foamed SMA polymer. Deformation results have been achieved by analyzing of the mixing rate and the material characterization in heat treated wood-SMA composites prepared in specific rates. In comparasion of the experimental results, deformation results were compared with finite element method (FEM). According to density results, there is no significant diffence between the groups as a result of increasing wood filler rate. According to dimensional stability results, heat treated wood SMA composites have less dimensional changes than wood SMA composites. According to the accelerated weathering test results, colour changes developed when heat-treated filler rate is increased in this material. So, materials in 10% filler rate show minumum colour changes. According to the mechanical test results, TP group in 30% filler rate has the best results both in the flexural and the tensile strength. According to the TGA results, heat- treated wood SMA composites have more thermal stabile than wood SMA composites. According to the morpholojical results, it has been indicated a weak interaction between the heat-treated wood and SMA polymer among all groups. According to the reological analysis, the dynamic viscosity of composites has showed a significant increase at low frequencies. According to the deformation analysis result of FEM, it can be seen that the results obtained from the experimental solution are very close to the results obtained from the numerical solutions. As a result, it can be said that it is beneficial to use the FEM in the engineering design approach after the data obtained by the experimental solutions obtained meaningful values after application of the FEM.
