In this study, the structural behavior of medium-density fiberboard (MDF) beams reinforced by unidirectional glass fiber-reinforced thermoset polyurethane outer layers is investigated by conducting beam bending and vibration tests followed by a parametric study. First, the MDF material properties are determined by 3-point bending and cantilever beam vibration tests. Then the same tests are conducted on the composite sandwich beam specimens produced by […]
