Abstract

AbstractA novel manufacturing process for wood-polypropylene composite (WPC) panels reinforced with fiber-reinforced polymer (FRP) sheets was implemented using a double belt pressing technology. FRP sheets were placed on both sides of the WPC agglomerates during fabrication, which resulted in increased productivity and reduced thermal stresses compared with secondary bonding processes. Significant improvements in the mechanical properties of the FRP reinforced sheet panels were found during flexural and tensile tests on the coupon level. Even with addition of only one layer of FRP reinforcement on both sides of a WPC panel, the flexural modulus and strength increased by a factor of 2.6 and 3.8, respectively. Furthermore, the flexural and tensile properties of the WPC material considered in this study were found to be superior compared with the properties of an extruded WPC material. The changes in the flexural modulus of the FRP reinforced WPC panels with respect to the number of FRP layers were predicted...
