Abstract
Disclosed herein is a wood plastic composite panel made of a resin composite in which wood fiber having a size of 80 to 300 meshes is included in a synthetic resin matrix, the wood plastic composite panel being provided at the entire surface thereof with an embossed structure of a lumber cut-open pattern having an average depth of 200 to 900 μm and a linear micro concavo-convex structure having an average depth of 10 to 500 μm, the panel having a reflection rate of 10 to 50% when light is incident on the surface of the panel at an incidence angle of 60 degrees. The wood plastic composite panel according to the present invention has excellent strength and durability. Furthermore, the wood plastic composite panel according to the present invention exhibits excellent appearance and texture comparable with cut-open surfaces of natural lumbers although the panel has a surface structure different from the cut-open surfaces of the natural lumbers.
