Abstract
A skin layer is formed on sides of a resin panel along the direction of the panel thickness and both surfaces of the resin panel substantially orthogonal to the sides. An expanded layer is formed in an inner part of the panel surrounded by the skin layer to have a multiplicity of voids. Inner ribs are formed of solid layers in the expanded layer to extend along the surfaces and the direction of the panel thickness so that both the longitudinal ends of each inner rib continue out to the skin layer at the opposed sides. Reinforcing members are inserted into the inner ribs respectively, to expose both the longitudinal end surfaces thereof from the opposed sides. Both the longitudinal end surfaces of each reinforcing member are formed with engaging holes releasably engageable with a support member for supporting the reinforcing member in the cavity of the mold assembly.
