초록

A molded structural panel with substantially parallel major surfaces includes integrally formed thin thermosetting resin high density outer sections. Less dense thermosetting resin foam intermediate sections extend inwardly from the outer sections with the density of the intermediate sections decreasing substantially uniformly with increased spacing from the outer sections. A thin thermosetting resin high density central section is located between the intermediate sections. The high density outer sections are in a stressed state from the pressure of the ...
