ABSTRACT:
A structural sandwich laminate formed of thin facings, such as aluminum or fiberglass sheets, bonded to a core panel. The core panel is formed of end-grain balsa wood having an array of holes punched therein, the holes having their centers on the apexes of a diamond, thereby making possible a high concentration of holes with an adequate separation therebetween to define a reticulated balsa core of high strength and exceptionally light weight.
