ABSTRACT:
A material for use as a core in panels or structural members includes a longitudinal and transverse axis which lie in a common plane. The material includes alternating first and second strips that are interconnected at spaced intervals along the longitudinal axis by lands lying in the common plane. Each of the first strips is formed to have portions lying to one side of the common plane and each of the second strips has portions lying to the other side of the common plane. The interconnected lands define webs extending along the transverse axis to provide inherent stiffness to the material.
