A METHOD OF MAKING A RIGID LIGHTWEIGHT LAMINATED PANEL COMPRISING FORMING A LAYUP OF A PLURALITY OF WOVEN FABRIC LAYERS IMOPREGNATED WITH A THERMOSETTING PLASTICS MATERIAL IN THE PLASTICIZED STATE, PUNCTURING THROUGH THE LAYUP IN ONE DIRECTION AT A PLURALITY OF SPACED POINTS SNAGGING THREADS OF THE WOVEN FABRIC LAYERS AND PULLING THEM THROUGH THE PUNCTURED REGIONS OF THE LAYUP IN THE OPPOSITE DIRECTION TO WHICH IT WAS PUNCTURED, SERVING THE SNAGGED THREADS WITHIN THE PUNCTURED REGIONS TO EXPOSE THEIR MATERIAL FIBERS, WHEREBY THE PLASTICIZED THERMOSETTING MATERIAL PENETRATES, INTO THE FIBERS OF THE SERVED THREADS AND FORMS THEREWITH SUBSTANTIALLY CONTINUOUS REINFORCING COLUMNS THROUGH THE LAYUP, AND THEN APPLYING THE HEAT AND PRESSURE TO THE LAYUP TO CAUSE HARDENING OF THE THERMOSETTING PLASTIC MATERIAL FOR COMPLETING THE PANEL.

Claim 3
Dependent Claim
85 words
A RIGID LIGHTWEIGHT STRUCTURAL PANEL COMPRISING A MULTIPLICITY OF LAYERS OF WOVEN FABRIC ARRANGED IN SUPERPOSED RELATION AND BONDED TOGETHER BY A HARDENABLE PLASTIC MATERIAL; AND A MULTIPLICITY OF SPACED SUBSTANTIALLY CONTINUOUS REINFORCING COLUMNS EXTENDING THROUGH SUBSTANTIALLY ALL OF SAID LAYERS AND MATERIALLY STRENGTHENING THE PANEL AGAINST DELAMINATION, THE COLUMNS CONSISTING OF A MULTITUDE OF SEVERAL FIBERS SNAGGED FROM THE WOVEN FABRIC LAYERS AND PULLED THROUGH THE PANEL IN ONE DIRECTION AND BEING SATURATED WITH THE HARDENABLE PLASTICS MATERIAL WITH WHICH THE LAYERS ARE IMPREGNATED.
