Abstract

Abstract A diving suit is fabricated to provide freedom of motion and protection from marine predators including a pair of neoprene sheets sandwiching a fist scale arrangement of overlapping plastic chips. Using a resilient adhesive to bond row after row of interconnected plastic chips onto the inner sheet of neoprene in the overlapping "fish scale like" arrangement provides a protective laminate. Covering the joined rows with the second neoprene sheet holds the suit together and reduces the possibility of snagging the chips'' exposed edges. Holes are made in the outer neoprene sheet and a liquid resilient adhesive is injected to coat the chips and fill any voids created between the two sheets. After a sufficient drying time, the laterally arranged rows of plastic chips are bent and flexed along axes perpendicular to the rows to break the small connecting portions between adjacent chips. Thusly resiliently bonded and segmented, the layered diver armor provides protection yet retains a high degree of flexibility to prevent diver fatigue.
