Ballistic-resistant panel including high modulus ultra high molecular weight polyethylene tape

A ballistic-resistant panel comprising:

• a plurality of interleaved layers consisting of non-fibrous ultra high molecular weight polyethylene tape;
• each of said layers of non-fibrous ultra high molecular weight polyethylene tape including a plurality of monolithic tape strips joined together in a sheet structure including joints between adjoining strips wherein said joints include an intermingling of molecules between said molecules of said adjoining strips and a higher strength in said joints than in said adjoining strips and each of said tape strips including a modulus of greater than 1400 grams per denier;
• said plurality of tape strips in each of said layers including a first portion of tape strips oriented at a first angle and a second portion of tape strips oriented at substantially 90 degrees with respect to said first angle;
• and
• said plurality of interleaved layers of non-fibrous ultra high molecular weight polyethylene tape bonded together by heat and pressure.
