| Abstract: | The morphology of bi axially self reinforced high density polyethylene samples, prepared from uni axially shearing injection molding, was investigated by transmission electron microscopy. The characteristic crystal microstructure of bi axially self reinforced high density polyethylene consisted of a low percentage of shish kababs and a high percentage of aligned lamellae. The lamellar outgrowths of shish kababs and the aligned lamellae interlocked laterally and thus formed the interlocking shish kababs. |

| Keywords: | interlocking shish kababs bi axial self reinforcement high density polyethylene |
