| Abstract: | In this paper, the tensile mechanic performance of Ultra-high Molecular Weight Polyethylene(UHMWPE)netting twines and High Density Polyethylene(HDPE)netting twines was compared in standard laboratory. The results show that UHMWPE netting twines are higher than HDPE netting twines in tenacity, tensile modulus and ratio of loss of overhand knot breaking strength, while in percentage of breaking elongation the latter is bigger than the former. The conclusion reached can be used as reference in designing fishing gear and selecting netting materials. |
