Tensile Mechanical Properties of Three-Strand PE/SiO₂Composite Fiber Rope

Abstract

The tensile mechanical properties of polyethylene/silica (PE/SiO2) composite fiber and three-strand PE/SiO2composite fiber ropes were investigated. It was found that the SiO2content had a significant effect on the tensile mechanical properties of composite fiber. The breaking force of the fishing three-strand PE/SiO2composite fiber rope with diameter 8 mm was 15.8 kN. Compared to common synthetic fiber rope with the same diameter, fishing three-strand PE/SiO2composite fiber rope had higher breaking force and less elongation. On the premise of maintain the breaking force, the common synthetic fiber rope could be replaced by the fishing three-strand PE/SiO2composite fiber rope in fishing area, and the linear density, the elongation at break, the netting gear resistance and using diameter of rope decreased. Therefore, an efficient method to improve the tensile mechanical properties and lower cost by using composite fiber rope was established.

The study of 3-strand PP/PE composite monofilament Rope

“…The breaking strength, knot breaking strength and percentage of breaking elongation of the fishing PP/PE composite monofilament are respectively 65.4cN/tex, 63.3cN/tex and 12.5%, in which, the breaking strength and knot breaking strength are improved by 25.8% and 75.8% than the fishing PE monofilament. The internal molecular orientation and structure of fishing PP/PE composite monofilament are modified by the modification, the molecular chain is gradually arranged more closely along the drawing direction with the enhanced orientation, and thus the crystallinity, orientation, breaking strength and knot breaking strength of the fishing PP/PE composite monofilament are increased [1][2][3][4][5][6][7][8] . Table 2 shows the comparison of tensile mechanical properties between the fishing PP/PE composite monofilament and common synthesized fibers.…”

“…PP rope and PE rope are widely used in trawl fisheries, deep water cage farming and barrier net farming, they are made of common PE monofilament and common PP monofilament in a single rope process, and their tensile mechanical properties need to be improved; as the basic structural element of a rope, the common PE monofilament and common PP monofilament are respectively made of high density PE (HDPE) and PP in the traditional spinning process [1][2][3][4][5][6][7][8] . The rope performance directly determines the expansion, complication, offshore work specialization and anti-wave safety of marine fisheries and projects(e.g.…”

“…trawl, deep water cage, large floating rope barrier net, and barrier net dam for ecological marine farming, etc) [9][10][11][12] . The progress of modern fishery brings a higher demand for the performance-price ratio, safety and tensile mechanical properties of the rope, and it urgently needs to carry out the research, development and industrialized application of new rope materials [7][8][9][10][11][12][13][14][15][16][17][18] . The ultra high molecular weight polyethylene fiber rope has outstanding properties but is expensive at present, and there are only a few researches on its application and demonstration in fisheries of China, so it can not be widely generalized [5,[9][10][11][12][13][14][15][16][17][18][19][20] .…”
