Description

Technical Field

[0001] The present invention relates to the technical field of geogrids, and in particular to a system and method for intelligently manufacturing carbon fiber geogrids based on an MES platform. Background Art

[0002] Carbon fiber is a microcrystalline graphite material obtained by carbonizing and graphitizing organic fibers. It has the characteristics of high specific strength, high specific modulus, high temperature resistance, chemical corrosion resistance, radiation resistance, fatigue resistance, creep resistance, electrical conductivity, heat transfer and small thermal expansion coefficient. The geogrid woven from it has excellent properties such as acid resistance, alkali resistance, corrosion resistance, aging resistance, high tensile strength, low elongation at break, and good creep resistance.

[0003] With the continuous development of carbon fiber performance, more and more industries and products are beginning to use carbon fiber. However, in the geosynthetics industry, the use of carbon fiber is still in its infancy. China Patent Publication No. CN2753792Y authorized a "carbon fiber geogrid" on January 25, 2006. Its technical features are: it has a coating and a mesh cloth, the coating is applied to the periphery of the mesh cloth, and the mesh cloth is a mesh cloth woven from carbon fiber by a fine knitting machine. Since the mesh cloth is made of carbon fiber and woven by a fine knitting machine, it fully utilizes the high tensile strength of carbon fiber materials, so that the quality of the project is effectively guaranteed.

[0004] China Patent Publication No. CN 110552113 A disclosed a "method for manufacturing carbon fiber woven cloth" on December 10, 2019. Its technical features are: providing a method for manufacturing carbon fiber woven cloth, including carbon fiber merging and expansion, dipping, slitting and closing, weaving, shaping and packaging. Carbon fiber merging and expansion: using ultrasonic and electromagnetic super effects to widen multiple ingot carbon fibers and ensure that the carbon fiber bundles are evenly arranged within the specified range; the treated carbon fiber is rolled up, and the manufacturing method can manufacture wide-width carbon fiber woven cloth at high speed.
