Continuous two-dimensional woven net pipe CGFRP hybrid rib and preparation method thereof
The invention provides a continuous two-dimensional woven net pipe CGFRP hybrid rib and a preparation method thereof, and relates to the technical field of composite materials. The hybrid rib is prepared by taking an epoxy resin matrix, carbon fibers and glass fibers as raw materials through the steps of dipping, dispersing and combining, pre-forming, bundling, net sleeve weaving, winding, high-temperature forming, post-curing, traction and the like. According to the technical scheme, the method has the advantages of being simple, low in energy consumption and low in cost, the cost of the pure carbon fiber composite material rib is reduced, the durability and mechanical property of the glass fiber are improved, and the problems that a traditional mixed rib is low in circumferential strength and leaks a core are solved. The continuous two-dimensional braided net pipe CGFRP hybrid rib prepared by the method has higher mechanical property and durability, can be prepared into specific hybrid ribs according to mechanical property requirements and durability requirements, and can be quickly and widely applied to various projects.
本发明提供了一种连续二维编制网管CGFRP混杂筋及其制备方法，涉及复合材料技术领域。该发明的混杂筋以环氧树脂基体、碳纤维和玻璃纤维作为原料，通过浸渍、分散与合并、预成型、集束、网套编织、缠绕、高温成型、后固化、牵引等步骤制得。本发明技术方案具有方法简单，能耗少，成本低的优点，降低纯碳纤维复合材料筋的成本，提高了玻璃纤维耐久性能和力学性能，解决了传统混杂筋环向强度低、漏芯的问题。通过本发明方法制备的连续二维编制网管CGFRP混杂筋具有更高的力学性能和耐久性能，可按力学性能需求和耐久性需求制备特定混杂筋，迅速广泛的应用于各类工程中。
