摘要:
为了有效控制管道施工质量,提高施工效率,针对国内复合材料修复普遍采用的湿缠绕法存在的现场质量管控困难、效率低、易受污染、环境影响大等缺点,开发了一种光固化高强纤维复合材料预浸料,并对该预浸料的拉伸强度、拉伸模量、吸水性、剥离强度、微观形貌以及修复能力进行了试验研究。研究结果表明,光固化高强纤维复合材料预浸料各项性能优异,明显高于湿缠绕法的同等试样水平;光固化高强纤维复合材料预浸料的显微结构更加紧凑,树脂对纤维的浸润效果更好。此外,修复结构的水压试验表明,该纤维复合材料的修复作用是通过缺陷塑性变形实现应力传递的,且纤维复合材料修复结构的变形由内到外逐渐减弱。
Abstract:
In order to effectively control the construction quality, improve the efficiency of construction, overcome the on-site quality control difficulties, the inefficiency, the pollution and the environmental impact caused by the wet winding, the prepreg of the light-cured high strength glass fiber composites were developed. And the research has been done on the tensile strength, tensile modulus, water absorption, peel strength, microstructure and the repair ability. The results show that the properties of the prepreg of the light-cured high strength glass fiber composites are better than that of the wet winding. The microstructure of prepreg is more compact and the effect of the resin on fiber is better. In addition, the hydrostatic test of the repaired structure shows that the stress transfer of the fiber composite is realized through the plastic deformation of the defect, and the deformation of the fiber repaired structure decreases gradually from the inside to the outside.
