摘要
Abstract
The large-size solid rocket composite case usually adopts the winding technology of carbon fiber/epoxy resin.During the winding process,the friction with the yarn roller significantly damages the fiber,resulting in the low strength of the carbon fiber composite case,and the damage mechanism of the carbon fiber fuzzing and broken is unknown.In this paper,the effects of winding tension and winding rate on the frictional damage of carbon fiber bundles and the properties of the composites were studied by means of filament winding equipment.The degree of wear was evaluated by comparing the tensile strength of carbon fiber bundles,tensile strength of NOL ring composite,the amount of fiber and the morphology of serosa before and after wear,and the relationship between mechanical properties and wear degree was established.With the increase of winding tension,the wear degree of carbon fiber bundle increases gradually,while the mechanical properties of NOL ring increase firstly and then decrease.When the winding speed increases gradually,the wear degree of carbon also increases,and the breaking strength decreases slowly at first,and then decreases rapidly when the winding speed is greater than a certain threshold,which is basically consistent with the trend of tensile strength of NOL ring.The key parameters and conclusions of filament winding process can be used for reference to enhance the fiber strength performance of large-size T800 carbon composite case.关键词
