Preparation and performance of continuous carbon fiber reinforced polyamide 6 composite tensile rod
摘要
Abstract
Continuous carbon-fiber-reinforced polyamide 6 prepreg was used to prepare a composite pull rod through a winding-molding process.The tensile properties of the composite pull rod were evaluated by using a self-made tensile tool,and its failure mode and failure mechanism were studied.The results indicated that increasing the molding pressure could reduce the pores in the composite as well as the internal defects,make the structure more compact,and improve the tensile strength of the pull rod.The composite pull rod without a collar showed a tensile failure position at its end,and the outer fiber was pulled and split.Only the inner fiber worked until it was pulled and broken.In this case,the ten-sile strength was low.The composite pull rod with a collar showed a tensile failure position close to the shaft sleeve on the side.The fiber was broken,and the fracture section was relatively flush.During the whole tensile process,the trans-verse restraint of the collar enabled all fibers to play a good tensile role,resulting in higher tensile strength.关键词
