Study on choice of guide sleeve material based on 3D hybrid woven forming of composites

The guide sleeve is the connection between layers during the 3D hybrid woven of large and complex component based on digital guiding master plate. Proper choice of guide sleeve materials is essential to the whole performance of composites, for both the guide sleeve and the fiber coiled on it for plane shaping are reinforcing materials. Thus not only the properties of guide sleeve should be deliberated, but also their interfacial bonding properties between resins and guide sleeve should be taken into consideration while choosing the material. After testing the interface tensile strength by universal testing machine, we use the scanning electron micro-scope (SEM) to analyze the joint surface morphology of composites before and after tensile test. And the result shows that carbon fiber-vinyl composite has excellent invasive between resins and high bonding strength. Meanwhile, because of its high specific strength, compared with aluminum alloy and stainless steel, carbon fiber-vinyl composite material is the perfect selection for guide sleeve.
