| Abstract Scope |
Many continuous carbon fiber reinforced (CCFR) composite tubes are
manufactured using fiber tow filament winding of resin impregnated tows. While such manufacturing method allows some variation in fiber angle along the length of the tube, low axial angles (< 40°) are not often accessible because the wet tows tend to slide along the circumference of the tube during fabrication. This manufacturing constraint limits the ability to achieve longitudinal placed tows and high axial stiffness. Other methods like resin infusion of cylindrical woven dry-fiber preforms are
available in limited tow angles and cannot readily vary fiber angles. Currently, the ability to easily vary tow angles along the length of the tube to optimize for specified loading conditions is limited to capital-intensive slow fabrication processes such as automated fiber placement (AFP) or labor-intensive hand lay-up. Here, we investigate a new method of composite tube manufacturing in which Continuous Fiber 3D (CF3D®) additively manufactured fiber tow preforms are printed and rolled onto a tube mandrel before cure. This method of manufacturing not only allows variation of fiber angles along the length of a composite tube but also enables fiber placement parallel to the axis of the tube (0°). Through this work, we optimize the fiber angles along the length and thickness of a composite tube for compression strength and compare the results with other variations of fiber architecture including published results of optimized filament wound composite tube. |
