Abstract
An improved mandrel for use in filament winding. Two embodiments are described for a new filament winding mandrel concept. The first embodiment comprises a plurality of spaced apart slots machined at an angle along the ends of the central mandrel section for use with machines of at least three degrees of motion. A second embodiment comprises a series of two circumferential rows of axial fins protruding along the circumference of the central section of the mandrel for use with machines having only two degrees of motion. A second configuration of the second embodiment is an addition of a strip of slots that are simply placed around and secured to the circumference of the mandrel at locations where fiber turn around is desired. This provides for fiber securing in place with minimal rather than requiring machining the axial fins into the tool.
