Method and apparatus for fabricating unidirectional materials for helicopter parts |
摘要 |
A unidirectional material for helicopter parts is fabricated by winding a composite-material roving delivered from a feeding mechanism of a filament winding device around and between a plurality of pins provided on a mandrel rotating about the longitudinal axis thereof, the roving feeding mechanism being moved in a traversing manner such that the feeding path of the roving becomes a figure eight figure, whereby the roving is thus wound to form a tubular mesh of obliquely crossing and staggered helixes of the roving around the mandrel. The material has an improved strength in a transverse direction of the mandrel.
