Abstract: A method of wrapping a plurality of mandrels with a composite material can include rotating each mandrel at a rotational speed; translating each mandrel at a translation speed; positioning each mandrel back to back such that an aft face of a preceding mandrel is approximate to a forward face of a trailing mandrel; and sequentially wrapping each mandrel with the composite material in a helical orientation.
Abstract translation: 用复合材料包裹多个心轴的方法可以包括以一转动速度旋转每个心轴; 以平移速度平移每个心轴; 将每个心轴背靠背定位，使得前一个心轴的后表面接近拖尾心轴的前面; 并且顺序地将每个心轴与复合材料缠绕成螺旋方向。
