发明名称 Composite core and method of making same
摘要 <p>A method of wrapping a plurality of mandrels (1201, 1503, 1603, 1405, 1701, 1901, 2505) with a composite material (1401, 1501, 2603, 1103, 1601) can include rotating each mandrel (1201, 1503, 1603, 1405, 1701, 1901, 2505) at a rotational speed; translating each mandrel (1201, 1503, 1603, 1405, 1701, 1901, 2505) at a translation speed; positioning each mandrel (1201, 1503, 1603, 1405, 1701, 1901, 2505) back to back such that an aft face of a preceding mandrel (1201, 1503, 1603, 1405, 1701, 1901, 2505) is approximate to a forward face of a trailing mandrel (1201, 1503, 1603, 1405, 1701, 1901, 2505); and sequentially wrapping each mandrel (1201, 1503, 1603, 1405, 1701, 1901, 2505) with the composite material (1401, 1501, 2603, 1103, 1601) in a helical orientation.</p>
