    摘要： A method for forming a composite structure, using a mandrel that is later removed from the composite structure, involves production of a mandrel by depositing a particulate mixture, including an aggregate and a binder, into a mold and removing the mandrel from the mold. The mandrel may be treated while still in the mold by heating, curing with an agent, microwave energy, or by some combination thereof. Once finished, the mandrel can be used in manufacturing polymer and/or composite components. The mandrel can also include materials that can be easily removed from the finished composite structure by water, shakeout, chemically dissolving, or by some combination thereof. The mandrel can be a self-expanding mandrel, and can be used in a process or system for the manufacture of composite structures.

    摘要翻译： 使用稍后从复合结构中去除的心轴形成复合结构的方法涉及通过将包括骨料和粘合剂的颗粒混合物沉积到模具中并从模具中移除心轴来生产心轴。 可以通过加热，用试剂固化，微波能量或通过其一些组合，仍然在模具中处理心轴。 一旦完成，心轴可用于制造聚合物和/或复合组分。 心轴还可以包括能够通过水，摇摆，化学溶解或通过其组合容易地从成品复合结构中去除的材料。 心轴可以是自膨胀心轴，并且可以用于制造复合结构的过程或系统中。
