Special mandrel and composite manufacturing technology (hot press forming technology, resin transfer molding technology, filament winding technology, etc.) is necessary to fabricate the composite structures with complex-curving surface.Traditionally, there are two kinds of mandrels to fabrication composite structures: multi-piece metal mandrel, water-soluble mandrel, however, the high cost, long cycle time, difficult extraction process of multi-piece metal mandrel and only once to use, long fabrication cycle, high labor-consuming to ideal with surface of water-soluble mandrel both hinder the development of composite manufacturing industry.Based on the drawback, a new kind of shape memory polymer (SMP) mandrel is designed and developed for composite industry.

为制备复杂截面的复合材料结构，需选用特定的模具，结合特定的复合材料成型工艺(热压罐成型工艺、树脂传递模塑成型工艺、纤维缠绕成型工艺，等)固化得到。传统的模具主要包括：多片金属模具和水溶性模具，然而，这两种模具都存在一些无法克服的缺点，比如：金属模具生产成本高，生产周期长，安装和脱模过程繁琐；水溶性模具为一次性模具，每次都需要重新塑模，重新打磨模具表面，花费时间长。为克服这些缺点，具有刚度可变特性的
