The invention provides a truss type foldable space capsule based on a shape memory polymer composite material. The truss type foldable space capsule comprises a plurality of capsule body supporting beams and a plurality of end socket supporting beams. The two ends of each capsule body supporting beam are supported by annular supporting beams to form a cylindrical frame structure. The two ends of the end socket supporting beams are supported through the annular supporting beams and the annular butt joints to form a circular truncated cone frame structure. The circular truncated cone frame structure extends towards the outer side of the cylinder frame structure in the axial direction of the cylinder frame structure. The capsule body supporting beam, the end socket supporting beam, the annular supporting beam and the annular butt joint are all made of shape memory polymer composite materials. The space capsule is made of the shape memory polymer composite material, the weight of the spacecapsule is greatly reduced, and due to the fact that the shape memory polymer composite material has the folding characteristic, the occupied space of the space capsule is small.
本发明提供一种基于形状记忆聚合物复合材料的桁架式可收展太空舱,其包括多根舱体支撑梁、多根封头支撑梁;多根所述舱体支撑梁的两端通过环向支撑梁支撑形成圆筒框架结构;多根所述封头支撑梁的两端通过所述环向支撑梁和环向对接头支撑形成圆台框架结构;所述圆台框架结构沿所述圆筒框架结构的轴向向所述圆筒框架结构的外侧延伸;所述舱体支撑梁、所述封头支撑梁、所述环向支撑梁、所述环向对接头均由形状记忆聚合物复合材料制成。本发明的太空舱采用形状记忆聚合物复合材料制成,其重量大大减轻,且因形状记忆聚合物复合材料具有收拢特性,使其占用空间小。
