The invention provides a bidirectional folding and unfolding light shield based on an intelligent composite material, a working method and a spacecraft, and relates to the technical field of spaceflight devices. According to the bidirectional unfolding and folding light shield based on the intelligent composite material, the characteristics of the intelligent composite material and the shape memory alloy are utilized, the light shield film, the unfolding driving piece and the folding driving piece are arranged, and the unfolding driving piece with the intelligent composite material and the folding driving piece with the shape memory alloy are matched; the two-way unfolding and folding process of the shading film can be achieved, impact on the shading film is small, a complex driving structure is not needed in the unfolding and folding process, unfolding and folding stability can be effectively improved, meanwhile, high rigidity of the intelligent composite material without external excitation is facilitated, and the supporting stability of the shading film can be effectively improved; therefore, the working stability of the bidirectional folding and unfolding light shield based on the intelligent composite material is effectively improved, the whole light shield is simple in structure and small in structural mass, and the carrying capacity of carrying work can be effectively improved.

    本发明提供了一种基于智能复合材料的双向展收遮光罩及工作方法和航天器,涉及航天装置技术领域。本发明的基于智能复合材料的双向展收遮光罩利用智能复合材料和形状记忆合金的特性,设置遮光膜、展开驱动件和收拢驱动件,通过具有智能复合材料的展开驱动件和具有形状记忆合金的收拢驱动件的配合,可实现遮光膜的双向展收过程,对遮光膜的冲击较小,且展收过程无需复杂驱动结构,可有效提升展收稳定性,同时利于智能复合材料在未受外界激励下的高刚度,可有效提升对遮光膜的支撑稳定性,进而有效提升基于智能复合材料的双向展收遮光罩的工作稳定性,且整个遮光罩的结构简单,结构质量较小,可有效提升运载工作的运载能力。
