Rigidity-variable composite material, rigidity-variable system and grabbing equipment

The invention provides a rigidity-variable composite material. The rigidity-variable composite material comprises a base material made of a first material; and inclusions made of a second material; wherein the inclusion flows through the substrate, and in the state that the substrate is pressed, the inclusion is suitable for reacting with the substrate so as to change the rigidity of at least one part of the pressed position of the substrate. In the state that the base material is pressed, the base material made of the first material reacts with the inclusions made of the second material, so that the rigidity of at least one part of the pressed position of the base material is improved, the abrasion resistance of the position can be improved, and the service life of the position making contact with an object can be effectively prolonged. The invention further provides a rigidity variable system and grabbing equipment. 本公开提供一种刚度可变复合材料，包括：第一材料制成的基材；以及第二材料制成的夹杂物；其中，夹杂物流经基材，在基材受到压力的状态下，夹杂物适用于与基材反应，用以改变基材的至少一部分受压位
