Abstract: The composite materials made from elastomer and memory alloys, is claimed, where the composite material is manufactured from resilient elastomeric matrix (1) and elastomeric parts in desired design and shapes and from an alloy with the memory properties or memory-alloy and in the low-temperature form the elastomeric matrix and elastomeric parts are mechanically embedded with memory elements (2), which are suitable for manufacturing mobile industrial and art-design products that are used in various constructions as design components moving in different ways. The composite materials made from elastomer and memory alloys, is claimed, where the composite material is manufactured from resilient elastomeric matrix (1) and elastomeric parts in desired design and shapes and from an alloy with the memory properties or memory-alloy and in the low-temperature form the elastomeric matrix and elastomeric parts are mechanically embedded with memory elements (2), which are suitable for manufacturing mobile industrial and art-design products that are used in various constructions as design components moving in different ways. The mobility of the design components is guaranteed as their recurring shape changes with the temperature changes of the environment or its memory elements are determined by switching on and switching off the electric current present in the memory elements connected circuit through the opposite effect of the elastic force and the pseudo-elastic force of the elastomeric matrix parts embedded with memory elements. The memory elements are embedded in the elastomeric matrix by the martensitic deformation of the design shape of the elastomeric matrix-matched low-temperature form in the elastomeric matrix in a conventional injection molding process, where the elastomeric matrix is formed to its design form at a room temperature and is effected by its elasticity during the cooling of the memory elements at the starting temperature of martensitic deformation thus forming the memory elements embedded with a new composite material with new mechanical properties. The elastomeric parts embedded with the memory elements are polymerized to their design form by a self-or-cold curing method or a vulcanization method at temperatures lower than the starting temperature of martensitic reverse transformation of the memory elements. The elastomeric parts are shaped to its design form at room temperature in a conventional injection molding method and are polymerized to its design, where the elastomeric parts are affected by its elasticity during the cooling of the memory element at the starting temperature of martensitic deformation. The memory element is mechanically molded in its design form by martensitic deformation of the elastomeric-adjusted low-temperature form with the elastomeric parts that are formed to a unified design-form thus forming a new composite material with new mechanical properties. The design components made from these elastomeric matrix and parts are attached in different lighting or heating systems and thermal equipments, where the reversible movements of the elastomeric matrix and parts are generated while directly heating the system after switching on the system. The elastic force of the elastomeric matrix or the elastomeric parts and the excess pseudo elastic force of the memory elements are generated by cooling after switching off the system, where the decline of pseudo-elastic force of the memory elements takes place in excess than the elastic force of the elastomeric matrix and the elastomeric parts. The memory elements are connected to a power source by the electrical contacts present on their endings and are heated by the electric current. An independent claim is included for car tires made of a composite material.
