Abstract: Composite materialization is an important trend in the structural upgrading of aerospace, defense, transportation, etc. Due to excellent mechanical properties and electrical conductivity, carbon fiber reinforced composites can be used in structural components whilst having the capacity to store/output electrical energy, which realize an integration of load bearing and electrical power charge/discharge. Hence, both the multifunctional material and the lightweight structure can be achieved using such carbon fibre composites. Structural power composites are comprised of carbon fiber electrodes, glass fiber separator and solid electrolytes, which are multifunctional polymer matrix transferreing load from reinforcments and enabling ions to travel between electrodes. This paper reviewed the typical structural power composites, including structural batteries, structural dielectric capacitors and structural supercapacitors. Constituent materials, device working principles and multifunctional characteristics were summarized for three types of structural power composites. The problems and challenges facing structural power composites were eventually dicussed. Insights were given for the development trend of structural power composites.
