This article presents the results of research and fabrication of energy-carrying composite materials from nitrocellulose (NC), cellulose (C) and unsaturated polyester. The results show that the material sample has satisfactory properties when the ratio nitrocellulose:cellulose (NC:C)-80:20 and the content of unsaturated polyester is 15%, the material has tensile strength is not less than 10 MPa (11.56 MPa), elongation is not less than 1.5% (4.2%), heat of combustion is not less than 500 kcal/g (513.6 kcal/g), flash temperature is not less than 180 oC (193 oC).
