The article considers the stages of design, manufacture, assembling and testing a power truss structure of a liquid rocket engine made of polymer composite materials. It is  assumed that the power frame of carbon fiber will be similar to the metal, i.e. it will have the same location of the axes and mounting points of the engine components. Hence, the ways of overcoming a number of difficulties arising in the composite power frame design and manufacture are investigated. The advantages and disadvantages of using polymer composite materials when creating truss structures of propulsion systems are revealed. As a result of the metal power frame replacement in the truss structure for the carbon-fiber plastic one, it becomes possible to reduce the mass of such a structure by about  2 times, and the engine mass by about 20 kg
