On the basis of the analysis of development oftransport technical systems the steady tendency
to application in their designs of composite materials is established. The prospects of use of additive technologies of the three-dimensional press for production of objects of irregular shape are
also noted. At the same time the method of selective local hardening by formation of topological
structures which configuration corresponds to fields of tension arising in use is analysed. A subject of researches was durability of samples fromcomposite material. The purpose of researches
was experimental justification of a possibility of increase in durability of objects of additive production from thermoplastic materials by their reinforcing by topological composite structures and the microwave oven of modifying. Researches on resistance to the stretching loadings of the threedimensional objects with the weakened sections created by means of additive FDM technology are executed. According to the accepted technique carried out definition of a configuration of fields of tension in composite material on computer solid-state model, made samples with the cavity received by modeling of a configuration by methodof the three-dimensional press filled a cavity with a composite with carbon fibers. A part of the received samples subjected to influence of the microwave oven of the electromagnetic field. Carried out tests on stretching. It is revealed that reinforcing of a sample from the thermoplastic material ABS the composite material containing carbon fibers significantly increases the size of explosive effort, at the same time the greatest effect (increase in explosive effort by 1,5 times) is reached at distribution of the reinforcing material according to the predicted fields of operational tension. Additional processing of the reinforced sample in the microwave oven the electromagnetic field with a frequency of 2450 MHz during 10 with leads to increase in explosive effort in comparison with control by 1,74 time, and the elasticity module – by 3,5 times. Results can be used at production of details of various technological and transport technical systems, in particular – aircraft to which durability and weight characteristics increased requirements are imposed.
