ABSTRACT

As a method for the mechanical strength increase in products made of composite and its uniformity increase in a product there is offered a structure modification in a SHF electromagnetic field of a standard frequency range. It is defined that a SHF modification contributes to the increase of bend stress by 11 – 16 %, cut stress increase by 13 – 21 %. During tests for an inter-laminar shear the samples processed withstand stress by 14 – 15 % more than reference samples. The study of the micro-structure in reference samples and processed ones with the use of the fractal analysis procedure has shown that a fractal dimensionality of micro-objects of the structure of material worked increased as compared with a reference sample by 14 – 22 %. This fact may be accepted as one of the mechanisms for material strength increase at the expense of the increase of contact interaction points of the matrix and reinforcing fibers.
