INFLUENCE OF THE IRRADIATION, BY A PULSED ELECTRON BEAM, OF THE SURFACE OF SILUMIN AK5M2 AS PART OF A METAL/CARBON-FIBER-REINFORCED-PLASTIC COMPOSITE ON MECHANICAL PROPERTIES

The authors have presented results of uniaxial-tension testing of specimens of the layered composite "silumin/carbonfi ber-reinforced-plastic" (AK5M2/CFRP). AK5M2-grade silumin of hypoeutectic composition with the irradiation of the specimen′s surface by a pulsed laser beam was taken as the basic material. To create layered composites, carbon unidirectional fabric "CARBONWRAP Tape 230" produced at the Joint Stock Company Nanotechnological Center of Composites (NCC) was glued to the silumin surface. The binary epoxy compound "CARBONWRAP Resin 530+" produced at NCC was used as the binder. The uniaxial tension test of the specimens was implemented on an INSTRON 3382 testing machine at an extension rate of 0.3 mm/min. The evolution of deformation fi elds on the specimen′s surface was obtained using a VIC-3D digital optical system based on the method of correlation of digital stereoscopic images. From the testing results, the diagrams of deformation under uniaxial tension of the AK5M2/CFRP were constructed. The electron-microscopic image of the silumin surface layer was obtained by the scanning-electron-microscopy methods. An analysis of the structure of its infl uence on the physicomechanical properties was performed. An analysis of the strained state of the specimens was made by the patterns of distributions of longitudinal and transverse deformations in space and time
