Introduction. Currently, a significant widespread composites with metal matrix (MCM), which include metals, reinforced continuous fibers. MKM have high performance properties, depending on the nature of the matrix, geometry and distribution of the filler. The main-matrych his material is aluminum and its alloys, hardening phase - carbon, boric or steel fibers. Formulation of the problem. One of the problems is the use of MCM fiber connecting them with each other and with designs made from conventional metals and alloys. Mechanical fastening with bolts and rivets weakens the structure as drilling associated with the destruction of the fibers. For pro-BAKING strength of solder joints must apply considerable overlap. Fusion welding leads to a significant weakening of reinforcing fibers because of their long stay in the area you-high temperatures. The purpose of the work. The aim is to analyze the characteristics of fiber welding MCM pressure first point and diffusion, and determine its scope. Statement of the material. An important feature of these processes is negligible thermal influence of the welding process into fibers microns. These methods are used for welding pieces of the connection MKM and connecting them with homogeneous materials. At the same time, structural steel and person-composite materials opportunities to impede selection modes welding and techno-logy complicate their connection. For composite material with boron fiber volume content of 20 to 30% of complications during the dot-Volyn NGO and seam welding does not occur, welding is almost indistinguishable from the known to aluminum alloys. As the increase of boron fibers nonconducting significantly hampered conditions of the molten core, which requires the use of special electrodes and forms rigid regimes re-welding. Highly durable diffusion connections MCM from aluminum with each other and with titanium alloys can be achieved optimal design choice connection and use of intermediate metal layers, as that may be used copper, nickel and some other ...
