Experimental Research of bearing ability of a compound heavily composite parts


The article analyzes the results of studies to substantiate the principles of construction of connections of details from composite materials (CM), on the basis of which the proposed new design and technological solutions (CTE) of the metal-composite joints. To implement an effective transition from the part of the Cabinet to the metal Butt fittings developed new ways to connect with KM molded into longitudinal and transverse mounting trace elements formed or mounted on the metal parts. The results of an experimental study of the carrying capacity of the new CTE composite metal-based compounds molded into longitudinal and transversal CM mounting micronutrients. A system for providing an integrated experimental strength analysis and design, which includes methods of conducting experiments, design samples and test devices. The results of experiments to determine the force pulling the fastening micronutrients longitudinal connection, depending on the design and technological factors on the basis of which are designed and tested samples of the compounds of carbon fiber cross-sectional area 34 and 400mm2. For compounds of trace elements with mounting cross-link the results of the experimental determination of the coefficients of compliance; the degree of reduction of carbon plastics strength of different structures in the area of ​​implementation of the cylindrical pin diameter of 0.8, 1.0, 1.5 and 2.0mm and pyramidal (milled); anisotropy strength carbon fiber, glass and organoplastic to collapse depending on the structure of the CM, the loading direction, the sizes of fasteners and method for installing (introducing a prepreg and molding or co-drilled holes after polymerization km). The designs of the samples of various compounds and the results of the experimental determination of static strength. Experimental data were analyzed to study the carrying capacity of the modified polupetlevogo compound and its elements. The major finding of the work is that the methods proposed compounds have a high coefficient of performance (0.7 … 1.0) in the absence of any amplification in a formation zone for unidirectional interface km and adapted for integration into the structure of the unit during its manufacture.
