Improving the Efficiency of Eddy Current Control of Carbon Fiber Objects by Increasing the Sensitivity to the Orientation of Carbon Fibers

The work is devoted to increasing the efficiency of eddy current testing of carbon fiber objects. This is achieved by increasing the sensitivity of the eddy current probe (ECP) to changes in the direction of carbon fibers during scanning. The developed ECP is designed to detect delamination-type defects in multilayer carbon-fiber materials, as well as to record the deviation of the direction of carbon-fiber fibers from a given orientation.

Keywords: eddy current probe, angular orientation, multilayer carbon fiber material, delamination.

Modeling the optimal composition of a bonded diamond tool and technological modes of the processing process

The paper reveals the phenomenon of a diamond tool with an organic binder based on a foamed epoxy resin cured with polyethylene polyamine, which consists in a sharp decrease in the depth of the disturbed fractured layer and surface roughness when processing brittle non-metallic materials. A mathematical model has been developed that describes the thermal processes occurring in the contact zone diamond grain binder composite material being processed when processing various materials with a bonded diamond tool. Numerous experimental results have been obtained confirming the correctness of theoretical calculations.
