For different frequencies and probe layouts, using the C display, you can detect 1/16 inch-3/4 between the carbon fiber panel and the foam core material Debonding defects with inch diameter; it can detect the debonding between the aluminum panel and the foam core material and the adhesion between the foam.
Different types of core material foam plastic have different uses. The core material of the second stage test piece is two cashem 50mm thick ROHACELL® 51WF The foam is glued together.Core material foam plastic> Air-coupled ultrasonic testing of core material foam plastic board: The first stage of the test, the test pieces for defects include the debonding of different diameters between carbon fiber panels, aluminum panels and core materials, and those without panels In this case, the debonding between two pieces of foam bonded together.
Core material foam, core material foam manufacturer, core material foam price How to correctly use the core material foam plastic box for heat preservation. Because of the inhomogeneity of the core foam plastic material, the existence of the interface between the foam cell wall and the pores causes the foam material itself to contain an interface with a sharp change in acoustic impedance, which leads to a large scattering attenuation The ultrasonic testing tests at the frequencies of 225kHz and 400kHz failed, and the signals were all attenuated
