part was prepared with. Several basic principles applying to penetrant inspection are: 1. The penetrant must enter the defect in order to form an indication. It is important to allow sufficient time so the penetrant can fill the defect ... defect must be clean and free of contaminating materials so that the penetrant is free to enter. 2. If all penetrant is washed out of a defect, an indication cannot be formed. During the washing or rinsing operation, prior…

installed to restore the electrical bonding of the panel. [Figure 7-23] Ultraviolet (UV) light affects the strength of composite materials. Composite structures need to be protected by a top coating to prevent the effects of UV light. Special ... primers and paints have been developed to protect composite materials. Nondestructive Inspection (NDI) of Composites Visual Inspection A visual inspection is the primary inspection method for in-service inspections. Visible damage may include scorches, stains, dents, penetration, abrasions, or chips…

ohmmeter. Specific manufacturer’s instructions must be carefully followed. Thermography Thermography is an NDI technique often used with thin composite structures that use radiant electromagnetic thermal energy to detect flaws. Most common sources of heat are heat lamps or heater ... blankets. The basic principle of thermal inspection consists of measuring or mapping of surface temperatures when heat flows from, to, or through a test object. All thermographic techniques rely on differentials in thermal conductivity between normal, defect-free areas…
