Composite materials are a type of material that is employed in the production of present and future aeronautical components.This study mainly takes into account High Silica Phenolic ablative material as well as designed ultra high strength steel material. One example is the Maraging steel shell, which is fused inside with an ablative Ethylene Propylene Diene Monomer (EPDM) rubber lining for heat protection. The current work creates and studies 2 kinds of artificial defects: a) 'Delamination' within levels of High Silica Phenolic composite liner while manufacturing and b) 'Debond' between Maraging steel casing and rubber liner interface. The aforesaid faults were non-destructively characterised utilizing various NDE techniques, including radiography testing, infrared thermography, and ultrasonic testing. A comparison investigation is carried out by comparing the outcomes of various approaches and procedures, and the key elements are noted. X-ray radiography is non-contact and non-invasive, revealing delamination/debonds as black lines in the radiographs. Thermography discloses faults as contrasting fluctuation owing to temperature differences, and ultrasonic testing is a connection which has revealed acoustic impedance incompatibilities.
