Problems solved by technology

[0003] Inspecting composite parts for defects is complicated by the fact that the interior of the composite part is not exposed for viewing
Therefore, the internal composition of composite parts cannot be determined with the naked eye
This means that it is not possible to visually inspect composite parts in order to detect delamination between layers of composite parts

Abstract

X-ray sidescatter inspection of laminates. Systems and methods are provided for detecting gaps in composite parts. One method includes radiating a beam of x-rays in a firing direction towards surfaceof a multilayer Carbon Fiber Reinforced Polymer (CFRP) part, acquiring data indicating intensity of sidescatter radiation received at an x-ray detector that extends along the CFRP part in the firing direction, and examining the acquired data for gaps at the CFRP part based on differences in intensity indicated by the data.

Description

technical field [0001] The present disclosure relates to the field of composite materials, and in particular, to the inspection of composite materials. Background technique [0002] Composite parts, such as those made from carbon fiber reinforced polymer (CFRP), are made from multiple layers of composite material that are cured together to form a monolithic integrated part. After curing has completed, the part can be secured to other composite parts to form larger structures. For example, composite skins of an aircraft may be fixed to support the structure of the aircraft so as to form part of the fuselage of the aircraft. [0003] Inspection of composite parts for defects is complicated by the fact that the interior of the composite part is not exposed for viewing. Therefore, the internal composition of composite parts cannot be determined visually. This means that it is not possible to visually inspect the composite part in order to detect delamination between the layer...
