Abstract

A system and method for nondestructive inspection of unitized composite structures is provided. The system includes an infrared thermographic camera and a carriage that can be mounted on, for example,adjacent frames of the unitized composite structure. The carriage can move along the length of the frames while the infrared thermographic camera collects and analyzes thermographic images of the frame, skin, and stiffeners. The carriage can be moved to other frames and the inspection continued until the entire unitized composite structure has be inspected.

Description

technical field [0001] The present disclosure generally relates to methods and systems for non-destructive inspection of composite structures. Background technique [0002] Composite structures can be fabricated as a single modular composite structure, or as multiple components that must then be assembled. The manufacture of modular composite structures such as integrally reinforced skin panels offers several advantages. For example, shorter cycle times and less labor requirements reduce manufacturing costs. Additionally, fabricating a modular composite structure avoids the cost and time associated with using multiple different fasteners. [0003] However, combinatorial composite structures can present inspection challenges. Composite structures are often required to be inspected by non-destructive ultrasonic methods. Ultrasonic transducers may have access to all surfaces of multiple composite components prior to assembly. In the case of a modular composite structure, i...
