Problems solved by technology

However, if an out-of-tolerance condition within the composite part indicates a lower than desired quality level, the entire composite part may need to be reworked or discarded
For large composite parts such as aircraft wings, a single reworked or discarded composite part is a significant waste of resources, time and labor

Embodiment

[0321] Referring more specifically to the accompanying drawings, it may be found at, for example, Figure 20 aircraft manufacturing and servicing in method 2000 and Figure 21 Embodiments of the present disclosure are described in the context of the illustrated aircraft 2002 . During pre-production, method 2000 may include specification and design 2004 of aircraft 2002 and material procurement 2006 . During production, component and subassembly manufacturing 2008 and system integration 2010 of the aircraft 2002 are performed. Thereafter, the aircraft may be certified in 2002 and delivered in 2012 for entry into service in 2014. During customer use, aircraft 2002 is scheduled for maintenance and service 2016 to perform routine work (which may also include refurbishment, reconfiguration, refurbishment, etc.). Any one or more suitable phases of production and service that may be described in method 2000 (e.g., specification and design 2004, material procurement 2006, component a...

Abstract

The invention relates to a thermographic inspection for tape layup machines. Systems and methods are provided for thermal inspection of tape layup. One embodiment is a method for performing inspectionof a tape layup. The method comprises laying up tape onto a surface of a laminate, applying heat to tack the tape to the surface, and generating thermographic images of the tape as applied to the surface.

Description

technical field [0001] The present disclosure relates to the field of manufacturing, and in particular to tape layup machines that produce laminates comprising multiple layers of tape. Background technique [0002] Multilayer laminates of constituent materials, such as carbon fiber reinforced polymer (CFRP), can be formed into any of a variety of shapes for curing into composite parts. To facilitate the manufacture of composite parts, tape lay-up machines such as automatic fiber placement (AFP) machines or automatic tape lay-up (ATL) machines can be utilized. For example, a tape layup machine may lay up one or more layers of tows of constituent materials that form a laminate, which is then hardened (eg, cured or consolidated) to form a composite part. [0003] Operation of the tape layering machine may be directed by a numerically controlled (NC) program directing the motion of the tape layering machine. The tape layup machine can dispense multiple tows onto the laminate a...
