Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for fabricating large composite aircraft parts are time-consuming due to the need for extensive indexing and layup of fiber-reinforced materials, which occupies significant factory space and requires specialized machinery.
Innovation Solution
A method and system that subdivides the mandrel into zones, assigning different fabrication operations to each zone, allowing for simultaneous processing at multiple stations, including component, preform, and skin layer placement, without the need for specialized machinery, using a series of stations to efficiently lay up and harden composite parts.

1Productivity
If a single AFP machine traverses the entire part sequentially, then manufacturing precision is maintained, but productivity is reduced due to extensive indexing and layup time
Solution Approach 1:
The fabrication system divides the tool into multiple zones (e.g., first zone, second zone) and assigns different AFP machines to work on different zones simultaneously. This segmentation allows parallel processing of multiple part sections, eliminating the sequential traversal bottleneck and reducing overall fabrication time while maintaining quality standards.
Solution Approach 2:
The system transitions from a single-machine sequential approach to a multi-machine parallel approach by adding spatial dimensionality to the fabrication process. Multiple AFP machines operate concurrently on different zones of the tool, transforming the process from one-dimensional sequential work to multi-dimensional parallel operations.
2Productivity
If multiple AFP machines work on different zones simultaneously, then productivity increases, but device complexity increases
Solution Approach 1:
The system is divided into discrete zones with dedicated AFP machines for each zone, allowing independent operation and simplified control of individual units. Each machine handles a specific zone, reducing the complexity burden on any single machine while achieving high overall productivity through coordinated parallel operations.
