Challenges in SOA Automated Fiber Placement for Composite Manufacturing

Automated Fiber Placement (AFP) is an intricate part of manufacturing advanced composite structures. Presently the key challenges in AFP for composite manufacturing are:

• AFP requires a great deal of experience, expertise, and labor to optimally plan the fiber placement paths, especially for large and thick structures. The number of decisions required is immense.
• Manual path planning by human experts is very time-consuming. Early planning decisions can have consequences later in the process.
• Expertise in AFP process planning requires years of trial-and-error experience on various structures and geometries. Such expert-level knowledge is needed to manufacture high-quality parts, especially for complex/contoured structures.
• Companies face "brain drain" issues due to an aging workforce, high turnover, and skill/labor shortages. Losing an expert AFP process planner can lead to increased development time, lower part quality, and compromised performance.
• Finding and acquiring such niche AFP talent is difficult. More advanced industry 4.0 and digitization concepts that could help are not yet widely adopted.
  

The high level of expertise required, time-consuming manual planning, risk of losing expert knowledge, and difficulty finding skilled AFP process planners pose significant challenges to composite manufacturing using AFP. New approaches are needed to capture and automate AFP process planning knowledge and decisions.

Expertise Shortages and Inefficiencies in Traditional Fiber Placement Methods

Several expertise shortages and inefficiencies persist in traditional fiber placement methods:

• Brain drain: As the experienced workforce ages and retires, companies face a loss of valuable expertise. High turnover rates and labor shortages exacerbate this issue, making it difficult to retain skilled process planners.
• Niche talent pool: AFP process planning requires a highly specialized skill set, which can only be acquired through years of hands-on experience. Finding and recruiting individuals with this expertise is challenging due to the relatively small talent pool.
• Time-consuming manual planning: Traditional fiber placement methods rely heavily on manual path planning by human experts. This process is labor-intensive and time-consuming, especially for large and complex structures.
• Consequences of early decisions: In manual planning, decisions made early in the process can have unforeseen consequences later on. This can lead to suboptimal fiber placement and reduced part quality.
• Limited adoption of advanced technologies: While industry 4.0 and digitization concepts offer potential solutions, their adoption within the AFP industry has been slow. This hinders the implementation of more efficient and automated process planning methods.

These challenges highlight the need for an artificially intelligent process planner that can capture and leverage expert knowledge, optimize fiber placement paths, and adapt to various structures and geometries, ultimately improving efficiency and part quality in AFP composite manufacturing.

Innovating with AI To Bring in a New Era in Fiber Placement Process Planning

The artificial intelligence (AI) can help usher in a new era of fiber placement process planning by addressing the challenges and inefficiencies of traditional methods:

• Capturing and retaining expertise: An AI process planner can incorporate domain knowledge and expert insights into a robust, permanent, and evolving system. This helps mitigate the impact of brain drain and ensures that valuable expertise is retained and utilized.
• Optimizing path planning: By leveraging machine learning algorithms and simulation capabilities, an AI process planner can analyze various fiber placement scenarios and generate optimized path plans. This reduces the reliance on time-consuming manual planning and improves overall efficiency.
• Adapting to complex structures: AI-driven process planning can handle complex geometries and contoured structures more effectively. The system can learn from historical data, design rules, and simulations to identify optimal fiber placement patterns for various part configurations.
• Continuous improvement: An AI process planner can continuously evolve and improve over time by incorporating new data, expert insights, and advanced simulation techniques. This adaptability ensures that the system remains up-to-date and efficient as manufacturing requirements change.
• Integration with industry 4.0: AI-based process planning aligns with the concepts of industry 4.0 and digitization. It enables the integration of advanced technologies, such as machine learning, simulation, and data analytics, into the fiber placement process, driving innovation and efficiency.

By leveraging AI the fiber placement industry can transition from relying on individual expertise to a more scalable, efficient, and adaptable process planning approach. This shift has the potential to significantly enhance composite manufacturing capabilities and outcomes.
