What is an Automated Fiber Placement (AFP) Machine?
Automated Fiber Placement (AFP) is a sophisticated process used in the manufacturing of composite materials, where continuous fibers are meticulously placed onto a substrate using a specialized machine. This technology has been around for decades, evolving significantly over time to enhance efficiency and quality. Today, AFP is a pivotal part of various industries, known for its ability to produce composite parts with superior mechanical properties, extended fatigue life, and enhanced fracture toughness.
The AFP machine operates by attaching an AFP head to an industrial robotic arm, programmed to place strips of composite material tapes, or tows, onto a tool surface. This process requires precision to ensure minimal defects and optimal adhesion between the tows and the substrate. The machine utilizes heating and compaction during the placement of the tows, and tow tension is meticulously managed to ensure accurate placement. The end result is a laminate, composed of multiple plies stacked together in a precise sequence.
The use of automation and robotics in AFP not only accelerates production but also ensures improved accuracy, quality, and a reduction in human error, making it an invaluable asset in composite manufacturing. Operators of AFP systems generally need a basic understanding of composites processing and CNC machine operation. The programming and operation of the machine involve several steps, including part production simulation, NC code generation, machine setup, and careful monitoring during the layup process.
AFP machines have found applications in various industries, such as aerospace for manufacturing aircraft components, automotive for composite parts, construction for materials like bridge decks and beams, and wind energy for composite wind turbine blades. The versatility and precision of AFP machines make them a valuable tool for manufacturing lightweight, complex-shaped structures optimized for load-carrying and efficiency.
Understanding the Cost Components of an Automated Fiber Placement (AFP) Machine
Material Handling
Thermoset Materials: These materials require careful handling, often needing slight heating above room temperature for optimal placement, yet must be kept below certain temperatures to prevent premature curing.
Thermoplastic Materials: These materials are non-tacky at room temperature and require heating to their melting point for proper bonding. This may necessitate additional equipment such as external heating units.
Dry Fiber: These materials are also non-tacky and are used as precursor methods to RTM-like infusion methods to achieve a higher rate of production. The Dry fiber tapes often contain a thermoplastic binder in the form of viel, powder, or thread that is heated and helps with the tack during placement
Number of Tows: In the majority of the cases selecting a single tow system with variable width support is sufficient. However in order to achieve a higher production rate over complex geometry multi-tow fiber placement heads are preferred.
Temperature Control
Proper application of heat is crucial for ensuring the effective adhesion of the composite materials. Various heating systems are available, each with its own set of characteristics. Infrared heaters are commonly used, but they may have drawbacks such as inefficient and non-uniform heat transfer.
Process Types
The AFP machine should be versatile enough to accommodate different manufacturing processes, including fiber placement, tape laying, and filament winding. This ensures adaptability to various part shapes and sizes.
Motion Platforms:
The choice of motion platform depends on the size and shape of the parts being manufactured. Options include horizontal gantries, vertical gantries, and robotic arms, each suited for specific applications.
Software Integration and Process Planning:
The software used in AFP operations plays a critical role, acting as the intermediary between design, manufacturing, and quality control. A well-integrated software solution ensures efficient process planning and operation.
Support and Maintenance:
Given the complexity of automated systems, consistent support from the Original Equipment Manufacturer (OEM) is essential. This includes updates for firmware, planning software, operations, and the provision of spare parts for a significant period, typically at least 10 years.
By understanding these cost components, manufacturers can make more informed decisions when selecting an AFP machine, ensuring they choose a system that meets their specific needs and budget.
Price of Traditional Large AFP Machines
Automated Fiber Placement (AFP) machines, particularly those used in the aerospace industry for large, expensive parts, are typically custom-built. This customization is a significant factor in the pricing of these machines, making it a complex aspect to quantify. However, we can identify the main cost drivers and provide a general understanding of the pricing structure.
Main Cost Drivers:
Engineering Costs: The technical complexity of AFP machines is a major cost driver. This complexity varies based on the size and complexity of the part being manufactured, as well as the speed of tape or tow placement.
Market Dynamics: The AFP machine market is characterized by a small number of consumers (typically airplane manufacturers or the military) and suppliers. This leads to nearly full customization of each machine, contributing to the high costs.
Customization: Added features and modifications to a basic machine will increase the overall price. Common customizations include changes in length, width, or adaptations for national safety regulations. For example, the incremental cost for adding 10 feet in the width of the machine is approximately $100,000.
Pricing Examples:
Manufacturer A:
A tape laying machine capable of making parts as large as 25' x 120'.
Base price: $3,500,000.
With additional features (software, postprocessor, part history recording, installation): Approximately $4,182,000.
A machine half the size would cost 5-7% less.
Manufacturer B:
A tape laying machine 16 feet wide, capable of making parts up to 140 feet long.
Base price: Approximately $2.5-$2.6 Million.
With all features included: $4.25-$4.8 Million.
An addition of 20 ft in width would increase the cost by $200,000.
Manufacturer C:
A fiber placement system capable of placing up to 32 tows of 0.125" width at a speed of up to 1200 in/min.
Price range: $4.5-$6 Million for a machine with a travel of 30' x 28.5' x 5'.
These examples illustrate the significant investment required for traditional large AFP machines, with prices ranging from $3 Million to $6 Million, depending on the size, capabilities, and additional features of the machine. It is crucial for manufacturers to carefully consider their specific needs and budget when selecting an AFP machine, as the cost implications are substantial.
