Evaluating AFP Feasibility for a New Component.
A structured way to decide whether Automated Fiber Placement is the right route for a part, and what information settles the question quickly.
Start With the Part, Not the Process.
AFP is valuable where controlled fibre orientation on a curved surface matters and where automation pays for itself. It is not automatically the cheapest or best route. Feasibility means testing the part against what the machine, the material and the economics allow.
Six Questions in Order.
- GeometryCan the head reach every surface? Check concave radii against the compaction roller, deep pockets, flanges and any collision between head, robot and tool.
- Fibre pathsDo the design's fibre angles require steering? Tight steering radii are linked to wrinkling, and converging paths create gaps and overlaps that must be managed.
- Ply boundariesCan ply shapes be produced with the head's cut and restart capability and its minimum course length, both of which are machine-specific?
- Size and envelopeDoes the part fit the working envelope, including robot reach, any linear track and the tool positioner?
- Material and processingIs a qualified material available in a form the head accepts, and what consolidation or cure follows placement?
- Volume and economicsDo the production rate and part cost justify programming, tooling and process development against alternative processes?
When Another Process May Be Better.
Simple flat laminates
Large, flat or gently curved plies may suit automated tape laying or manual layup with cut plies.
Axisymmetric high volume
Small, high-volume cylindrical parts often favour processes designed for rotation, such as winding.
Very small or intricate parts
Short courses and tight features can exceed what a head can place efficiently.
What Speeds Up a Feasibility Review.
- 3D CAD of the part and, if available, the tool surface
- Ply book or laminate definition with fibre angles
- Material specification or approved material list
- Loads, environment and acceptance criteria
- Expected annual volume and first-order quantity
- Applicable standards and qualification route
A Feasibility Answer Should Come With Its Evidence.
A useful feasibility review states what was checked, what is still uncertain and which trials would remove the uncertainty. That is the format DANTA uses for its engineering and feasibility enquiries.
