Tailored Fiber Placement

Automated Tailored Fiber Placement (TFP) is made possible with StitchAttach™ Technology, a Robust and Automated Machine Solution for laying out Fiber Tow/Roving for Carbon Fiber-Reinforced Composites. This allows fiber to be laid out freely and selectively, thus combining Cost Benefits and Improved Product Characteristics.

Free Fiber Orientation Benefit = Peak Performance Composites
The free fiber orientation feature makes it possible to utilize the full tensile strength of the fiber during product design. The fiber can be laid out selectively and precisely in complex shapes like Circles, Curves and Arcs, and with any angle of direction, greatly boosting freedom of design.

Local Fiber Reinforcements
For optimized stiffness and strength, local reinforcement is easily achieved via selectively stacking layers of fibers on top of previously laid out fibers.

Lower Cost
By laying out Fiber Tow/Roving selectively and only where needed, Preform material cost may be reduced by as much as 75-90% vs. using braided, woven or knitted multi axial materials.

Minimizing Production Waste
By producing Near-Net Shape Preforms, material scrap during pre-form production is minimized or totally eliminated, lowering costs.

Material Combinations
Various types of materials can be combined within a single design, including Carbon, Glass, Aramid, Natural Fibers and more. These hybrid fabrics make use of the best properties of each material.

Peak Performance Composites with Tailored Fiber Placement
The relative strength of a composite layer depends on the angle (α) between the Fiber Orientation and the Direction of the Load Force within the structure. By aligning the orientation of fibers with the direction of the load force, the relative strength of a composite can often be significantly improved. See below graph.
Fiber Direction and strength
If the direction of the load force is more that 10 degrees off the actual fiber orientation, the load carrying capacity may be as low as 3-20% of the tensile strength of the fiber. With LayStitch™ Machines and Tailored Fiber Placement, the fiber orientation can be precisely fine tuned and optimized for Peak Performance Composite Strength and Stiffness.
