Robotic Fiber Placement Composite Layup Patents 2026
Robotic fiber placement is at an inflection point in 2026, driven by aerospace demand for defect-free lightweight structures and the convergence of intelligent process control with digital tools. This dataset spans filings from 2002 to early 2026 across AFP workcell architectures, AR-guided layup, and ceramic matrix composite automation.
AFP and Robotic Layup: From Workcell Architecture to Intelligent Quality Control
Automated fiber placement (AFP) and robotic fiber placement (RFP) systems deposit continuous fiber tows, slit tapes, or woven prepreg materials onto mandrels or molds via computer-controlled robotic arms with specialized end-effectors. Within this dataset, the field subdivides into AFP multi-tow deposition heads, robotic layup cells where the tool moves relative to a fixed head, AR-guided human layup, and multi-robot or mobile platforms.
The earliest filings in this dataset date to 2002–2005, establishing foundational AFP concepts including on-the-fly high-speed event control during fabrication and visual inspection of deposited tows. System architecture patents from 2010–2016 defined workcell philosophies — most notably Fives Machining Systems’ stationary dispensing head concept (2012, EP) and Boeing’s high-rate barrel-format AFP system (2016, US/EP).
The 2017–2022 period introduced digitalization signals: Siemens’ augmented reality ply layup patents (2019, WO/EP/US) brought digital twin concepts into the laminator’s field of view, while BAE Systems filed an enhanced AFP method incorporating laser-ablated fiber discontinuities for tow steering (2022, GB). University of Southern California began publishing on hybrid prepreg composite sheet layup under DoD and NSF contracts during this period.
The 2023–2026 frontier in this dataset is defined by in-process defect detection, dual-mode rework AFP, ceramic matrix composite layup automation, and CAPP-AFP integration. In retrieved records, Boeing is the most prolific assignee with at least 12 distinct patent documents, followed by Siemens with at least 5 active documents in the AR-guided layup segment and University of Southern California with at least 5 documents covering hybrid prepreg, path planning, and CMC layup cells.

Frequently Asked Questions: Robotic Fiber Placement and AFP Patents
Within this dataset, AFP refers specifically to multi-tow deposition heads guided by robotic arms that perform cut, add, and restart operations on complex curved surfaces, as demonstrated in Boeing and Ingersoll Machine Tools filings. Robotic fiber placement (RFP) is the broader term encompassing AFP, robotic layup cells where the tool moves relative to a fixed head, and mobile robotic layup platforms. Both terms appear across the retrieved patent documents.
In retrieved records, The Boeing Company is the most prolific assignee with at least 12 distinct patent documents spanning 2010–2026. Siemens (Siemens Industry Software Inc. and Siemens Product Lifecycle Management Software Inc.) holds at least 5 active documents in the AR-guided layup segment. University of Southern California appears with at least 5 documents (2018–2025). Spirit AeroSystems and Siemens Gamesa each have 2 documents in this dataset.
The stationary dispensing head concept was pioneered by Fives Machining Systems, with a core EP filing in 2012 and related US filings under Wells Fargo Bank as security interest holder (2011, 2014). In this configuration, the creel and dispensing head are fixed to a stationary arm, and the robot wrist manipulates the layup tool. This keeps fiber path length constant, solving the variability introduced when the head itself moves.
