Application Case: AFP-XS, the Flagship Compact Automated Fiber Placement System

General Introduction

AFP‑XS is Addcomposites’ flagship automated fiber placement system, positioned as a versatile, compact, high‑precision automation solution tailored to the R&D testing, small‑batch production, and custom component manufacturing needs of composite materials. It is also the mainstream compact AFP platform, with over 50 units currently in operation. Built on a highly compact architecture, the system integrates key features such as high‑precision placement, multi‑process compatibility, and flexible deployment, overcoming the traditional limitations of large footprint, high cost, and complex installation associated with conventional AFP equipment. As a result, it is well suited for laboratory settings and small to medium‑sized production facilities. The core strength of AFP‑XS lies in its “small but refined” design: the system boasts a compact footprint and lightweight construction, enabling integration with collaborative and industrial robots without requiring dedicated large‑scale workspaces. At the same time, it delivers placement accuracy comparable to that of larger AFP systems, meeting the stringent precision requirements of R&D and small‑batch production.

As Addcomposites’ flagship product, the AFP‑XS integrates automated fiber placement (AFP) with filament winding, enabling a single machine to perform both processes and significantly enhancing equipment utilization and process versatility. The system is equipped with the company’s proprietary AddPath software, which provides integrated capabilities for path planning, simulation, and real-time monitoring, allowing R&D teams to swiftly translate design concepts into production‑ready layup operations. Currently, the AFP‑XS has been adopted by composite‑material research institutions and small‑to‑medium manufacturers, serving as a critical tool for composite material development and low‑volume custom production. It supports diverse applications across aerospace, defense, marine, and materials‑research sectors, lowering the barriers to adopting advanced composite manufacturing technologies for both industrial enterprises and academic research organizations.

Working principle

The AFP‑XS operates by integrating two advanced manufacturing techniques—Automated Fiber Placement (AFP) and filament winding—leveraging high‑precision motion control and software‑driven path planning and simulation to achieve precise forming of composite components, while enabling real‑time switching between the two processes. The system’s core architecture comprises a compact multi‑tow placement head, a switchable process module, a motion‑control module, the AddPath path‑planning and simulation software, and an online inspection module. Prior to operation, users import the component’s CAD model into the AddPath software, which automatically generates the optimal placement or winding path based on the part’s geometry, material properties, and process requirements, and conducts virtual simulations to validate path feasibility and prevent interference and errors during actual production.

When the AFP process is employed, the system, based on the simulated path, uses the motion‑control module to drive the robot and move the placement head. The tow‑delivery module steadily feeds prepreg tows—supporting switching between 1‑, 2‑, or 4‑tow configurations—to the placement head. A heating unit preheats and activates the tows, while a compaction roller ensures tight contact between the tows and the mold surface, completing the fiber placement. During placement, the in‑process inspection module continuously acquires real‑time data on tow position, bonding quality, and other parameters, feeding this information back to the software for dynamic adjustments. When a switch to the filament winding process is required, no hardware changes are necessary; the process mode is simply toggled via software. The system then drives the mandrel to rotate, enabling the placement head to move axially and circumferentially along the mandrel, thereby achieving helical or hoop winding and meeting the forming requirements of axisymmetric components.

Whether using the AFP process or filament winding, the system features real-time tow‑cutting and resumption capabilities, enabling precise cutting of tows according to path requirements and resuming layup or winding at designated locations, thus facilitating the fabrication of complex geometric components. Upon completion of layup or winding, the software automatically logs all process parameters, ensuring full traceability of production data and providing a solid foundation for subsequent process optimization and product quality analysis. The entire workflow—from design and simulation through execution to data traceability—is fully digitized.

Advantages and Key Features

As a flagship compact AFP system, the AFP‑XS excels in process compatibility, deployment flexibility, precision control, and cost efficiency, while incorporating numerous technological features tailored to R&D and small‑batch production needs. A key distinguishing feature is its dual‑process compatibility: a single machine can accommodate the forming requirements of various component types, significantly boosting equipment utilization and reducing capital expenditures for both enterprises and research institutions. In terms of precision, the system achieves a repeat positioning accuracy of ±0.05 mm and delivers high positional accuracy in tape placement, meeting the stringent demands of R&D testing and custom‑made components for dimensional accuracy and fiber orientation, thereby ensuring consistent product performance.

Deployment flexibility is a key strength of the AFP‑XS. With its compact, lightweight design, the system can be mounted on collaborative robots, industrial robots, and other platforms, eliminating the need for dedicated large‑scale workspaces. It can be deployed in laboratories or small production workshops, and its installation and commissioning are straightforward, enabling rapid deployment and operation. The accompanying AddPath software integrates design, simulation, process execution, and real-time monitoring, featuring a user‑friendly interface that allows R&D personnel to quickly perform path planning and simulations without requiring specialized programming expertise, thereby significantly shortening the time from design to production. In terms of material compatibility, the AFP‑XS supports a wide range of materials, including thermoset prepregs, thermoplastic prepregs, dry fibers, and tape‑wound materials, and can be flexibly switched to meet diverse R&D and production needs, facilitating both material‑specific forming trials and small‑batch manufacturing.

In addition, the AFP‑XS offers excellent cost‑effectiveness; compared with conventional large‑scale AFP systems, it reduces both acquisition and operating costs, thereby lowering the barrier to entry for small and medium‑sized enterprises and research institutions seeking to adopt advanced composite manufacturing technologies. The system also excels in ease of maintenance: its compact design simplifies the replacement of wear parts and routine upkeep, while Addcomposites provides technical support to ensure reliable, stable operation. From a data‑driven perspective, the system enables comprehensive data recording and traceability throughout the production process, providing robust data support for process optimization and product quality analysis, thus aligning with the evolving demands of digital manufacturing.

Application Areas and Use Cases

With its multifunctionality, compact design, and high precision, the AFP‑XS is ideally suited for applications such as composite material R&D testing, small‑batch custom production, and process validation, serving a wide range of sectors including materials research institutions, aerospace R&D centers, defense‑related industries, shipbuilding and marine engineering, and small to medium‑sized high‑end manufacturing enterprises. In materials research institutes and universities, the AFP‑XS is primarily used for studying forming processes of novel composite materials and for optimizing fiber placement and winding techniques, providing essential hardware support for new‑material development. At aerospace R&D centers, it facilitates the rapid prototyping and small‑batch production of advanced components for spacecraft and aircraft, enabling swift translation of design concepts into physical parts and thereby shortening the R&D cycle. In the defense sector, it supports the small‑batch fabrication of customized composite components for weapons systems, meeting stringent requirements for lightweight construction and superior performance. In the shipbuilding and marine industries, it is employed to mold small, complex composite components, enhancing both the precision and efficiency of component manufacturing.
