Recep Yaldiz (Staff Scientist, Advanced Thermoplastic Composites, SABIC Specialties, The Netherlands) obtained his MSc degree from Delft University of Technology, Aerospace Engineering (departments: Constructions & Computational Mechanics + Production Technology). After that, he worked about a year at AIRBUS in Germany on the development of A380 double deck aircraft. He then returned back to the Netherlands and worked 4 years at DSM as an Application Development Engineer. Recep joined SABIC in January 2008 and worked on development of applications with thermoplastic composites. Since January 2017, he is the focal point from SABIC for the Airborne partnership as the program & project manager targeting development and implementation of Digital Composites Manufacturing Line (The first full Industry 4.0. solution for TPCs).



Mass-scale production of Composites via Automation and Digitalization - DCML "A breakthrough technology to address an industry need"



Thermoplastic composites are increasingly being considered for large volume applications that involve replacing incumbent materials such as metals. The Consumer Electronics space in particular, offers an interesting opportunity to capitalize on the performance of fiber-reinforced composites because of the general need to go to thinner structures while being frugal with changes in weight in applications like mobile computing and communications [1, 2]. These applications tend to lean towards a large part build volume, typically in the range of a million parts per year.  The model platform also tend to be short lived, which means there is a constant need to stay on top of what the customer's perceived needs are and adapt accordingly with new models. This makes the designed flexibility of the manufacturing line very important. All of this creates the perfect opportunity to explore automation driven production approaches. The development challenges however for this automation driven production approach were identified to be: high speed production, with minimal scrap and minimal human intervention resulting in low conversion costs, while still maintaining a high degree of flexibility [2].

An end-to-end automated manufacturing line in which all steps are integrated and automated into a consolidated system, thus producing a constant production flow was developed through a partnership between Airborne and SABIC. In many cases, automation technology is developed separately from material development community, yielding sub-optimal results. Here we take a holistic view and develop the most effective technology taking into account all these aspects, in material development, automation and product design. The technology developed is also suited for high-end products in other markets, such as automotive, aerospace or sporting goods.  

The ultimate goal of this line is to be fully digital and designed for minimal human intervention. It features full in-line inspection of the input material as well as the finished part. This information is processed in real time allowing online process optimization to adapt the process settings on-the-fly, based on the measured data and required output quality. Ultimately, this can deliver flexibility in order to accommodate changes that the industry demands.
