“Automated Repair Patch Production for Composites” project has been completed!

ARP2 project which was a dual collaboration of Sabanci University in Turkey and RWTH Aachen University in Germany has been completed (June 2017-2020) and its final report is accepted.

The project provided a rich insight in CFRP repair in accordance with Structural Repair Guidelines and allowed us to experience the repair of primary and secondary components of aircraft in their real implementation environment thanks to Turkish Airlines Technic, in Sabiha Gokcen Airport area. Along with the project 1 undergraduate intern, 1 undergraduate student, 2 graduate interns, 1 MSc student gained hands-on experience on composite repair, 2 MSc. students graduated within the scope of this project, 2 PhD students actively participated in nanomaterial functionalization  and 3 postdocs participated in various work packages. A pilot-scale nano-integration unit was constructed and actively used for providing master batch for the nano-modified carbon fibre reinforced thermoset prepreg production line of Kordsa A.S. After the pandemic, it was possible to transfer this know-how to the Sabanci University Integrated Manufacturing Technologies Application and Research Center (SU IMC) – Composite Technologies Center of Excellence (CTCE), for the completion of aircraft repair procedures in the lab infrastructures.

Further, significant efforts were given to automatize the ply-by-ply engraving of the CFRPs with KUKA robot at the SU IMC research center with high precision with limited time constraints, which was also performed by RWTH Aachen University simultaneously.

The corresponding research articles are being prepared for publication for further exploitation of the results to the scientists, researchers and other end-users. Many thanks to our researchers, students, our collaborators Kordsa A.S. and its project leaders, Turkish Technic and aircraft structural repair unit leader, atelier leaders and technicians; and the administrative-technical staff at the SU IMC CTCE for their efforts, valuable recommendations and patience.

Citations page being updated – Stay safe & healthy during COVID-19

Recent citations to my articles are being added to my Citations page (with their DOI links) for further dissemination of knowledge for global researchers and students.

As many countries and people have been suffering severely from novel Corona virus 2019 (COVID-19) since January 2020, I am wishing health and safety to everyone and their families in all countries, and feeling the overwhelming gratitude for the medics and other supporting workers in the health sector at these difficult times.

My 1001 Research Project is accepted for funding

Good news: My research project which I proposed in March 2019 passed the evaluation in MAG (Engineering Research Group) and is accepted for funding by The Scientific and Technological Research Council of Turkey.

Our project aims for the production, modeling, characterization and testing of innovative 3D woven composite materials for the use of high performance applications.

Project team consists of Dr. Hatice Sinem Sas Cayci (Sabanci University FENS&IMC CTCE) who is an expert on resin flow optimization in complex fibrous reinforcements and Dr. Adnan Kefal (Istanbul Technical University) who has exceptional experience in finite element analysis and homogenization methods.

The project duarion is 3 years with a budget of 720.000 TL.


Good news from Aeronautics & Aviation calls: Our 1003 Project is accepted for funding

Our 3-year large-scale Aeronautics and Space Innovative Technologies project which I will be conducting as principal investigator in TUBITAK ARDEB 1003 priority area calls has been accepted for funding. In the project, Dr. Lutfi Taner Tunc (Sabanci University, IMC-CTCE) will be the supervisor of the robotics&manufacturing area; and Dr. Bertan Beylergil (Alanya Alaaddin Keykubat University) and Dr. Cem Ozturk (Kordsa A.S.) will be conducting the sub-projects, respectively.

Our project will be focusing on atmospheric plasma activation as an environment-friendly, economic and efficient method for surface treatment of high-performance composite materials used in aeronautics&aerospace applications.

284 proposals were submitted nationwide for the 1st stage of evaluation only under MAG (Engineering Research Group) section, and 17 of them are accepted after a long evaluation procedure, 4 of which belongs to our research center. Congratulations to my 3 colleagues whose proposals were also accepted (Prof. Bahattin Koc, Dr. Burcu Saner Okan, Dr. Eralp Demir; all from Sabanci University, IMC-CTCE).

The project duration is 3 years and the budget is 2.500.000 TL.
