The ninth batch of EAE students from Yifa went to Germany to participate in training and examinations

In March 2024, Yifa Bonding and Composite Materials Research Institute organized the ninth batch of European Bonding Engineer EAE trainees to go to the Fraunhofer IFAM Institute in Bremen, Germany for the last two weeks of study and graduation examination of the European Bonding Engineer EAE course. Yifa Bonding and Composites Research Institute is the exclusive strategic partner of German Fraunhofer IFAM in China.

In the course, a wealth of theoretical knowledge such as bonding, adhesion, and cohesion are arranged, as well as experimental courses combined with theory, and the most advanced element analysis and surface wetting performance evaluation of the Fraunhofer IFAM Institute are also learned. Use of equipment. Throughout the learning process, students and teachers actively interacted and communicated, and conducted in-depth discussions on the use of spectral analysis technology, the principles of adhesion theoretical knowledge, and the practical application in their own work.

EAE students studying in theoretical courses

In the seventh and eighth weeks, theoretical knowledge such as the adhesion theory of bonding, the adhesion energy of bonding, the adhesion model of bonding, and the polymer behavior at the interface between polymers and inorganic materials were learned; Analysis technologies for detecting material surfaces include XPS, AES, TOF-SIMS, EDX, OSEE, etc.; I learned surface quality assurance methods, the impact of corrosion behavior on bonding quality, and surface wetting performance detection methods.

In addition to theoretical study, students were also organized to enter the laboratory to make lap shear samples bonded with different adhesives, and the surface tension and contact angle of the substrate were tested. After the lap shear samples were cured, students were organized to test the tensile and shear strength. Analysis of testing and failure modes.

After the completion of the graduation examination, the college organized a graduation dinner. Dean Fraunhofer IFAM was invited to attend the dinner and delivered a speech. The dean wished everyone a successful eight-week theoretical study, examination and final oral examination defense, and expressed his wish to obtain the European Admissions Certificate. Obtaining the Engineer EAE Certificate is a new starting point for everyone in the world of bonding. I hope that all students can make good use of the resources around them to better develop and improve themselves, and at the same time apply the knowledge they have learned to their own work. After the speech, the dean issued a completion certificate and exclusive seal to each student who passed the exam.

During the graduation dinner, Dean Fraunhofer IFAM attended and delivered a speech and issued certificates to the students.

For more than ten years, Yifa has introduced EN17460 (formerly DIN6701) and DIN2304 bonding standards into China, starting from the rail industry, covering aviation, automobiles, home appliances, electronics, shipbuilding, construction and other fields, helping the manufacturing industry to establish and improve bonding applications The technical standards in the field have made an indelible contribution to the quality assurance of Made in China. Conduct EN17460 and DIN2304 certification audits, project support and consulting in China; carry out bonding training and examinations at three levels of EAE European Bonding Engineer, EAS European Bonding Technician, EAB European Bonding Operator issued certificates by Fraunhofer, as well as composite materials Design Composite-D, Manufacturing Composite-M, Maintenance Composite-R, and Technician Composite-S training and examination. Special training courses related to customized bonding and composite material applications are also provided.
