Application of Adhesive Quality Management System in Carbon Fiber Composite Materials

Carbon fiber composite materials are widely used in industries such as aerospace, rail transportation, and leisure sports due to their significant advantages of lightweight and high strength. The connection technology of carbon fiber composite components is also one of the current focuses of attention. Considering the particularity of carbon fiber composite materials, bonding has become one of the main means of connecting carbon fiber composite materials. Whether it's the C919 aircraft, high-speed trains, new energy vehicles, or carbon fiber bicycles, the bonding applications of carbon fiber composite materials are everywhere.

Adhesive technology is a special process that requires a specialized quality management system to control the quality of the adhesive; Yifa Bonding & Composite Research Institute is a leader in China's adhesive quality management system. Yifa Bonding & Composite Research Institute is a strategic partner of Fraunhofer IFAM in China, with four companies including Shanghai Yifa Adhesive Chemical Technology Co., Ltd., Yifa New Materials Research Institute (Jiangsu) Co., Ltd., Yifa New Materials (Qingdao) Co., Ltd., and Shanghai Yifa Business Consulting Co., Ltd. For over a decade, Yifa has introduced adhesive standards such as EN17460/DIN6701 and ISO21368/DIN2304 into China. EN17460/DIN6701 adhesive quality management system is applicable to the rail transit industry, while DIN2304 adhesive quality management system is applicable to general industries outside the rail transit industry. After years of verification, the scale of EN17460/DIN6701 and DIN2304 adhesive quality system certification continues to expand, and the successful factors for ensuring adhesive quality are the following three points:

1. Appointing qualified personnel (professional personnel management);

2. Conduct design validation (experimental verification of design feasibility);

3. Classify levels (allocate resources reasonably).

Yifa Bonding & Composite Research Institute has always been committed to helping China's manufacturing industry establish and improve technical standards in the field of adhesive applications. At the same time, it has also trained a large number of European adhesive operators (adhesive operators), European adhesive technicians, and European adhesive engineers for China through EAB training, EAS training, and EAE training, greatly enriching the domestic adhesive talent. At present, Yifa Bonding & Composite Research Institute is also bringing training in composite repair and composite technicians to China. Through these adhesive quality management systems and adhesive training, the adhesive quality of carbon fiber composite material connections can be ensured, the connection efficiency of carbon fiber composite material components can be improved, and the application of carbon fiber composite material components can be promoted.
