An easy-to-understand explanation of the joining methods for CFRP (FRP) and the design and evaluation methods for joints!
At Sanko Seisakusho, which consistently handles everything from design, molding, processing, to assembly of composite materials such as CFRP (FRP) and general-purpose plastics, we are currently offering a free technical booklet titled "Basic Knowledge of CFRP 3," which condenses our molding know-how! The booklet includes explanations on FRP bonding, representative bonding methods, design of bonded joints, evaluation methods, types of adhesives, and surface treatments. It is easy to understand for beginners and can also be used as training material! 【Contents】 ■ Representative bonding methods (bolts and nuts, welding, adhesion, etc.) ■ Design of bonded joints (adhesion section) ■ Representative evaluation methods (tensile adhesive strength, tensile shear adhesive strength, etc.) ■ Types of adhesives, how to choose, and how to use them *For more details, please refer to the catalog. Feel free to contact us with any inquiries.
