Friction Bit Joining of Materials Using a Friction Rivet ID: 2017-086

A novel method for joining materials through a unique process involving friction rivets and friction stirring.

Technology Overview

This technology introduces an innovative approach to materials joining, leveraging the principles of friction to create strong, reliable bonds between workpieces. The method employs a friction rivet equipped with a cutting tip to penetrate the materials, which then bonds securely to a friction cap, ensuring a durable joint. An alternative version uses a hollow cutting tip to form an integral rivet cap upon flaring, offering versatility in application.

Key Advantages

• Provides a robust and durable bond between different materials
• Enables joining without the need for additional adhesives or soldering materials
• Offers flexibility in application with the option of a hollow cutting tip for integral cap formation
• Streamlines the joining process through the use of friction, making it efficient and cost-effective

Problems Addressed

• Eliminates the need for external bonding agents, reducing material costs and potential environmental impact
• Addresses the challenge of joining dissimilar materials, expanding the scope of manufacturing capabilities
• Overcomes limitations associated with traditional welding or adhesive methods, such as thermal distortion or bond weakness

Market Applications

• Automotive manufacturing, for joining lightweight materials to improve fuel efficiency
• Aerospace industry, where strong, lightweight joints are critical
• Construction and infrastructure, especially in applications requiring the bonding of dissimilar materials
• Medical device manufacturing, where precision and strength of joints are paramount
