Case Study

Application: Bonding a Carbon Bike Frame with ARALDITE® 2019 Adhesive

Gain maximum freedom in the design of carbon composite materials.

The Challenge

Bonding a carbon bicycle frame and polyamide connection parts.  

The Solution

The manufacturer had designed a very original and lightweight frame that needed to be bonded to resist with high stress. With no stiffness reduction up to 70°C, the ARALDITE® 2019 adhesive was the right fit for this job. 

To ensure a reliable solution, the customer utilized our testing and simulation services in the development of the frame. The result was a faster time to market with a superior, high-performance product.
