Ruckus Composites launches composite bicycle science program, identifies upcoming research 

Ruckus Composites (Portland, Ore., U.S.) focuses continuously on setting the standard for the inspection and repair of carbon fiber bicycles; so far, more than 16,000 bicycles have been studied. Recently, the company launched a cutting-edge carbon bicycle science program that uses chemistry, physics and engineering to investigate important questions in fields including sustainability, design, maintenance and repair. This program is designed to provide information for scientists, bicycle technicians and consumers.

Highlights of the program thus far include:

• Analysis of the carbon footprint of carbon frame repair at Ruckus Composites showing that repair produces up to 95% fewer greenhouse-equivalent gas emissions than replacement.
• Publication of a scientific paper and video presentation, “Ultrasonic Testing of Carbon Fiber Bicycles,” at the International Ultrasonics Testing Online Conference 2021. This paper/video ranked in the top ten most-viewed at the conference.
• Experiments using droplet contact angles to determine the best methodology for surface preparation of carbon fiber composite for bonding with substances such as adhesives and paint. Proper surface preparation is vital for safe repairs, says the company.

Ruckus Composites also identifies some additional topics in the pipeline in 2022 which include:

• Drop impact testing of carbon fiber frames. This is a tool drop study to determine if any damages can occur from dropped tools.
• Galvanic corrosion, where the company is even creating a “sweat bath” for certain components. 
• Exploration of epoxy and carbon fiber to gain general knowledge on material.
• Torque in the context of bicycle repair. According to Ruckus Composites, it will be using a calibrated, highly accurate (0.2%), low-range digital torque wrench to squeeze and crack tubes with precision.
