Article: “Nondestructive Evaluation of Carbon Fiber Bicycle Frames Using Infrared Thermography”
Abstract: “Bicycle frames made of carbon fibre are extremely popular for high-performance cycling due to the stiffness-to-weight ratio, which enables greater power transfer. However, products manufactured using carbon fibre are sensitive to impact damage.
“Therefore, intelligent nondestructive evaluation is a required step to prevent failures and ensure a secure usage of the bicycle. This work proposes an inspection method based on active thermography, a proven technique successfully applied to other materials.
“Different configurations for the inspection are tested, including power and heating time. Moreover, experiments are applied to a real bicycle frame with generated impact damage of different energies. Tests show excellent results, detecting the generated damage during the inspection.
“When the results are combined with advanced image post-processing methods, the SNR is greatly increased, and the size and localization of the defects are clearly visible in the images.”

“This article belongs to the Special Issue Intelligent Sensing Technologies for Nondestructive Evaluation
“Nondestructive evaluation (NDE) sensing has progressed significantly in the past few years. Especially, smart sensors play an increasingly important role in structural damage detection efforts. There is growing progress in the performance of strategic sensors, such as piezoelectric sensors, as well as noncontact sensors, such as air-coupled transducers, magnetic flux leakage sensors and pulsed laser ultrasonic propagation applications.
“The most progress has been made in the development of use and application software for all technologies. We are now able to enhance damage resolutions and then focus on damage visualization in many applications.
“This Special Issue aims to highlight advances in the development, testing, and use of damage visualization tools for smart sensor-based nondestructive evaluations. Topics include, but are not limited to:
- New developments in smart sensing-based nondestructive evaluations
- Magnetic flux leakage sensors
- Laser scanning-based ultrasonic propagation sensors
- Piezoelectric sensors
- Air-coupled transducers
- Damage detection and visualization”
