Yonex Japan, a Tokyo-based sporting goods manufacturer, announced on December 14A lightweight and high-strength carbon fiber bicycle frame was developed using a composite carbon fiber material with three-dimensional carbon nanotubes evenly dispersedWhile satisfying the high strength, the weight of the structural parts is reduced by about 10% compared with traditional materials, making it weigh only 590g.
For a long time, Yonex's CarbonEx carbon fiber bicycle products have been widely loved by the public, and after improving the weight reduction effect and cruising performance, the "CarbonEx" carbon fiber bicycle products will be released in late March 2024. The product was developed with the concept of "running faster and more comfortable". While inheriting and carrying forward the technology of carbonexThe use of a new carbon fiber material has improved the weight reduction effect and improved the rigidity, repulsion, and bounce-like driving ability (acceleration).
The new material used in the newly developed carbon fiber frame is named 2G-NAMD Speed (TourgeenAMD Speed), which is a type of material developed by Nita Co., Ltd. of Japan"Homogeneous composite of nano-dispersed carbon nanotubes with carbon fibers".technology, while2G-Namd Speed is a material that evolves the carbon nanotube layer structure of Namd into a three-dimensional structure。By using 2G-NAMD material, the ability of the bicycle to recover from deformation can be dramatically improved.
The material has the same stiffness as the regular version of the carbonex material under static conditions, but the amount of warpage increases significantly when driving, and as the warpage return speed increases, the force of the pedals can be effectively converted into propulsion.
At the same time, in a higher dimension of performance, it can balance toughness and resilience by using the company's unique nanomaterial Nanometric DR in an interlayer configuration, which can reduce the weight by about 10% compared to previous products while improving strength. Based on the above technology, the lightest weight of the bicycle model processed by the company is only 590g.
Three major innovations of new products
1) The use of 2G-NAMD Speed new material significantly improves the acceleration
2G-NAMD Speed is oneA new material with a three-dimensional carbon nanotube structure is attached to the high-performance carbon fiber, the main features of which are:Resilient performance while remaining resilient。When applied to the seat bracket, it not only maintains the same rigidity as conventional materials, but also contributes to an increase in the amount of warpage while driving, and the warping return speed is also increased, thereby improving the best force and acceleration when driving.
2) Nanometric DR (nano-scale DIEL), which is high strength and lightweight, is used
The company's unique nanomaterials are used in the front triangle, chain, fork and other structural parts of the bicycle, and it can achieve a weight reduction of about 10% compared to conventional products while improving strength.
3) Based on the long-term technical advantages of YONEX company
This product inherits the technology of traditional carbonex products. The lightness and rigidity of the company's carbon material technology, combined with the high vibration attenuation to suppress the burden on the body, enable comfortable driving.
