The 2022 Winter Olympics has once again set off the ice and snow equipment fever
Composite materials reduce weight and strengthen snowboards
Composite materials reduce weight and strengthen snowboardsIf you want to "float" on snow, lightweight, high-strength and low-damping skis are indispensable!
In the past, most of the snowboards were just a piece of wood.
It is understood that, in addition to common wood cores, polyurethane can also be used to make snowboard cores
To reduce the vibration of skis during exercise, snowboard brands such as Faction, Salomon and Whitedot Skis are increasing the flax content in their composites
The bottom of the board is made of P-Tex polyethylene plastic
There are usually two processing methods for the bottom of the plate, one is extrusion and sintering
The bottom of the extrusion plate is to melt polyethylene particles at high temperature and then press them into a suitable thickness and cut them into a certain shape
In addition, in order to reduce the carbon footprint of the snowboard manufacturing process, the addition of bio-based and recycled materials has also been key in recent years for ski brands to fulfill their sustainability commitments
At present, the world's major snowboard manufacturers are Burton in the United States, Lib Tech, GNU, Arbor, Salomon in France, ENDEAVOR in Canada, and FACTION in Switzerland
Su Yiming's snowboard in the men's snowboard steeplechase competition is the Burton snowboard
Among them, Burton's first-tier snowboard supplier in China is Kunshan Fusheng Sporting Goods Co.
Impact resistant eye protection for polycarbonate ski lenses
Impact resistant eye protection for polycarbonate ski lenses
Ski goggles should have the following functions: first, to prevent eye irritation from cold wind; second, to prevent ultraviolet rays from burning eyes; third, the mirror surface should not fog; fourth, ski goggles should not cause damage to the face after a fall
In order to achieve these protective functions, the choice of lens material is particularly important
For example, the lens of Oakley ski goggles is mainly made of high-purity polycarbonate Plutonite, which has 100% UVA, UVB and UVC protection layers built into the lens instead of coating
Oakley ski goggles
.
According to reports, Oakley ski lenses are processed by injection molding.
Polycarbonate particles are first added to melt at high temperature and injected into the lens mold.
After high-pressure injection molding, cooling and demoulding are performed.
The lens can be produced in just a few minutes

Aerospace-grade carbon fiber helmets reduce weight and crash
Aerospace-grade carbon fiber helmets reduce weight and crashThe exclusive helmet for the Chinese team's snowmobile project was developed by Dongguan Institute of Technology
.
According to reports, the Dongguan project team integrates 3D scanning, design, and 3D printing technologies, collects data on athletes, and conducts one-to-one customization to achieve the effect that can fit the actual needs of each athlete
.
Dongguan Institute of Technology is responsible for the research and development of the exclusive helmet for the Chinese team snowmobile project
.
In terms of the use of materials, this custom snowmobile helmet is made of China Aerospace T800 carbon fiber and pure carbon fiber materials with high strength and excellent anti-collision performance.
grams, only about 1100 grams, effectively reducing the weight for athletes
.
While reducing weight, the inner material buffer layer of the helmet also adopts a 3D printing lattice structure, which can resist various impact forces of the helmet when it encounters a collision, and better protect the athletes
.
In addition, the helmet has also been greatly optimized in wind resistance and lens anti-fog
.
