Launching a high-trajectory design golf club

Yonex golf club

At the end of April 2020, Yonex released the Royal EZONE Extra Spec drivers in the Royal EZONE series. The Royal EZONE series is developed in-house with a focus on increasing the flight distance for "awakening the confidence of the flight", using precision carbon technology at the company’s Japanese factory.
The length of a conventional Royal EZONE driver is 116.84 cm, whereas this product has a short shaft length of 116.20 cm and a light balance point. This results in a high meet rate and a light swinging feeling. By designing the centre of gravity angle and the depth of the centre of gravity optimally, it leads the tee shot to a high trajectory with a good grip.

The head uses a carbon dome crown and a power groove structure that combines a new-generation carbon, Namd, to enhance the deflection and restoration power, and the full repulsion face extends the flight distance even on off-centre hits. Namd is a composite technology developed by Nitta that uses carbon nanotubes nano-dispersed into carbon fibres.
The Royal EZONE Extra Spec's special shaft uses two types of high-spec carbon: Namd, a new-generation carbon that excels in large bending and quick return, and M40X, a next-generation carbon fibre developed by Toray Industries that combines strength and elasticity. Taking advantage of each material’s characteristics, the shaft bends faster to increase the ball’s initial velocity, receives the impact at the time of impact, and gives strong flight to the ball.

DJK supporting material development

DJK outsourcing
As an institution for polymer material research, testing, and evaluation, DJK Corporation has been meeting manufacturer demands such as support for basic research in material and product development. Established in 1964 as the Japan Resin Research Institute (Dainihon Jyushi Kenkyujyo), it has been supporting research and development of polymer materials for 56 years.

The outsourcing of basic research by manufacturers has been increasing recently. Originally, the company was not widely advertised as a third party and outsourcing agency.
In recent years, developments such as cellulose nanofibres have been evaluated in line with current trends. There are also many studies devoted to carbon fibre-reinforced plastics. As the automobile industry aims to reduce weight, metal substitution is progressing, and there are many studies evaluating resin durability, leading to high expectations in the near future.

X-ray camera for non-destructive inspection of thin and light materials

Hamamatsu Photonics released the C15400-30-50A, a TDI (Time Delay Integration) X-ray camera with improved sensitivity to low-energy X-rays. The camera can take high-contrast transmission images of thin materials such as aluminium (Al) alloy sheets and light materials such as carbon fibre-reinforced plastics (CFRP). Improved inspection accuracy can be expected by incorporating it into in-line non-destructive inspection devices for industrial products and foods.

For this product, the company adopted a new method to detect low-energy X-rays and reviewed the design to more easily detect the light generated by the irradiation of low-energy X-rays. While the contrast of conventional products decreases when the X-ray energy is under 40 keV, the new product can capture transmitted images with X-rays near 20 keV with high contrast. For example, it can be used to detect hair caught in the adhesive part of a food packaging material using a thin Al alloy sheet, uneven thickness of the Al alloy sheet, uneven application of adhesive on CFRP parts, etc.

A high-performance photodetector manufactured by the company was also used to improve the signal readout speed. The maximum reading rate is 1.8 times faster than conventional methods. The recommended use range is about 25 to 110kV in X-ray sensitivity. Foreign material can be detected even in an object that combines a thick material, that does not easily transmit X-rays, and a thin material, that easily transmits them. External dimensions: width 450 x depth 1000 x height 210 mm.
The price is approximately USD30,800 excluding tax (JPY 3.3 million). The company will proceed with the development with the aim of downsizing and expanding the imaging range.

Development of a non-flammable FRP material

A non-flammable FRP has been developed by Each DreaM, a Japanese company that specializes in the manufacture of FRP materials.
FRPs are reinforced plastics that combine fibres such as glass or carbon fibres with an epoxy or phenol resin for improved strength. They are used for hulls and building materials for theme parks, for instance.

Non-flammable FRP
With this material, it becomes possible to build a fire-resistant house at low cost by using incombustible FRP from the beginning. The company is also thinking about the possibility to build floating houses to save lives in case of tsunamis.
Tested at 1200°C using a burner, the material is able to withstand flames up to 1500°C. Since it does not burn, it does not generate toxic gases. Especially for heavy equipment and automobiles, manufacturers are compelled to comply with emission regulations for diesel vehicles and automobiles by 2022. In order to clean out the exhaust gas of a combustion engine, a high horsepower is required; so a material that can withstand high heat is essential.
Each DreaM is continuing negotiations with major manufacturers interested in non-combustible materials. Moreover, government agencies are paying attention to this material, and are repeatedly testing it for practical use.
The non-flammable materials developed by Each DreaM include FRPs, heat insulation materials, paints, and fire protection liquid products. In addition to the fact that they will not burn, just by applying paint they can save the lives of many people by preventing accidents or fires.
