JEC World 2019 preview: Sika Advanced Resins
Sika Advanced Resins (Baar, Switzerland) is unveiling Ullit’s (Diors, France) composite tank for trucks that run on compressed natural gas (CNG).
Sika Advanced Resins (Baar, Switzerland) is unveiling Ullit’s (Diors, France) composite tank for trucks that run on compressed natural gas (CNG). The tank, designed with a tailor-made epoxy system designed by Sika Advanced Resins, is said to help reduce pollution in urban traffic.
The tank, which contains up to 320 L of CNG, is the same size as a conventional diesel fuel tank. According to Ullit, the resin that Sika developed for the tank is adaptable to a variety of design constraints including pressures up to 700 bar. The resin also has been designed to withstand the cyclic pressurization loads on the filament-wound tanks. In combination with carbon fiber, the resin is said to provide mechanical resistance for different tank shapes. The combination, Sika says, reduces the weight of the tank by a factor of four.
The tank is also intended to support the environment by reducing pollution. A recent study reportedly shows that the use of vehicles running on natural gas rather than diesel or gasoline helps considerably to reduce pollution. For CNG engines, the study indicates a 75-90% decrease in fine particles and nitrogen oxides. CO2 emissions are 7-16% lower, which reduces the noise of an engine by 50%.

Compared to legacy materials like steel, aluminum, iron and titanium, composites are still coming of age, and only just now are being better understood by design and manufacturing engineers. However, composites’ physical properties — combined with unbeatable light weight — make them undeniably attractive.
Lightweight, hard and stable at high temperatures, CMCs are emerging from two decades of study and development into commercial applications.
