Areas of application

Shipbuilding

In order to achieve lightweighting of automobiles, effectively reduce costs and fuel consumption rates, major automobile companies generally adopt optimization design methods to design cars, making the materials used for large car coverings thinner and thinner. To solve the problems of insufficient local strength and stiffness caused by this, various reinforcement materials have been developed and widely used in various types of automobiles.
