The 21st century will be the era of composite materials. The composite materials are strong designability. The organic combination of different materials and different structures can complement each other and blend with each other, making the products more lightweight, high-strength, low-cost, anti-corrosive and durable. Expanded the performance and development space of new products. Yorde , which is aiming at environmental protection, is committed to the application and promotion of composite materials, and make the materials consumption less with technology, the performance is better, and the environmental cost is smaller, so as to achieve the coordination of environmental protection and economic development.
