Product Introduction

    Glass fiber composites are the main support materials for traditional car parts. Although glass fiber has good physical and chemical properties, such as heat resistance, insulation resistance, flame resistance and weather resistance, etc., there are also disadvantages: For examples, silicon particles harmful to human body; the difficulties of waste recycling, high energy consumption, etc. With the rising environmental awareness, international brands require producers to provide the information of materials safety, recyclability, recoverability, and so on. Therefore, the above-mentioned have been taken into design concepts of a product.

    YEN SIGN has developed the Natural Fiber Composites. Bast fibers of various plants and synthetic fibers are taken as raw materials. These two kinds of fibers are put on the process and blending and needle punching so as to become the multi-layer non-woven fabric. Next, they are finished with resin and made into the natural fiber composite plates. Only then, they can be used as semi-finished materials for car parts. At the final stage, through the cutting and heat compression molding, they become the natural fiber composite materials which could replace the glass fiber composite materials.

    The application of natural fiber composite materials in the automobile industry display several advantages such as light weight, low cost, environmental friendliness, good thermal insultation, resistance to noise as well as the governmental support.Our R & D division has developed our own comb& cutting machinery which can comb the bast materials such as bananas, shellflower bast etc.into appropriate length and fineness fibers. These fibers can fully or partially replace the imports of hemp fibers such as flax, kenaf and ramie, etc. In addtion to reducing costs, applying our method can increase the supply of natural fiber sources. Most importantly, it can also improve product quality and stability.
YEN SIGN has uccesfully developed natural fiber composite materials, and now cooperate with the major domestic automobile manufacturers in the aspects of materials design and development. These natural fiber compsite materials have gone through constant product testing and process correction. Besides, they also completed vehicle roof component testing and evaluation, including a rigidity test, flame restardant testing, thermal cycling test and so on.

Applications:
Automotive interior materials: headliners, interior side panels, interior insulation (sound) boards, the trunk pallets
Building materials: doors, plywood, window frames, railings, support brackets
