Huvis, a company specializing in chemical fiber materials, announced on the 19th that it has jointly obtained a new technology certification (NET certification) with Hyundai Motor and Hado FNC for "modified PET nonwoven fabric manufacturing technology for undercover to reduce automobile engine noise and road noise."

New technology certification is a certification system organized by the Korea Industrial Technology Promotion Association and is granted to the first new technology developed in Korea. The purpose is to help enter the initial market by promoting the commercialization and technology transaction of new technologies and enhancing the reliability of products applied with new technologies.

This new technology-certified product is a nonwoven fabric material for undercover to reduce noise generated when driving on the road.

Recently released vehicles usually use glass fiber reinforced boards to install undercover at the bottom of the vehicle to reduce noise during operation. However, due to the nature of glass fiber, it is heavy, generates dust harmful to the human body during production, and has the disadvantage that it cannot be recycled.

The PET nonwoven fabric undercover material developed by Huvis with Hyundai Motor and Hado FNC is said to be light, has improved NVH (noise, vibration, shock) performance, and is eco-friendly because it can be recycled.

By applying copolymerization technology to "Low Melting Fiber (LMF), a thermal adhesive material for Hubis vehicles, stability and fluidity were provided to prevent deformation at a certain temperature, and LMF specialized for undercover was developed. Huvis explained that manufacturing nonwoven felt with the material reduces weight by 15% and increases strength by 20% compared to conventional glass fiber reinforced boards, as well as improves sound absorption performance by nine times.

CEO Shin Yoo-dong of Hubis said, "LMF is a product that can be applied to various fields such as architecture and interior design in addition to automobiles, and due to the nature of polyester, it can be recycled."

Meanwhile, Hyundai Motor plans to gradually apply LMF-applied undercover to new models from 2020.
