Abstract
Most of the waste disposed of in the automotive interior parts production process are landfilled or incinerated due to the composite nature, which is difficult to recycle. If floor materials, which are typical fiber-resin multilayer automobile parts, can be separated into the resin and fiber components, a high level of recycle can be achieved. We decided to launch a project to apply the high-speed centrifugal beating method and develop a technology using floor materials as the specific model. By setting the beater screen diameter to 5 mm and peripheral speed to 110 m/s and adding a fiber-component re-beating process, the 96% purity of PE and 74% recovery rate were achieved. The recycled PE pellets were added to the currently used conventional material by 40% to fabricate prototypes in the primary-carpet fabric production line. It was confirmed that the production of primary carpet fabric was obtainable and the prototypes met the moldability and quality standards.
