Abstract
As for recent market needs, there is an increasing demand for the total coordination of the vehicles interior trims, the enhancement of adaptability for freer designs, soft touch and weight reduction. In order to meet these demands, we have developed a door trim reflecting this new concept. This door trim is manufactured by foaming rigid polyurethane foam as the core material after the double slush skin (1st layer: PVC, 2nd layer: PVC foam) and the glass mat are set together in the foaming mold. Employment of double slushed skin allows an improvement in flexibility of design, softer materials to be manufactured and further coordination of color, gloss and grain pattern with those of instrument pad. In addition, we have succeeded in reducing the weight by using glass mat reinforced rigid polyurethane foam. Since the center ornament fabric is formed together with the skin, the look at the joint section of the fabric and skin has been improved remarkably compared to conventional products.
We also succeeded in reducing the number of processes by abolishing the ornament assembly process and by improvement in the treatment of periphery and terminal of parts.
