摘要

Recently, interior quality has improved remarkably, mainly in European cars. The interior quality has a lot of elements in it. Recently, not only visual quality but also "touch feel" at light touch of a product surface is becoming an important element. However, there was no quantitative index of "touch feel", and the relation between "touch feel" and the composition of the resin material for interior was not also clarified. We have advanced researches for controlling "touch feel" by material composition. We have been examining a quantification of sensory factors, which corresponds to "touch feel", and physical properties which correlates closely with the sensory factors and can be incorporated into material composition. As a result, "touch feel" of plastic material can be explained with "dry and wet feel" and "soft and hard feel" and can be quantified. Moreover "friction" and "compression" properties of the resin material were substituted for "dry and wet feel" and "soft and hard feel". The measurement condition was found, especially in the "compression" property at ultra low load that has a high correlation to "soft and hard feel" of plastic material. In addition, concerning a thermoplastic elastomer (TPO), by clarifying the relation between these physical properties and TPO composition, we developed TPO which is superior in tactile sense and have adopted the material for RX-8 front armrest skin.
