Title
(EN) NET-SHAPED STRUCTURE BODY
(FR) CORPS DE STRUCTURE EN FORME DE FILET
(JA) 網状構造体
Abstract
(EN)
The net-shaped structure body has a three-dimensional random loop joined structure comprising continuous thermoplastic elastomer filaments of 0.1 to 3.0 mm fiber diameter, the continuous thermoplastic elastomer filaments having been structured as a composite from a polyester-based thermoplastic elastomer and a polystyrene-based thermoplastic elastomer. The net-shaped structure body has a 70°C compressive residual stress of 35% or lower, and a rebound resilience of 10% or lower. In this manner, a net-shaped structure body is provided, which is highly vibration absorbent and is excellent in terms of thermal resistance and resistance to loosening.
(FR)
L'invention concerne un corps de structure en forme de filet qui a une structure assemblée à boucle aléatoire tridimensionnelle comprenant des filaments élastomères thermoplastiques continus de 0,1 à 3,0 mm de diamètre de fibre, les filaments élastomères thermoplastiques continus ayant été structurés sous la forme d'un composite à partir d'un élastomère thermoplastique à base de polyester et d'un élastomère thermoplastique à base de polystyrène. Le corps de structure en forme de filet a une contrainte résiduelle de compression à 70 °C de 35 % ou moins, et une résilience de rebondissement de 10 % ou moins. De cette manière, l'invention concerne un corps de structure en forme de filet qui absorbe hautement les vibrations et qui est excellent en termes de résistance thermique et de résistance au desserrage.
(JA)
網状構造体は、繊維径が0.1mm以上3.0mm以下の熱可塑性エラストマー連続線状体からなる三次元ランダムループ接合構造を持ち、熱可塑性エラストマー連続線状体がポリエステル系熱可塑性エラストマーとポリスチレン系熱可塑性エラストマーとで複合構造化されており、70℃圧縮残留歪が35%以下、反発弾性率が10%以下である。これにより、振動吸収性が高くかつ耐熱耐へたり性に優れた網状構造体が提供される。
