A sports board comprises: an upper board and a lower board disposed to be spaced apart from each other; and a core attached between the upper board and the lower board. The core comprises an auxetic buffer part having a structure with a negative Poisson's ratio. By comprising the core comprising the auxetic buffer part, the sports board can reflect a structural characteristic in the core corresponding to the entire board or a part of the board, so as to meet a specific numerical range of required physical characteristics.

    La présente invention concerne une planche de sport qui comprend : une planche supérieure et une planche inférieure disposées de façon à être espacées l'une de l'autre ; et une partie centrale fixée entre la planche supérieure et la planche inférieure. La partie centrale comprend une partie tampon auxétique ayant une structure dotée d'un nombre de Poisson négatif. En comprenant la partie centrale qui comprend la partie tampon auxétique, la planche de sport peut refléter une caractéristique structurale dans la partie centrale correspondant à la planche entière ou à une partie de la planche, de façon à satisfaire à une plage numérique spécifique de caractéristiques physiques requises.

    스포츠용 보드는 상하로 이격되어 배치되는 상판 및 하판과, 상판과 하판 사이에 부착되는 코어를 포함한다. 코어는 음의 푸아송비의 구조로 이루어진 오그제틱 완충부를 포함한다. 스포츠용 보드는 오그제틱 완충부를 구비하는 코어를 포함하여, 요구되는 물리적 특성에 대한 구체적인 수치 범위를 만족하도록, 보드 전체 또는 일부에 대응하는 코어에 구조적 특징을 반영할 수 있다.
