Abstract

一种用于风力发电机叶片的材料芯(100)，包括：芯体(101)；第一凹槽(102)，其从芯体(101)的第一侧(104)沿第一方向(106)延伸到芯体(101)中的深度d1中；以及第二凹槽(103)，其从芯体(101)背向第一侧(104)的第二侧(105)沿与第一方向(106)相反的方向延伸到芯体(101)中的深度d2，其中第二凹槽(103)与第一凹槽(102)平行；以及其中：d2＝t-d1+x，1mm≤x＜d1，其中t是芯体(101)的厚度，并且其中第一凹槽与第二凹槽之间的距离是o，其中：1mm≤o≤5mm。可以增强芯的悬垂性，同时降低所制造的芯的特性对制造变化的敏感性，同时可以实现诸如达到灌注板的最佳强度和刚度的附加优点。
