    Abstract: A pliable bentwood laminate with an intermediate layer (2), in particular forming a central layer, having a first and a second surface side, wherein on the first surface side a first outer timber layer (3) is provided, and on the second surface side a second outer timber layer (4) is provided, wherein the distance between the outer surface of the first outer timber layer (3) and the outer surface of the second outer timber layer (4) amounts to at least 8 mm, wherein the first and second outer timber layers (3, 4) are formed from peeled balsawood veneer, and wherein the density of the first and second outer timber layers (3, 4), with a residual moisture content of 12% by weight with respect to the timber mass, amounts to less than 200 kg/m3, and wherein the first and second outer timber layers (3,4) have peeling cracks (5) on one surface side, wherein, the first and second outer timber layers (3, 4) are arranged such that the surface side having the peeling cracks (5) is facing away from the intermediate layer (2) and wherein, the bentwood laminate can be curved and/or is curved with an inner bending radius from a range of values of between 100 mm and 250 mm, and wherein, the intermediate layer is designed as a directional timber layer, and wherein, a neutral fibre of the bentwood laminate runs in the intermediate layer, and in that, timber fibres of the directional intermediate layer run at right-angles to the longitudinal extent of the peeling cracks of the first and second outer timber layers (3, 4).

    Abstract translation: 一种具有中间层(2)的柔韧的弯曲木材层压物,特别是形成具有第一和第二表面侧的中心层,其中在第一表面侧上设置有第一外层木材层(3),并且在第二表面 提供第二外木层(4),其中第一外木层(3)的外表面和第二外木层(4)的外表面之间的距离至少为8mm,其中, 第一和第二外部木材层(3,4)由剥离的果木木皮单板形成,并且其中第一和第二外部木材层(3,4)的密度相对于第一和第二外部木材层的剩余水分含量为12重量% 木材质量小于200kg / m 3,并且其中第一和第二外部木材层(3,4)在一个表面侧具有剥离裂纹(5),其中,第一和第二外部木材层(3,4) )被布置成使得具有剥离裂纹(5)的表面侧面向外 中间层(2),其中,弯曲木材层压板可以弯曲和/或弯曲,内弯曲半径从100mm至250mm的值的范围,并且其中,中间层被设计为定向 木材层,并且其中,弯曲木材层压材料的中性纤维在中间层中延伸,并且由此,定向中间层的木材纤维与第一和第二外部木材的剥离裂纹的纵向范围成直角地延伸 层(3,4)。
