    • A flexible, impact-resistant laminate (1) comprises a first layer of a flexible material (2) and a second, impact-resistant layer (4). The impact-resistant layer (4) comprises an impact-resistant material (6) interposed between regions of a closed-cell foam (5) that is bonded to the first layer (2) such that preferably the impact-resistant material (6) substantially fills the spaces defined between the regions of the closed-cell foam (5). The impact- resistance material (6) preferably comprises an elastomeric material or, if a third layer (3) of a flexible material is bonded to the closed-cell foam (5) on the other side of the laminate to the first layer of material, a packing comprised of a packing comprised of tightly packed beads or particles (7). A method of manufacturing such a laminate comprises the steps of providing a first, flexible layer (19) of material; bonding regions of a closed-cell foam (8, 18) to an inner side of the first layer (19); and introducing an impact- resistant material (6) into spaces (9) defined between the regions of the closed-cell foam (8, 18) to form a second, impact resistant layer. An inner side of the third layer (22) of a flexible material may be bonded to the closed- cell foam (8, 18) on the other side of the laminate to the first layer (19) of material.
    • 柔性耐冲击层压板(1)包括第一层柔性材料(2)和第二耐冲击层(4)。 抗冲击层(4)包括插入在与第一层(2)接合的闭孔泡沫体(5)的区域之间的抗冲击材料(6),使得优选的耐冲击材料(6) 基本上填充限定在闭孔泡沫(5)的区域之间的空间。 耐冲击材料(6)优选地包括弹性体材料,或者如果柔性材料的第三层(3)与层压体的另一侧上的闭孔泡沫(5)结合到第一材料层 ,包括由紧密堆积的珠粒或颗粒(7)组成的填料的填料。 制造这种层压板的方法包括以下步骤:提供材料的第一柔性层(19); 闭孔泡沫(8,18)的粘合区域到第一层(19)的内侧; 以及将抗冲击材料(6)引入限定在闭孔泡沫(8,18)的区域之间的空间(9)中以形成第二耐冲击层。 柔性材料的第三层(22)的内侧可以在层压体的另一侧与材料的第一层(19)结合到闭孔泡沫(8,18)上。
