    • The present invention is directed to composite structures by thermoplastically shaping an assembly of at least two flat thermoplastically formable plastic materials placed in layers one above the other and optionally at least one upper, lower and/or intermediate layer containing a reinforcing or filler material under such conditions of temperature and pressure that shaping is accompanied by intimate union of the individual layers of the assembly, characterized in that at least one of the flat plastic materials is based on a polyisocyanate polyaddition product having a density of at least 0.8 g/cm.sup.3 which has been prepared by the reaction of(a) aromatic polyisocyanates,(b) compounds having a molecular weight of 1800 to about 12000 and containing a statistical average of at least 2.5 isocyanate-reactive groups, optionally(c) diamines in the molecular weight range of 108 to 400 containing two primary and/or secondary aromatically bound amino groups, and optionally(d) (cyclo)alkanepolyols and/or (cyclo)alkanepolyamines in the molecular weight range of 60 to 1799 optionally containing ether groups,by a single stage or multi-stage process at an isocyanate index of 60 to 140, wherein at least one of components (c) or (d) is used in a quantity such that the total quantity of components (c) and (d) is at least 5% by weight, based on the weight of component (b).
    • 本发明涉及复合结构,其通过将至少两个平坦的可塑成形塑料材料的组件热塑成形,一个层叠在另一层之上,以及任选地至少一层含有增强或填充材料的上,下和/或中间层 温度和压力的条件是成形伴随着组件的各个层的紧密结合,其特征在于,所述扁平塑料材料中的至少一种基于密度为至少0.8g / cm 3的多异氰酸酯加聚产物,其具有 通过(a)芳族多异氰酸酯的反应制备,(b)分子量为1800至约12000的化合物,并且含有至少2.5个异氰酸酯反应性基团的统计平均值,任选(c)分子量范围内的二胺 108至400,其含有两个伯和/或二次芳香结合的氨基,以及任选的(d)(环)烷撑多糖 通过在异氰酸酯指数为60至140的单级或多级方法,任选地含有醚基的分子量范围为60至1799的(环)链烷多胺和/或(环)链烷多胺,其中至少一种组分(c)或 (d)的使用量使得组分(c)和(d)的总量基于组分(b)的重量为至少5重量%。
