Abstract: A composite body is provided that includes a rigid polyurethane foam shell and an elastomeric polyurethane layer disposed over the rigid polyurethane foam shell. The rigid polyurethane foam shell defines a cavity within the composite body. The rigid polyurethane foam shell has a closed cell content of at least 70% and comprises the reaction product of a first isocyanate component and a first isocyanate-reactive component in the presence of a blowing agent. The elastomeric polyurethane layer is disposed over the polyurethane foam shell. The elastomeric polyurethane layer comprises the reaction product of a second isocyanate component and a second isocyanate-reactive component. A method of forming the composite body includes the step of molding the rigid polyurethane foam shell, demolding the rigid polyurethane foam shell from the mold, and applying an elastomeric polyurethane composition upon the rigid polyurethane foam shell after demolding to form the elastomeric polyurethane layer.

Abstract translation: 提供了一种复合体，其包括刚性聚氨酯泡沫壳和设置在刚性聚氨酯泡沫壳上方的弹性体聚氨酯层。 刚性聚氨酯泡沫壳体在复合体内限定了一个空腔。 刚性聚氨酯泡沫壳体的闭孔含量至少为70％，并且在发泡剂存在下包含第一异氰酸酯组分和第一异氰酸酯反应性组分的反应产物。 弹性聚氨酯层设置在聚氨酯泡沫外壳上。 弹性聚氨酯层包括第二异氰酸酯组分和第二异氰酸酯反应性组分的反应产物。 形成复合体的方法包括：模制硬质聚氨酯泡沫壳体，将硬质聚氨酯泡沫壳体从模具脱模，以及将脱模后的弹性体聚氨酯组合物施加到硬质聚氨酯泡沫壳体上以形成弹性体聚氨酯层的步骤。
