The mechanical properties of sandwich panels with a polyurethane core and fiberglass face layers produced by a continuous lamination process have been studied. Tensile, compression and shear tests were performed on isolated face layer materials. Using a nonlinear finite-element model, the mechanical behavior of the sandwich panels in flatwise compression, edgewise compression, and bending was simulated, and a good agreement with experiments was found to exist.

玻璃纤维/聚氨酯夹芯板的压缩和弯曲行为：实验和数值研究

已经研究了通过连续层压工艺生产的具有聚氨酯芯和玻璃纤维面层的夹层板的机械性能。对隔离的面层材料进行了拉伸、压缩和剪切测试。使用非线性有限元模型，对夹层板在平面压缩、边缘压缩和弯曲中的力学行为进行了模拟，发现与实验存在良好的一致性。
