ISO 18352:2009规定了一种测定多向聚合物基复合材料层压板残余压缩强度的方法，该层压板在施加面内压缩载荷之前因冲击而受损。 本试验方法适用于连续纤维增强聚合物基复合材料。该方法的应用仅限于由单向预浸带/织物或机织物制成的具有多向增强体的纤维增强塑料层压板。 当用于确定受冲击板的残余压缩强度时，该试验方法称为冲击后压缩（CAI）试验。它可用于获取材料规格、材料评估、研发或复合数据库构建的数据。

ISO 18352:2009 specifies a method for determining the residual compression strength of multidirectional polymer matrix composite laminate plates that have been damaged by impact prior to the application of in-plane compressive loading. The test method is suitable for continuous-fibre-reinforced polymer matrix composites. Application of the method is limited to fibre-reinforced plastic laminates with multidirectional reinforcements manufactured from unidirectional prepreg tapes/fabrics or woven fabrics. The test method is referred to as the compression-after-impact (CAI) test when used to determine the residual compression strength of an impacted plate. It can be used to obtain data for material specification, material evaluation, research and development, or construction of a composite database.
