碳纤维增强塑料（CFRP）具有高阻尼能力和高强度特性的新材料已经得到研究。这些材料在本文中称为 CFRP/阻尼材料层压板。这里研究的 CFRP/阻尼材料层压板由单向碳/环氧预浸料片和用作中间层的聚乙烯基阻尼材料片组成。悬臂梁测试揭示了这些层压板的高阻尼特性。这些复合材料的损耗因子值是传统 CFRP 的 10 至 100 倍。除了两个样本之外，这些值可以通过使用约束层阻尼理论来预测。
New materials, that possess high damping capabilities and high strength properties, have been studied in carbon fiber reinforced plastics (CFRP). These materials are referred to in this article as CFRP/damping-material laminates. The CFRP/damping-material laminates investigated here are composed of a unidirectional carbon/epoxy prepreg sheet and a polyethylene based damping material sheet used as an interleaf. Cantilever beam tests revealed the high damping properties of these laminates. Loss factor values for these composites are 10 to 100 times as large as that for conventional CFRP. These values could be predicted by using the constrained layer damping theory, except for two specimens.
