Recently, polymeric nanofiber veils have gained lot of interest for various industrial and research applications. Embedding polymeric veils has proven to be one of the most effective ways to prevent delamination caused by the poor out-of-plane properties of composite laminates. The polymeric veils are introduced between plies of a composite laminate, and their targeted effects on delamination initiation and propagation have been widely studied. This paper presents an overview of the application of nanofiber polymeric veils as toughening interleaves in fiber-reinforced composite laminates. It presents a systematic comparative analysis and summary of attainable fracture toughness improvements based on electrospun veil materials. Both Mode I and Mode II tests are covered. Various popular veil materials and their modifications are considered. The toughening mechanisms introduced by polymeric veils are identified, listed, and analyzed. The numerical modeling of failure in Mode I and Mode II delamination is also discussed. This analytical review can be used as guidance for veil material selection, for estimation of the achievable toughening effect, for understanding the toughening mechanism introduced by veils, and for the numerical modeling of delamination.
近年来，聚合物纳米纤维面纱在各种工业和研究应用中引起了广泛关注。事实证明，嵌入聚合物面纱是防止复合层压板因面外性能不佳而分层的最有效方法之一。聚合物面纱被引入到复合层压板的层间，并且它们对分层起始和扩展的靶向作用已得到广泛研究。本文概述了纳米纤维聚合物面纱作为纤维增强复合层压板增韧夹层的应用。它基于电纺面纱材料对可实现的断裂韧性提高进行了系统的对比分析和总结。涵盖了I型和II型测试。考虑了各种常见的面纱材料及其改性。确定、列出并分析了聚合物面纱引入的增韧机制。还讨论了I型和II型分层破坏的数值模拟。这一分析综述可作为面纱材料选择的指导，用于估计可实现的增韧效果，理解面纱引入的增韧机制，以及用于分层的数值模拟。
