摘要：由于复合材料既不是均质的也不是各向同性的，钻孔会产生一些特定的问题，这些问题可能与孔周围区域的后续损坏有关。本章首先讨论了各种钻头的分层理论模型，解释了钻孔引起的分层与推力之间的相关性。接下来考虑分层测量和评估，以及钻孔参数对钻孔引起的分层的影响。生产一致的无分层孔仍然对未来提出了严峻的挑战。
Abstract: Since composites are neither homogeneous nor isotropic, drilling raises specific problems that can be related to subsequent damage in the region around the holes. The chapter first discusses theoretical models of delamination for various drill bits which explain the correlation between drilling-induced delamination and thrust force. Delamination measurement and assessment, and the influence of drilling parameters on drilling-induced delamination are next considered. Producing a consistent delamination-free hole still provides a vigorous challenge for the future.
