Abstract

Auxetic composite laminates, i.e. laminates with a NPR (Negative Poisson’s Ratio), are regarded as a promising solution to combat LVI (Low-velocity impact) delamination BVID (Barely visible internal damage) and ensuing property degradation, a cause for concern in aerospace components, mainly inflicted by fortuitous accidents during handling operations. In order to potentiate the auxetic effect through the minimization of the Poisson’s ratio, a thorough analysis of material properties and stacking sequences is required, as only a restricted domain of combinations can generate the desired effect, either in an IP (In-plane) or TTT (Through-the-thickness) configuration. This paper focuses on a MATLAB program developed for IP and TTT auxetic laminate design, based on the CLT (Classical Lamination Theory). Cases studies on NPR domain definition of C/E (Carbon/epoxy), G/E (Glass/epoxy) and hybrid C-G/E (Carbon-Glass/epoxy) laminates are presented. Moreover, the influence of fibre volume fraction on C/E and G/E laminates is analysed.

平面内和厚度内辅助复合材料层压板的分析设计
辅助复合材料层压板,即具有负泊松比的层压板,被认为是应对低速冲击(LVI)分层 BVID(几乎看不见的内部损伤)和随之而来的性能下降的一种有前途的解决方案。为了通过最小化泊松比来增强辅助效应,需要对材料特性和堆叠顺序进行全面分析,因为只有有限的组合才能在 IP(面内)或 TTT(穿透厚度)配置中产生所需的效果。本文重点介绍基于 CLT(经典层压理论)开发的用于 IP 和 TTT 辅助层压板设计的 MATLAB 程序。文中介绍了 C/E(碳/环氧)、G/E(玻璃/环氧)和混合 C-G/E(碳-玻璃/环氧)层压板的 NPR 域定义案例研究。此外,还分析了纤维体积分数对 C/E 和 G/E 层压板的影响。
