项目摘要
The current aerospace industry seeks and asks for new innovative materials to be used for primary aircraft components. Because of their structural performance and light weight, composite materials are now increasingly being used in primary aircraft structures. However, conventional laminated composites only have in-plane oriented fibers making them vulnerable to delamination against impact loads. Therefore, interest for using three-dimensional (3-D) woven composites for aircraft applications is rising. Indeed 3-D woven composites offer higher delamination resistance and damage tolerance because of yarns woven in the through-thickness-direction. However, to support their growing use and applications, a better knowledge of their mechanical properties and behaviour until rupture is required. The applicant's research group has recently begun conducting experimental and numerical studies on the mechanical behavior of a 3D interlock woven composite subjected to impact loading. A preliminary model based on a continuum damage mechanics (CDM) approach has been proposed. It uses three damage variables (in the weft, warp and in-plane shear directions) and take into account inelastic strains in the weft and in-plane shear directions. However, the model currently doesn't take into account coupling between the different damage variables and between the inelastic strains. The main objectives of the research proposal are therefore to improve the constitutive laws and develop reliable and robust numerical tools to predict the mechanical behaviour of 3D woven composites.Laboratory experiments will be conducted to determine coupling effects. Improved damage evolution laws will be proposed as well as a new plasticity development law. Additional impact tests will be performed at different energy levels to validate the model. Next, a realistic representative unit cell will be modelled. A progressive damage will be implemented and the finite-element software Abaqus will be used to test virtually the 3D composite and predict its mechanical behaviour. The results of the virtual tests will allow determining theoretically the parameters and variables used in the constitutive equations, plasticity and damage laws of the macroscopic CDM model. Finally, fatigue tests will be conducted to gain a better understanding of fatigue induced damage and failure modes. The developed numerical tools will allow simulating the structure behavior as a function of the 3D-woven architecture used for the composite reinforcement. The simulations will allow to reduce design cycle and minimize the number of components to be tested. The research results will have the potential to lead to numerous applications in the automotive and aeronautical areas.
当前的航空航天工业寻求并要求新的创新材料用于主要飞机部件。由于其结构性能和重量轻,复合材料现在越来越多地用于飞机的主要结构。然而,传统的层压复合材料仅具有面内取向的纤维,使得它们在冲击载荷下容易分层。因此,使用三维(3-D)编织复合材料的飞机应用的兴趣正在上升。事实上,三维编织复合材料提供了更高的抗分层性和损伤容限,因为纱线编织在整个厚度方向。然而,为了支持其日益增长的使用和应用,需要更好地了解其机械性能和断裂行为。申请人的研究小组最近开始对经受冲击载荷的3D互锁编织复合材料的机械行为进行实验和数值研究。提出了一个基于连续损伤力学(CDM)方法的初步模型。 它使用三个损伤变量(在纬向,经向和面内剪切方向),并考虑在纬向和面内剪切方向的非弹性应变。然而,该模型目前没有考虑不同的损伤变量之间的耦合和非弹性应变之间。因此,研究建议的主要目标是改进本构关系,开发可靠和强大的数值工具来预测三维机织复合材料的力学行为。改进的损伤演化规律将被提出,以及一个新的塑性发展规律。将在不同的能量水平上进行额外的撞击测试,以验证模型。接下来,将对现实的代表性单位单元进行建模。将实施渐进破坏,并使用有限元软件Abaqus对3D复合材料进行虚拟测试,并预测其机械性能。虚拟试验的结果将允许从理论上确定用于宏观CDM模型的本构方程、塑性和损伤定律中的参数和变量。最后,将进行疲劳试验,以更好地了解疲劳引起的损伤和失效模式。开发的数值工具将允许模拟作为用于复合材料加固的3D编织结构的功能的结构行为。模拟将允许缩短设计周期,并最大限度地减少要测试的组件数量。研究结果将有可能导致汽车和航空领域的众多应用。
