摘要

单层缎纹编织物的主要纤维方向不同，取决于是上侧还是下侧。这会影响层压板的热变形和主曲率方向。因此，我们为单层缎纹编织物复合材料提出了一个两层交叉层压模型，以考虑主导纤维方向。为了验证我们的模型，我们推导出了传统模型和建议模型在热载荷下的非对称角层压板的分析解。通过将分析解与单向编织物和缎纹编织物复合材料的实验结果进行比较，我们证实所提出的模型能准确预测主曲率方向。

A two-layered cross-ply laminate model for a single-ply satin woven fabric composite under thermal loads

The dominant fiber direction of a single-ply satin woven fabric is different depending on whether it is the upper or lower side. This affects the thermal distortion of laminates and principal curvature directions. Therefore, we propose a two-layered cross-ply laminate model for a single-ply satin woven fabric composite to consider the dominant fiber directions. To verify our model, we derive analytical solutions of antisymmetric angle-ply laminates under thermal loads for the conventional and proposed models. By comparing the analytical solutions with experimental results of unidirectional and satin woven fabric composites, we confirm that the proposed model accurately predicts the principal curvature direction.

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
