The role of matrix boundary in the microstructure of unidirectional composities
conference paper
Finding new ways to evaluate the microstructural characteristics and their effect on macroscopic properties such as permeability and mechanical performance is of increasing interest for fibre reinforced polymer composites. The three-dimensional variability of microstructural features is not fully understood and its effect on macroscale properties is not well established, and so far mostly analysed at a phenomenological level. In order to achieve a more complete definition of the unidirectional composites domain, an understanding of matrix-based features and their interrelation with fibre architecture descriptors is needed. We introduced in recent work a method based on X-ray Computed Tomography for the quantification of fibre-architecture descriptors at an increasing level of complexity. To expand the methodology, this work accounts for matrix-based phenomena such as tape boundary variability and distribution of voids. (C) 2022 Gomarasca et al.
