【 摘 要 】

One of the most important factors to determine the mechanical properties of a fibre composite material is the orientation of the fibres in the matrix. Their orientation might differ in distinct parts of the structural element as dependent on the casting techniques and mould materials. This paper presents an algorithm to retrieve information on a single fibre’s orientation out of SFRC samples scanned through a µCT scanner. The software implemented with the algorithm includes a data filtering component to remove the noise from the data sets and prepare them correctly for analysis. Due to its short computational times and its almost complete lack of need for external user intervention, the software is able to process and analyse large batches of data in short periods by providing results in a variety of visual and numerical formats.
