| Abstract Scope |
Due to design flexibility, tailored material properties, and cost efficiency, additive manufacturing (AM) of continuous fibrous composites has emerged as a revolutionary technology for composite manufacturing. It has demonstrated the potential to replace expensive and labor-intensive manufacturing processes such as autoclave molding. However, challenges persist in achieving reliability, consistency, and quality in AM composites, which is crucial to aerospace applications. The common concern is that the strengths of the 3D-printed composites are notably lower and scattered compared to conventionally manufactured composites and metals. Therefore, there is a pressing need to quantify the statistical strength distribution of AM composites. This research demonstrates a high-throughput testing method to efficiently measure the strength distribution of the material especially for the strength data at the lower tail region of the probability distribution. The concept involves subjecting a group of samples to the same load, enabling them to fail one by one in ascending order. The strength of each sample can then be obtained from the load-displacement curve. |
