The feature evaluation, property control, and social implementation of advanced composite materials play a crucial role in addressing environmental, energy, and resource issues, contributing to the realization of GX and SDGs in our society. Discontinuous CFRP is recognized as an inevitable solution for complex-shape molding, high-cycle molding, and CF-recycle applications. However, the fabrication process of discontinuous CFRP results in an extremely complicated internal fiber geometry, significantly reducing prediction accuracy with traditional mechanical models. To establish a practical methodology and facilitate the social implementation of this material, we conduct comprehensive evaluations of the molding process, internal geometry, and mechanical properties.

High-performance discontinuous CFRP demonstrate strong property-variation. The evaluation and control of this property-variation are unneglectable for structural applications. Our emphasis lies in assessing material properties and their variations through the application of statistical methods, such as the Monte Carlo model. This evaluation takes into account the comprehensive aspects of the molding process, internal geometry, and mechanical properties.

To realize a rapid and cost-effective social implementation, we engage in not only analyzing theories and techniques to evaluate and control detailed mechanical properties but also synthesizing, approximating, and systematizing these theories and techniques to align with the overall vision of the application target.
