Evaluation of a New Method for Forming Bodies that Achieves Fiber Filling Improvement and Void Reduction [Technical Document]

Visual inspection and confirmation of the internal condition of the molded body using X-ray CT were conducted! The quality of the three-dimensional molded body produced by the new method was evaluated.

This document presents a technical report on three-dimensional shaped parts with uneven surfaces formed using conventional and new methods. It includes non-destructive testing through visual inspection and X-ray CT to verify the technical superiority of the new method, along with the results. The visual inspection results suggest that the parts produced by the conventional method exhibited burrs at the corners, indicating instability in the positioning of the reinforcing fibers compared to those produced by the new method. The new method's molded products were recognized as superior in terms of quality. Additionally, upon examining the X-ray CT images, it was found that the parts made using the conventional method showed an increase in resin-rich areas due to the movement of reinforcing fibers, as well as intermittent air layers (voids) at the boundary layer between the matrix resin and the reinforcing fibers.
