概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
I use the micro X-ray focus CT scan to analyse the internal structure of my composite material. The sample had been biodegraded in compost for several weeks, and I wanted to test if X-rays could be used to visualize the internal structure before and after biodegradation.
実験 / Experimental
I used the micro X-ray focus CT scan on my samples. X-ray was used to get 3D-images of the internal structure of non-biodegraded and partially biodegraded samples.
結果と考察 / Results and Discussion
Unfortunately, it was difficult to observe the internal structure clearly. Cracks were formed inside the structure, but they were difficult to visualize clearly. In addition, the composite material was not homogenous, so it was difficult to distinguish inhomogeneities due to the fabrication method, from the cracks/damages which were due to biodegradation. Consequently, for this material, observations of the cross-section using microscope may be a better method for visualizing structural changes.
