X-ray tomography 3D image dataset of natural fibre reinforced polypropylene
<p>Natural fibre composites have potential sustainability benefits over traditional composites, but their irregular shapes and mechanical properties require more thorough examination compared to glass or carbon fibre composites. 3D X-ray imaging allows for non-destructive examination of the structure and shape. The dataset includes 3D images obtained using micro X-ray computed tomography of natural fibre composites. The images provide valuable insights into the material's characteristics. Since there is limited open-access 3D image data on natural fibre composites, this dataset lays the groundwork for future image analysis and numerical modelling.</p>
