Carbon fiber composites (CFCs) offer many advantages for use as structural materials in the aviation, space, marine, automobile, and sports industries. However, some defects like voids, delamination or inhomogeneous fiber distribution that are formed during the fabricating processes of composites. These can impact the mechanical properties of this material. In this study CFC with an EPON 828 matrix, and Toray T700 carbon fibers in a unidirectional weave was subjected to 3D analysis using Robo-Met.3D, an automated serial sectioning system. The objective was to investigate the porosity size and shape distribution (open and closed) and fiber content (and orientation). A representative large volume (of the order of cubic mm) was analyzed at a magnification of 50x, and a spatial resolution of 2.1 microns along X and Y axes.
The resultant microstructure was correlated with results from nondestructive evaluation techniques as well.
