Microstructural analysis is of particular importance to understand the mechanical behaviour of short fiber reinforced composites. A non‐destructive, high resolution X‐ray microtomography (Micro‐CT) technique was used to determine length, width and volume distributions of the wood and hemp fibers in polypropylene (PP) based composites. Results show that the use of the MAH‐PP coupling agent decreased the fiber breakage in the composite considerably. Noticeable small width distribution and higher aspect ratio were obtained for the carded and enzyme separated hemp fibers.
