AB  - Three-dimensional insights into the microstructure of composite materials are vital for enhancing their perfor-mance under operational conditions. Phase-sensitive methods can offer supplementary data, especially for ma-terials with low absorption, compared to standard absorption-based techniques. This work presents thecorrelative X-ray imaging and computed tomography results of polymer composites reinforced with glass fibersusing an inverted Hartmann mask. This method identified areas with enhanced refraction and scattering due toglass fibers and discriminated signals based on their orientation, offering an advantage in evaluating anisotropicmaterials. The simplicity of the setup, adding the inverted Hartmann mask, makes integration feasible in com-mercial CT scanners and existing radiography laboratories, enabling simultaneous phase, scattering, and ab-sorption information extraction. Our approach, which combines refraction and scattering with absorptionsignals, exposes intricate structures beyond the usual spatial resolution threshold. Despite the distinct absorptioncoefficients of air, polymer-based, and glass fibers, the inverted Hartmann mask is crucial for examining similarabsorption composites and low-absorbing materials. This research offers profound insights into the micro-structures of fiber-reinforced polymer composites, laying the groundwork for studies of nanostructured func-tional composite materials
