The non-uniform distribution of additives can have a significant impact on the mechanical, thermal, and chemical properties of the composite. Uneven distribution can result in variations in material strength, stiffness, and resistance upon application of outside force. Furthermore, in Figure (f), process produces SEM is a powerful technique for analyzing the microstructure of composite materials. Its exposure to the curing process produces microstructural defects in a polymer matrix, such as voids, cracks, inhomogeneities, and other imperfections. These defects can weaken the material and reduce its overall performance. SEM images can reveal how MEPECO interacts with these defects. The coverage of microstructural defects by MEPECO can depend on their chemical properties, viscosities, and processing conditions. As the SEM images show, the MEPECO successfully penetrates these defects and forms a protective barrier. More so, inVE_5% MEPECO, where its effective coverage of microstructural defects improved the mechanical properties of the composite material.
