Abstract:
Polymer composites represent very useful materials due to a possibility to design various properties with the combination of ceramic reinforcements in the shape of particles and fibers. Thanks to this, composites are being applied in every industry, from commercial products to high performance materials for aircrafts. Microelectronic devices contain polymers and composites as insulators and adhesives, mostly epoxy-based. In order to improve their mechanical properties, such as modulus of elasticity of impact resistance, and endurance, glass fibers are incorporated as reinforcement. For the design of a composite with desired mechanical properties and long-life, thorough knowledge of microstructural changes and fiber-matrix interface is required. Microstructural analysis can also provide insight in reinforcement shape that can enable connection with the physical properties. Fractal nature analysis represents mathematical tool that can be used for the shape and size reconstruction, ensuring prediction of different properties, which is valuable for the future materials processing. In this paper, field emission scanning electron microscopy (FESEM) images were used for fibers microstructure fractal analysis. Reconstruction of fiber shape was obtained successfully, opening the door for the application of fractal analysis shape reconstruction application on other materials, with the future focus on nanomaterials used in microelectronic devices
