Thermosetting resins are used in various performance applications. Especially, the epoxy resins have good dimensional stability, good stiffness, specific strength, chemical resistance, anti-corrosion, moisture resistance, and low shrinkage. However, the main disadvantages of epoxy resins are low toughness and poor resistance to crack propagation due to its brittleness. Epoxy resins need to be toughened with a second component to improve the mechanical properties. One of the successful methods is rubber toughening epoxy resins. The advantage of using the rubber toughening epoxy resins is that the fracture toughness increases without a reduction in other mechanical properties such as tensile strength and flexural strength. In this study, we investigated the properties of epoxy resins/natural rubber composites using X-ray diffraction analysis (XRD), probe tack test, thermo-gravimetric analysis (TGA), scanning electron microscope (SEM), and flexural test. |
