Investigation on the Dynamic Mechanical Properties of Self-Healing Glass Fibre Reinforced Plastics

J. Lilly Mercy, S. Prakash


Self-healing polymeric materials developed in the last decade is one of the marvels in the field of material science and polymer chemistry. Self-healing Glass Fibre Reinforced Plastics (GFRP) was fabricated with the microcapsule based self-healing system which can be triggered by the catalyst, when the capsule breaks open releasing the healing agent, during crack formation. The dynamic mechanical properties of the composite were assessed to find its dependence on temperature, stress and frequency and to report the changes in stiffness and damping. The storage modulus, loss modulus and damping factor were investigated for various frequencies and temperature and discussed.
