An experimental method to measure the reduced stiffness of the fatigue loaded polymer concrete was developed. Fatigue testing of the concrete was performed by applying a periodic load in bending tests. To investigate the reduction of stiffness due to fatigue damage, the frequency dependent variations of the dynamic stiffness and loss factor of the polymer concretes (a mixture of epoxy resin, carbon...
In this paper, the mechanical/dynamic property of the carbon fiber reinforced polymer concrete (CFRPC) was investigated to reduce the vibration/noise problems on rail slab. The CFRPC was fabricated with the different weight fraction of carbon fiber and different fiber length. The oxygen plasma treatment was performed to enhance the adhesion between the carbon fiber and epoxy resin. The surface of...
