Enhanced damping characteristics of carbon fiber reinforced polymer–based shear thickening fluid hybrid composite structures - Jaehyeong Lim, Sang-Woo Kim
Lightweight carbon fiber reinforced polymer composite structures with high stiffness are at risk of resonant vibration. Our study proposes a methodology to reduce this risk by passively improving the damping ratio of carbon fiber reinforced polymer composite structures. We developed shear thickening fluid hybrid composite structures by applying polyimide tubes filled with shear thickening fluid having rheological properties into a composite laminate. In order to verify the proposed methodology, carbon fiber reinforced polymer–based shear thickening fluid hybrid composite beams were fabricated, and modal tests were subsequently performed to investigate their dynamic characteristics.
