Numerical simulation of the impact of an aluminum particle on a composite medium was carried out. Carbon fiber reinforced plastic (CFRP) laminates T300/69 were used as a research object. The behavior of CFRP was analyzed at an impact velocity of 11 km/s and an aluminum particle mass of 1 g. The composite layers were located in planes oriented perpendicular to the direction of reinforcement. The Smoothed-particle hydrodynamics (SPH) method in conjunction with Ansys Autodyn was used for numerical modeling. Since large deformations and fracture of the objects were observed at such high impact velocities, which indicated a violation of the continuity of the material, that makes it incorrect to use of traditional mesh methods. The dependence of the shock wave propagation velocities in CFRP on time was obtained. The minimum thickness of the protective screen made of CFRP was estimated.
Key words: space debris / carbon fiber reinforced plastic / shock waves / Smoothed-particle hydrodynamics method / sound velocity
