Numerical Simulation Validation and Research on Shield CHaracteristics of Basalt Fiber Woven and Al-Mesh Bumper

Basalt fiber woven as a new type of shielding material has many favorable characteristics while subjected to hypervelocity impact of space debris. A geometrical model for numerical simulation was setup based on the real structure of basalt fiber woven and Al-mesh, and the simulation method is validated through comparison with experiment results. Four types of bumper combination of basalt fiber woven and Al-mesh were presented and the influence of different bumper positions on consumption of kinetic energy of projectile was investigated through numerical simulation. The difference of capability to fragment projectile was also analyzed between basalt fiber woven and Al-mesh.
