High-Tc superconducting YBa2Cu3O $_{7\mbox{-}\delta}$ phase was produced by a solid state reaction method. A series of YBa2Cu3O $_{7\mbox{-}\delta}$/polymer composites were fabricated. The structure, physical property, levitation and mechanical strength of composites were carried out. The Meissner effects associated with the 91K superconducting transition were found to be roughly preserved in the composites. Elastic experiments are carried out by applying a uniaxial pressure. Young's modulus of compression and compressibility was calculated. It increases with the volume fraction $\Phi$ s of superconductor. Poisson's coefficient was determined. The role of contacts between component is discussed.
