| Abstract: |
| The effects of the silica type on the properties of silica/cast PU composites prepared by insitu polymerization were investigated.The test results showed that the dispersibility and stability of hydrophilic silica AEROSIL 200 and hydrophobic silica AEROSIL R972 in poly（ε-caprolactone） （PCL） were better；they could be used to strengthen and toughen silica/cast PU composites and improve the high temperature performance of the composites. |
