... of withstanding the high temperatures and pressures. In a typical bagging operation ( Fig. 6.3 ), the materials required include high-temperature polyimide bagging material, glass bleeder cloth, and silicone bag sealant. The polyimide bagging materials (for example, Kapton or Upilex) are more brittle and harder...
