  • Methods for forming composite tubing having tapered ends
    Patent number: 5192384
    Abstract: Reinforced composite tubes having integral tapered ends are formed on mandrels which are tapered at each end. Reinforcement fabric is first conformed to the mandrel with at least one end of the fabric structure retaining an opening therein. The mandrel is disassembled and removed through the opening, and a matrix cured within the fabric to produce the desired composite. Usually, the fabric structure will be cured in an external mold with an inflatable mandrel inserted through the opening applying internal pressure.
