Patents Assigned to Comtek Advanced Structures Limited
  • Patent number: 7824165
    Abstract: Among other things, there is disclosed a system for curing a resin in a composite structure having one or more interconnected cure volumes, the cure volumes having one or more heatable surface zones. The system comprises a mould comprising a mould base portion adapted to support the composite structure and a mould closure portion adapted to overlie the mould base portion in sealable relation to define a mould chamber containing the composite structure within. The system further comprises a plurality of heating units each selectively positionable about the mould. The heating units transmit heat to the mould by radiation, and the mould heats the one or more surface zones of the cure volumes.

  • Patent number: 7758800
    Abstract: Among other things, the present invention provides a system and method for improved infusion of a fiber containing preform with a resin. The system comprises a mould base portion adapted to support the preform and a mould closure portion adapted to overlie the mould base portion in sealable relation to define a mould chamber containing the preform. One or more sensors are attached to the mould base portion and/or to the mould closure portion for monitoring flow characteristics of the resin within the mould chamber. A control means responsive to the sensing means is operatively connected to a resin pump and to a vacuum pump for varying the flow of resin within the mould chamber by varying either or both of the volumetric flow rate of the resin and the level of vacuum within the mould chamber to control infusion of the preform.
