Composites Collaboration Demonstrates Low-Cost Manufacturing Technology

Dépèche transmise le 15 juin 2009 par PRNewswire

PARIS AIR SHOW - LE BOURGET, France, June 15 /PRNewswire/ -- Bristol Aerospace, a division of Magellan Aerospace, in collaboration with Boeing Research & Technology and the Composites Innovation Centre in Winnipeg, MB, completed a research program to investigate out-of-autoclave processing for potential use in composite aircraft components. These composites can be cured in an oven under a vacuum bag with no additional external pressure applied. Next generation out-of-autoclave composites that offer performance comparable to traditional materials are now being developed by suppliers. The goal of the project was to demonstrate that an out-of-autoclave process could be used to fabricate components that would satisfy the strict requirements for aerospace grade parts.

High performance composite structures for aircrafts are typically manufactured using an autoclave, to cure components under the application of heat and pressure. This approach involves significant production costs from expenses required to purchase, operate, and maintain the necessary equipment and tooling. Out-of-autoclave processing is gaining increased interest in the aerospace industry as a potential opportunity for cost savings.

The study focused on potential applications for one commercially available material. Manufacturing trials were conducted at Bristol's Winnipeg plant in its state-of-the-art Composites Manufacturing Centre. All three partners were involved in inspection to assess the quality of the final test articles. "Our first attempt to produce a generic part using an out-of-autoclave manufacturing process proved to be a great success," said Shawna Boyko, Project Manager and Composites Engineering Technical Specialist at Bristol. "Inspection and coupon testing of the demonstration article showed good compaction and virtually no voids, exceeding typical quality requirements by a fair margin."

Based on positive results from the current program, Bristol intends to continue exploring alternative manufacturing methods for composite structures. Vice President and General Manager Don Boitson stated "Innovative manufacturing technologies such as out-of-autoclave processing presents an opportunity for us to reduce production costs while maintaining a high level of quality, increasing the value we provide to our customers."

The success achieved in this project encourages further collaborative research to include additional composite formulations and methodologies to ultimately match the properties of autoclave cured structures with the lower costs of out-of-autoclave curing.
