Design and Manufacturing of High Performance Structural Components by Resin Transfer Moulding

The ability to reduce the manufacturing and operating cost of high performance structural components and vehicles governs the competitiveness in the market. The use of RTM technologies in Aerospace applications gives added potential in recent days due to the combined benefit of weight — cost reduction. Complicated components could be easily manufactured by one injection, provided that the mould has been well designed and the positioning of gate ports accurately defined by flow simulation. In the present work a sequenced methodology was established for the development of an aircraft structural stiffened skin. A mould with inserted heating elements and preformed reinforcements were used for the manufacturing of component The experimental Investigation lead to various techniques for eliminating lack of wetting and improving the quality of final product.
