Abstract: Composites not only afford the designer the luxury of increased specific strength and stiffness and durability over metals but also offer the potential of greater manufacturing flexibility in making large complex parts and reducing assembly through parts integration. However, composite parts rarely form the entire structure or system. Hence, integration of the composite members with the rest of the system is a critical part of the design process. In this paper, we briefly review the incorporation of metal inserts or attachments in composite compartments. The advantages and limitations of using injection moulding, compression molding, filament winding, and resin transfer moulding (RTM) as processes to encapsulate the insert/attachment are reviewed. Particular attention is given to the incorporation of metal inserts in composites using resin transfer moulding (RTM), because the process offers the advantages of local tailorability and encapsulation through textile performing processes. Issues of interest and the critical needs of industry in the further development of this processing technology are addressed.

Keywords: adhesion; composites; metal inserts; resin transfer moulding; structural assembly; injection moulding; compression moulding; filament winding.
