The Development of a Water-Soluble Core Material for Manufacturing Hollow Composite Sections
This paper presents the development of a low cost water-soluble core material, which is suitable for producing hollow composite structures via high pressure moulding processes, such as compression moulding and resin transfer moulding. The composition of the core has been optimised to provide rapid dissolution and mechanical properties that exceed those of commercially available cores. Compressive strengths of up to 57 MPa and flexural strengths of up to 10 MPa can be achieved, and the core can be used at high composite processing temperatures (120°C). A practical example is presented, using the removable core to produce representative hollow sections typically found in the automotive industry.
