Moulding Hollow Carbon Fibre Parts Using a Low Melt Metal Mandrel

Product links Further information In this composites training video, we demonstrate how lowmelting point metal alloys can be used as sacrificial cores, mandrels when manufacturing hollow composite structures. The process can be used to produce complex hollow structures, such as tubes or frame components by laminating prepreg carbon fibre around a cast metal mandrel, which is then cured at elevated temperature before the temperature is increased further to meltout the metal core, leaving the hollow composite structure. For full details on the products used, as well as a stepbystep breakdown of the process, see the project page on the Easy Composites website: Full Project Details UK and World EU 00:00 Introduction 02:23 Maki
