Moulding Hollow Carbon Fibre Parts Using a Low-Melt Metal Mandrel

Product links ► Further information ▼ In this composites training video, we demonstrate how low-melting 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 melt-out the metal core, leaving the hollow composite structure. For full details on the products used, as well as a step-by-step 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
