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:
