DESCRIPTION
MULTIPLAST uses the vacuum infusion process to manufacture composite structures in monolithic or foam sandwich form.
This process consists of:
- Position the dry fibres (carbon or glass, etc.) as well as the inserts and core foams in the mould or on a marble slab.
- Set up a vacuum sealing system with suitable film and consumables according to an infusion strategy tailored to each individual case.
- Create controlled depression to ensure compaction of the layers and evacuation of air.
- Infuse the resin under the effect of this vacuum in order to evenly impregnate all of the reinforcement fabrics.
Main advantages of this process:
- Very good fibre/resin ratio,
- High and repeatable mechanical properties,
- Low porosity (0.5 to 2.5%),
- structural homogeneity,
- Possibility of producing very large parts with precise control of infusion parameters.
- Excellent working environment thanks to the reduction of solvent and volatile organic compound emissions.
At MULTIPLAST, this process is used for the following parts:
- Car simulators (AVSimulation),
- Bellmouths (SAFRAN LEAP engine),
- Production boats and Class40,
- Sails from the SolidSail project,
- Moulding tools,
- Civil engineering (Orthodox cathedral domes, Valberg planetarium, etc.),
- Components for the luxury goods industry (chandeliers, wall lights, stools, etc.)
