VACUUM-ASSISTED WET LAY-UP is a manual composite lamination technique combined with controlled vacuum application for the manufacture of technical composite parts.
This process involves manually laying reinforcement fabrics (carbon fibre, glass fibre, aramid) onto a table, a mould or between two panels to be joined. The reinforcements are then impregnated with epoxy resin, ensuring good bonding and mechanical performance suitable for structural applications.
The whole assembly is covered with vacuum-packing materials (tear-off fabric, perforated film, drainage film, vacuum bag), after which a vacuum is applied using a vacuum pump. This vacuum-packing process ensures that the folds are compacted, air bubbles are removed and the fibre content is optimised.
Key benefits of this process:
The polymerisation of epoxy resin, which takes between 8 and 24 hours depending on the hardener, produces lightweight, high-strength composite parts suitable for use in industry, transport, the marine sector and technical sports.
The vacuum-assisted wet lay-up process offers a flexible and cost-effective solution for the manufacture of prototypes, small batches and structural composite assemblies.
