Liquid resin infusion (LRI)

Overview

A process where dry carbon fibre material is laid into a tool. The carbon material can be pre-formed into 3D shapes. The resin is then injected according to precise requirements of temperature and pressure.

Advantages

• Single mould used – less cost
• Large volume parts with low cost tooling
• Good strength from pre-form
• Repeatable process
• Clean process
• Ambient curing
• Integrated solutions

Used on

• Integrated wing programme
• Next generation composite wing programme
