Process Description
Resin Infusion uses a one-sided tool and a vacuum bag which contain a layup of cloth and perhaps other core material.
A feeder/runner system is used to permit resin to enter the layup and flow through the fibrous material.
Typical Applications
Radomes, cowlings, fairings, enclosures, large structural components.
Resin Infusion Advantages
- High fiber content and low void content
- Excellent adhesion to core materials
- Lower cost of raw materials versus Pre-Peg Layup
- Minimal labor required for large components
- Lower capital equipment requirements than autoclave
- Low emissions from resin
- High quality repeatable processes
Resin Infusion Disadvantages
- Poorer surface on vacuum bag side of part
- Some process development needed to optimize flow of resin
