How to Do Vinyl-Ester Resin Infusion
Vacuum Infusion is an attractive way of building composite parts because it offers greater worker safety. Furthermore, vacuum Infusion can also be more cost-effective and faster than autoclave processes; thicker laminates with cored cores can also be produced more effectively this way. However, for those new to vinyl-ester resin infusion or with existing tooling that isn't optimized for it can present some challenges but there are plenty of helpful resources out there to guide their way through.


One of the keys to successful vinyl-ester infusion is choosing an appropriate resin. Look for one with low shrinkage and viscosity, plus reliable degassing equipment like a pump with adjustable throttle valve and degassing equipment with temperature control features like point-and-shoot infrared thermometer gun that lets you monitor its reaction with resin buckets as it cures.

Woven fabrics should only be used if they're reinforced with unwoven reinforcements as their tows tend to cross-over each other forming areas that don't compact well and act as potential places for air trapped beneath. Core ramps should still be considered essential when creating parts using infusion; ensure they are well tapered at every spot where core thickness changes or disappears entirely.
