"It’s the holy grail of infusion: an unsaturated polyester or vinyl ester resin that allows unlimited flow time to vacuum infuse very large, thick parts, cures on demand and produces parts with mechanical properties equivalent to epoxy. Sound impossible? In fact, it is now a reality."

New infusion regime for superthick laminates: Composites World

Figured I'd post this in case others hadn't seen it.

The article itself is a great discussion of the chemistry and problems faced by the use of resins in composite layups. I highly recommend a read-through just for a greater understanding of what you're dealing with when you use resins.

Cheers,
Serge.

Thanks! Very interesting.... I can see how the extended flow time of 70 hours is a huge plus for a homebuilder who is nervous about making a large part. On the other hand, I'm imagining some fairly complicated temperature controls (heating and cooling) to maintain the trigger temperature. Definitely something to keep an eye on when I get that far.
