Hey,

Searching the internet to learn a bit more about composites, I found that:

A-Stage and B-stage.

It seems to be related to resin used in prepregs... But i could not find any explanaition.

Anyone can help ?

Hi Joe,


A-Stage: Not a term often encountered but this describes resin in the earliest stages of the curing reaction, essentially in the case of most resins, when you first mix the resin and it is in a full liquid state. It will disperse easily with solvent.


B-Stage: This is essentially 'half-cured' resin, the resin will have increased in viscosity greatly, it may not disolve into solvents easily. However it will soften with heat and will feel 'tacky' to the touch. Most Prepreg carbon fibres are impregnated with B-staged resin.

Thanks for the answer.
