Hi,

I'm prototyping a project which involves a fibreglass core faced with fabric.
The workflow that i would like to use is similar to prepreg, in that i want to partially cure the core, before being able to trim it to size and execute the final layup in a clean environment (without resin dribbling all over the place - particularly around the edges).

As opposed to typical prepreg, i don't have any concerns about visual appearance of the mat, its strength or weight, or optimizing resin impregnation. So expensive carbon fibre products are unnecessary for me.
I need this to be a cheap and low tech method.

Essentially i want to lay up three layers of fibreglass on a flat surface, achieve a partial cure, then cut them to size accurately with shears and transfer to a curved mould with the fabric facings (which are not too permiable and will probably have a thin layer of resin applied to their insides) for full cure.

Does this sound realistic? 
If so what resin would i use, and how would i achieve the desired partial cure (by following a particular timing, or refridgerating etc)? 

Many thanks,

Trev
