Dichloromethane or methylene chloride
Fibreglass resin is a polyester.
Polyester resin is a thermosetting resin, generally a copolymer
it
No
as polyester resin is a bi-product of oil so if the prices of oil rise then it is definite that the polyster resin price will also rise.
Epoxy resin cannot be cured without hardener because the hardener is necessary to initiate the chemical reaction that causes the resin to harden and cure.
yes
Yes, it is possible.
It will not mix.
Acetone will work fairly well to remove the polyester resin--until the resin sets. Trichloroethane (e.g., ZipStrip) will soften the cured resin, possibly enough to remove it. Always try it on an inconspicuous spot before you commit to treat the whole garment. I know of a guy who had to wear a towel home because the acetone turned his polyester trousers into what looked like snot when he soaked them.
The poission ratio of orthophthalic polyester resin it's 0.37.
Prepreg is a reinforcement material (such as carbon fiber or fiberglass) pre-impregnated with resin, while molding compound is a mix of resin, fillers, and other additives that is formed into a specific shape before curing. Prepreg is typically used in composite manufacturing processes where the resin is only cured when heated, while molding compound can be cured using heat, pressure, or a combination of both.
