Abstract
Official abstract text for this publication.
A curable resin system comprising 1) an epoxy component having a polyglycidyl ether of a polyphenol having an epoxy equivalent weight of up to about 190; and 2) a hardener component comprising polyethylene tetraamine mixture; wherein the epoxy component has a viscosity of less than 9000 mPa·s at 25° C.
First claim
Opening claim text (preview).
1 . A curable resin system, comprising 1) an epoxy component having polyglycidyl ethers of a polyphenol having an epoxy equivalent weight of up to about 190; 2) a hardener component comprising polyethylene tetraamine mixture; wherein the epoxy component has a viscosity of less than 9000 mPa·s at 25° C. 2 . The curable resin system of claim 1 , wherein the polyglycidyl ethers of a polyphenol comprises no more than 1 wt. %, based on total weight of the polyglycidyl ethers of a polyphenol, of mono hydrolyzed resin content. 3 . The curable resin system of claim 1 , wherein the weight ratio between the epoxy component to the hardener component is between 100:11 to 100:20. 4 . The curable resin system of claim 1 , wherein at least 40% of the weight of the polyethylene tetraamine mixture is a linear triethylene tetraamine with a chemical structure of: H 2 N—CH 2 —CH 2 —NH—CH 2 —CH 2 —NH—CH 2 —CH 2 —NH 2 5 . The curable resin system of claim 1 , wherein the hardener component comprises over 90 wt. % of triethylenetetramine and the rest being 1,4-di-azabicyclo[2,2,2]octane, based on the total weight of the hardener component. 6 . The curable resin system of claim 1 further comprising an internal mold release agent. 7 . A cured fiber-reinforced composite made from the resin system of claim 1 .
