Abstract
The present disclosure relates to epoxide containing compounds comprising three benzene units linked by bridging groups. The disclosure also relates to the production of curable epoxy resin formulations comprising said epoxide containing compounds, and their possible incorporation into composite materials such as fibre reinforced composites. Possible methods for formulating the compounds epoxide containing compounds, as described herein, are also disclosed.
Claims20
A method of forming a fibre reinforced material, the method comprising:
- introducing a curable epoxy resin formulation with a fibrous material to form a mixture,
- wherein the curable epoxy resin formulation consists essentially of a curable epoxy resin and an amine curing agent,
- wherein a ratio of the amine curing agent and the curable epoxy resin is a stoichiometry of from 0.95:1.0 to 0.6:1.0,
- wherein the curable epoxy resin consists essentially of a compound of Formula 1:
- wherein each X1 is O, each R1 is an epoxide group, and each R2 is hydrogen, wherein the epoxide group is
- and
- curing the mixture at an elevated temperature to form the fibre reinforced material comprising a cured epoxy resin.
