Thermoplastic epoxy materials with core shell phase

A composite article, comprising:

• i) at least one fibrous layer;
• and
• ii) a matrix material in direct contact with the at least one fibrous layer, the matrix material comprising a monoethanolamine and a diepoxide, wherein the monoethanolamine and diepoxide react to form a thermoplastic condensation reaction product during processing;
• wherein the matrix material includes hydroxyl moieties and epoxy moieties which react to form a generally linear backbone polymer chain with ether linkages;
• wherein the matrix material contains an additive;
• wherein the additive is a toughening agent comprising a core shell material present in an amount of at least 5.7% by weight of the matrix material;
• wherein as a result of the amount of core shell material, the matrix material in its green state has a viscosity as measured according to ISO 6721-10:2015, at a temperature of 170° C. at 11 radians/second (rad/s) of at least 3060 Pa·s and a shear strength as measured by ISO 4587:2003 of at least 14.9 Mpa;
• wherein during a molding process, at least a portion of the matrix material liquifies, and the liquified matrix material and the additive impregnate the at least one fibrous layer;
• and
• wherein the liquified matrix material solidifies resulting in the reaction product.
