Abstract
Disclosed herein are toughened composite materials, and methods for manufacturing thereof. At least one interleaf toughing particle and at least one polymer veil are used to synergistically increase the toughness of a fiber/polymer composite. The at least one interleaf toughening particle and at least one polymer veil can be located in the interlaminar sections of the composite material.
Claims15
A toughened composite material comprising:
- a first layer comprising a plurality of reinforcing fibers arranged in a fiber configuration and embedded in a polymer matrix;
- and
- a second layer contacting and at least partially covering the first layer, the second layer comprising a laminating matrix, wherein the laminating matrix comprises an interlaminar layer and at least one toughening particle embedded in the laminating matrix;
- wherein the interlaminar layer and the at least one toughening particle are selected in combination to synergistically provide the composite material with improved toughness.

A method of forming a composite material comprising:
- providing a first layer comprising a prepreg;
- at least partially contacting and covering the first layer with a second layer comprising an interlaminar layer;
- laminating the first and second layer with a third layer to form a laminated prepreg, the third layer comprising at least one toughening particle embedded into a laminating matrix;
- and
- curing the laminated prepreg to form a composite material;
- wherein the interlaminar layer and the at least one toughening particle are selected in combination to synergistically provide the composite material with improved toughness.
