In composites, this is the binding material that holds the composite together?

Explanation:
Matrix is the binding material in a composite. It surrounds and binds the reinforcing material (like fibres or particles), holds them in place, and distributes loads between them. It also protects the reinforcement from moisture, heat, and chemicals and helps define the shape and surface finish of the final product. The reinforcement provides the main strength and stiffness, but it needs the matrix to stay together as a single unit. Examples include epoxy resin binding carbon fibre or polyester resin binding glass fibre. Planned obsolescence and repair aren’t involved in the role of this binding material.
