The term "resin rich" refers to a composite material that is?

The term "resin rich" indeed refers to a composite material that has a higher proportion of resin relative to reinforcing fibers. This situation indicates that the composite is saturated with resin yet may not contain enough reinforcing fibers to achieve optimal strength and structural properties. The excess resin can lead to a number of issues, including increased weight, reduced tensile strength, and potential for poor bonding performance, as the fibers are essential for providing the strength and stiffness to the composite material.

In composite manufacturing, it's crucial to maintain a balanced ratio of resin to fibers to ensure the material properties are maximized for its intended application. A resin-rich composition does not fulfill this critical requirement, which is why understanding the implications of such a term is important in the field of composite materials.
