Abstract
A system and method for manufacturing a hybrid composite laminate system. The method includes positioning a plurality of non-natural fiber layers comprising at least one of: glass fibers and carbon fibers, preparing at least one natural fiber layer, and positioning the at least one natural fiber layer adjacent to, and in contact with at least one of the plurality of non-natural fiber layers. The method also includes increasing a first structural damping coefficient of the hybrid composite laminate system to be more than a second structural damping coefficient of a reference composite laminate without the natural fiber layer.

A hybrid composite laminate system comprising:
- a plurality of non-natural fiber layers comprising at least one of:
- glass fibers and carbon fibers;
- at least one natural fiber layer positioned adjacent to, and in contact with at least one of the plurality of non-natural fiber layers,
- wherein a first structural damping coefficient of the hybrid composite laminate system is higher than a second structural damping coefficient of a reference composite laminate without the natural fiber layer.
A method of manufacturing a hybrid composite laminate system, the method comprising:
- positioning a plurality of non-natural fiber layers comprising at least one of:
- glass fibers and carbon fibers;
- preparing at least one natural fiber layer;
- positioning the at least one natural fiber layer adjacent to, and in contact with at least one of the plurality of non-natural fiber layers;
- and
- increasing a first structural damping coefficient of the hybrid composite laminate system to be more than a second structural damping coefficient of a reference composite laminate without the natural fiber layer.
A method of retrofitting a structural component, the method comprising:
- identifying an application part of the structural component for retrofitting;
- applying a retrofittable hybrid composite laminate system to an interior or exterior surface of the application part of the structural component;
- and
- increasing a first structural damping coefficient of the structural component more than a second structural damping coefficient of a reference structural component without the natural fiber layer.
