Abstract
A nano-enhanced matrix material includes a matrix film carrying one or more nano-additives. The nano-additives may be oriented transversely relative to the matrix film. A composite structure includes a plurality of composite laminate plies and one or more matrix films carrying one or more nano-additive materials, the matrix films being positioned between composite laminate plies. Composite structures may include ball bats, and the matrix films with nano-additive materials may be positioned in selected portions of ball bats, such as wherever improved strength or resistance to fatigue is desired.
Claims19
A ball bat comprising:
- a handle;
- a barrel attached to or continuous with the handle, the barrel comprising a plurality of composite laminate plies forming a wall of the barrel;
- and
- one or more nano-additive materials positioned in a resin-rich area between at least two of the composite laminate plies, wherein some of the nano-additive materials are oriented transversely to the at least two of the composite laminate plies.
A ball bat comprising:
- a plurality of composite laminate plies;
- and
- a matrix film carrying one or more nano-additive materials, the matrix film being positioned between at least two composite laminate plies of the plurality of composite laminate plies;
- wherein some of the one or more nano-additive materials are oriented transversely to the at least two composite laminate plies.
