Core-shell hybrid pre-preg tow for lightweight composite truss

A robust pre-impregnated hybrid tow for manufacturing lightweight composite truss has been developed and characterized. The hybrid tow is in a core-shell structure where the core is epoxy pre-impregnated carbon fibers and shell is a protective braided jacket. The hybrid tow has good conformability which allows it to be used in braiding process for fabricating complex shape lattice structures. The mechanical properties of the hybrid tow are...
