Disclosure herein are various forms of hybrid baseball bats comprising a wood shell having a radial wall and an outer radial surface profile defining a baseball bat. The wood shell having a central core with a central surface thereon extending from a distal end of the bat to the proximal end of the bat. The central surface being profiled with a taper that in some embodiments extends entirely through to the proximal end. A fibrous construct is housed in the central core and infiltrated with an epoxy resin for strength, shape adherence and bonding to the central surface. Disclosed are various manufacturing techniques for manufacturing hybrid bats including resin epoxy infiltration from removable or permanent core forced volume displacement means and/or high-pressure two-part epoxy injection means.

A structure can be formed by wrapping one or more densified, lignin-compromised wood veneers wrapped around a central axis. The wrapped wood veneers can form a circumferentially-extending wood wall. A glue can be provided on one or more surface portions of each wood veneer. The wood veneers can be lignin-compromised by in situ lignin modification, partial delignification, or full delignification. The circumferentially-extending wood wall can form a hollow member, for example, a tube, pipe, cup, tank, or bottle. Alternatively, the circumferentially-extending wood wall can surround a central member, for example, to form a rod, bat, club, or dowel.
