         3 . The reinforcement structure according to  claim 1 , wherein the inner member includes one or more ribs projecting from the one or more walls to further define the one or more cavities. 
     
     
         4 . A reinforcement structure comprising:
 an inner member at least partially secured within a shell;   wherein the inner member is secured within the shell so that one or more abutment portions of the shell or inner member are positioned in receiving portions of the inner member or shell, respectively;   wherein the inner member includes one or more cavities formed by one or more walls of the inner member;   wherein the reinforcement structure further includes one or more brackets secured to the shell, the one or more brackets including one or more projections configured to mount the reinforcement structure to one or more additional structures.   
     
     
         5 . The reinforcement structure according to  claim 1 , wherein the shell includes a plurality of retaining features that contact an outer surface of the inner member to maintain the at least partial press-fit condition between the shell and the inner member. 
     
     
         6 . The reinforcement structure according to  claim 5 , wherein the retaining features are a plurality of undulations along an inner surface of the shell. 
     
     
         7 . The reinforcement structure according to  claim 1 , wherein the shell is a monolithically formed, enclosed structure having opposing openings at terminal ends of the shell. 
     
     
         8 . The reinforcement structure according to  claim 1 , wherein the shell includes one or more notches recessed from an outer surface of the shell. 
     
     
         9 . (canceled) 
     
     
         10 . The reinforcement structure according to  claim 1 , wherein the shell and the inner member are extruded separately and the inner body is inserted into the shell to create the press-fit condition. 
     
     
         11 . The reinforcement structure according to  claim 1 , wherein the shell and/or the inner member are pultruded. 
     
     
         12 . (canceled) 
     
     
         13 . (canceled) 
     
     
         14 . (canceled) 
     
     
         15 . The reinforcement structure according to  claim 3 , wherein the one or more ribs is a single rib extending between opposing walls of the inner member to form a pair of cavities. 
     
     
         16 . The reinforcement structure according to  claim 4 , wherein the shell, the inner member, or both are a fiber-reinforced composite material. 
     
     
         17 . The reinforcement structure according to  claim 16 , wherein the fiber-reinforced composite material contains one or more adhesive components. 
     
     
         18 . The reinforcement structure according to  claim 1 , wherein the shell and the inner member are secured to one another free of secondary fasteners, welds, adhesive, or combination thereof. 
     
     
         19 . (canceled) 
     
     
         20 . The reinforcement structure according to  claim 1 , wherein the inner member is a thermoactivated composite material. 
     
     
         21 . The reinforcement structure according to  claim 4 , wherein the inner member is at least partially secured to the shell by a male portion of the shell or the inner member being positioned within a female portion of the inner member or shell, respectively. 
     
     
         22 . (canceled) 
     
     
         23 . (canceled) 
     
     
         24 . The reinforcement structure according to  claim 1 , wherein the one or more cavities include an insert that locally reinforces the reinforcement structure.
