       9 . The reinforced wood panel according to  claim 1 , wherein the first lignocellulosic layer has an MOE value of about 0.5 to 1.2 mmpsi, preferably about 0.8 to about 1.15 mmpsi. 
   
   
       10 . The reinforced wood panel according to  claim 1 , wherein the prepreg comprises reinforcing fibers and resin, the fibers being selected from the group comprising glass fibers, carbon fibers, armaric fibers, wood fibers, and bamboo fibers. 
   
   
       11 . The reinforced wood panel according to  claim 1 , wherein the prepreg layer has a sufficiently high MOE value so that when incorporated into the reinforced wood panel, the reinforced wood panel has an MOE of about 1.3 to about 2.5 mmpsi. 
   
   
       12 . A reinforced wood panel comprising: a first lignocellulosic layer, a first prepreg layer, and a second prepreg layer, wherein the first lignocellulosic layer forms a core layer disposed between an upper surface layer formed by the first prepreg layer and a lower surface layer formed by the second prepreg layer. 
   
   
       13 . The reinforced wood panel according to  claim 12  having a MOE of about 1.3 to about 2.5 mmpsi. 
   
   
       14 . The reinforced wood panel according to  claim 12  wherein the lignocellulosic layer is in the form of a wood composite material selected from the group including plywood, fiberboard, and OSB. 
   
   
       15 . The reinforced wood panel according to  claim 12  wherein the lignocellulosic layer is in the form of OSB. 
   
   
       16 . The reinforced wood panel according to  claim 12  wherein the first prepreg layer has a thickness of between 0.010 inch to 0.250 inch 
   
   
       17 . The reinforced wood panel according to  claim 12  wherein the first prepreg layer has an MOE value of 1.7 to 50 mmpsi. 
   
   
       18 . The reinforced wood panel according to  claim 12 , wherein the lignocellulosic layer has a thickness of about ¼″ to about 2.5″, preferably in the range of ⅜″ to 1.75″, more preferably in the range of 0.7″ to 1.5″. 
   
   
       19 . The reinforced wood panel according to  claim 12 , wherein the lignocellulosic layer has an MOE value of about 0.5 mmpsi to 1.2 mmpsi, preferably about 0.8 mmpsi to about 1.15 mmpsi. 
   
   
       20 . An I joist comprising a first flange interconnected by a webstock to a second flange; wherein the first flange is cut from a reinforced wood panel comprising a first lignocellulosic layer, and a prepreg layer. 
   
   
       21 . The I joist according to  claim 20  wherein the first lignocellulosic layer is in the form of a wood composite material selected from the group including plywood, fiberboard, and OSB. 
   
   
       22 . The I joist according to  claim 20  wherein the first lignocellulosic layer is in the form of OSB.
