TPU/PVC/PU coated carbon fiber fabric for bags suitcases

Carbon fiber fabric reinforced laminated veneer lumber (RLVL) pieces were  prepared  by  using  heat-treated  beech  (Fagus  orientalis  Lipsky) veneers with  polyurethane  (PU)  adhesive as the  binder.  Carbon fiber fabric was tested in three different locations with solid material and non- reinforced samples (on the bottom adhesive line, upper adhesive line, and upper and bottom adhesive lines-symmetrical). Prior to the manufacture of LVL and RLVL, heat treatment was conducted in a laboratory oven at three temperatures. These temperatures were  150,  170,  and  190  °C. Tests were  performed  on  LVL  and  RLVL  to  determine  their  air-dried density, modulus of rupture (MOR), and modulus of elasticity in bending (MOE). Experimental test results showed that reinforcement with carbon fiber increased the air-dried density, MOR, and MOE. In addition, carbon fiber fabric placed symmetrically close to bottom and upper surfaces gave the highest MOR and MOE values. However, locating the carbon fiber fabric  closer to the  bottom  surface  tended  to give  higher  mechanical properties for the reinforced LVL.
