دانلود Evaluation of Mechanical Properties of Hybrid Fiber Reinforced Polymer Composites and their Architecture

Abstract

Traditional  fiber  reinforced  polymer  (FRP)  composite  that  is  often  fabricated  from  single  type  of  reinforcement  has  shown  its ability  to  replace  the  conventional  metallic  material  counterparts.  However,  due  to  several  stringent  requirements  on  ductility,  this  has  affected  the  performance  of  FRP  composites  for  the  structural  applications.  Therefore,  hybrid  composites,  which combine two or more fiber reinforcements, have been introduced in order to overcome the short of traditional FRP composites.  This  paper  investigates  the  mechanical  properties  of  three  different  arrangements  of  hybrid  composites  made  from  glass  fiber  (plain-woven  and  stitched  bi-axial  ±45 ̊)  and  plain-woven  carbon  fiber.  Vacuum  assisted  resin  transfer  moulding  method  was employed to fabricate the hybrid composite panels. Mechanical properties such as tensile strength, flexural strength and volume fraction  of  the  hybrid  composites  were  determined  per  ASTM  standards.  Experimental  results  indicate  that  the  [CWW]6 arrangement,  where  C  and  W  are  weaved  carbon  fiber  and  glass  fiber  respectively,  were  superior  in  terms  of  mechanical properties.
