The present invention relates to the development of carbon fiber carbon nanotubes reinforced polymer composites for high strength  structural applications. It is very difficult to incorporate higher amount of carbon fiber >60 vol% in any of the polymer matrix. Beyond  this loading the mechanical properties of these composite starts deteriorate. Therefore, further improvement in the mechanical  properties is not possible. Herein, a novel method is developed to fabricate the hybrid carbon fiber epoxy composites reinforced with  multiwalled carbon nanotubes. The flexural strength of the hybrid composites (45 vol% CF+CNT) was achieved more than 600 MPa  which is more than 35% over pure carbon fiber/epoxy composites (50 vol% CF). These high strength hybrid composites can be used  in wind mill blades, turbine blades, sport industries, automobile and airframe.
