<p>This  research  included  the  study of  the effect  of  reinforced  glass fibers  on  fatigue  properties  for composite materials. Polyester  resin  is used  as  connective  material(matrix) in two types  of  glass  fibers  for reinforced. The  first  type  is regular  glass fibers  (woven  roving) with the  directional(0-90), the second  is  glass  fibers  with  the  random  direction. The first type is the panels with regular reinforced <br />(0-90), and with number of layer (1,2).</p><p>The  second  type  is  the  panels with random  reinforced  and  with  number  of  layers (1,2). The  results  and  the  laboratory  examinations  for  the samples  reinforce  with  fibers  have  manifested (0-90)  that there  is  a decrease  in the number  of  cycles  to the  fatigue  limit  when  the  number  of  reinforce  layers  have  increased . And  an elasticity of this  type  of  samples  are decreased  by  increasing  the number  of  reinforced  layers  with  fiber  .We  find  the  random  reinforced  number  of  fatigue  cycles  for the samples  with  two  layers  of  random  reinforced  are  decreased  more  than the samples  with  one  layer of random  reinforced .</p>
