The authors have previously worked on a method of microscopic 3-D analysis by FEM for plain weven fabric reinforced plastics. In the present investigation, it was proved that our method can be extended for a twill woven fabric one too. Through the present analysis, it was found that the highest value of maximum principal strain is generated in the matrix near the end of the transverse strand which just crosses over longitudinal one. From the present result on the transverse strand which just crosses over longitudinal one. From the present result on the elastic module and the previous one on the plain woven reinforced plastics by 3-D FEM analysis, it was clarified that the former has an advantage over the latter in a high Young's modulus net on the other hand, the former's Poisson's ratio is bigger than the latter's.
