A new structural model was built to study the bending properties of three-dimensional curved shallow-
crossing linking woven composites (3D composites) using mapping software Pro/ Engineer. The distribution of stress
& strain on fibers,resin and 3D composites, as well as the failure mode, was discussed and predicted, respectively,
under bending loads of 5 mm displacement using finite element software ANSYS workbench. The results show that un-
der the bending loads the most easily damaging parts of the 3D composites occurred on the point-surface contacts,
where the samples contacted with the up and down pressure heads,the main loads were supported by reinforced fibers
and the minor loads are supported by matrix resin. The main failure mode of the 3D composites is resin fracture under
bending loads of 5 mm displacement.
