Abstract: Recent developments of investigation into mechanical behaviors of 3D braided composites at home and abroad are summarized.The emphasis is placed on the recent developments of mechanical properties of three dimensional braided composites in this field, in which the experimental and theoretical investigations into three dimensional braided composites are included.Experiment investigations most concentrated on testing the mechanical properties of 3D braided composites with different braiding parameters and load.However, some information about the mechanics model are introduced in theoretical studies.Finally, some problems in present studies are concluded and future investigating trends are proposed.
