摘要：

The in-plane shear strength of tri-axial braided composite materials was measured for three different braid angles (30 degrees, 45 degrees, and 60 degrees) and two strain rates (0.001 s(-1); 3 s(-1)) using the three-rail shear test. The in-plane shear strength was found to be sensitive to both-the braid angle and the strain rate. An increase of braid angle resulted in a reduction of shear strength, whilst an increase of loading rate resulted in an increase of shear strength of 8%-17%, depending on the braid angle.
