The Effect of Environment on Tensile Properties of Stitched and Unstitched Laminates (with a Hole)

Tensile tests are conducted on stitched and unstitched uniweave T300/QY9512 laminates (with a hole) in hygrothermal environment and normal environment. It is shown that in a normal environment stitching reduces the tensile strength of laminates and does not significantly alter the open-hole tensile...

Description
Summary:Tensile tests are conducted on stitched and unstitched uniweave T300/QY9512 laminates (with a hole) in hygrothermal environment and normal environment. It is shown that in a normal environment stitching reduces the tensile strength of laminates and does not significantly alter the open-hole tensile strength. The hygrothermal environment has a beneficial effect on the tensile strength of laminates and open-hole laminates, especially of stitched specimens. It is also noted that stitching direction has no effect on the tensile properties.
