In order to solve the limitation of three-dimensional braiding in making preforms of complex shape,the technology of stitching joint three-dimensional braided composites is presented,and the creative feature as well as problems should be solved are expounded.

Effects of through thickness stitching on Mode II interlaminar fracture toughness( G II ) and modes of delamination of composite laminates were investigated by performing end notched flexure(ENF) tests.

The effects were investigated of stitching directions, layup sequences and environmental factors on tensile and compressive properties.

High strength glass yams,Kevlar-29 fiber yams and T300 3K fiber yams are used to stitch glass section-cloth respectively.

By using the algorithm, we can not only stitch multiple trimmed surfaces but also repair those initial CAD defects such as gap, overlap as.

The present state of research and development of textile composite was introduced, and the stitched/RTM composite and it s advantages were described.
