Multi-Layer Woven Preforms for Composites
topic
Multi-layer woven preforms for composite reinforcement weave 3 to 20 or more layers of reinforcement yarn simultaneously with through-thickness binding yarns that interlace between layers to provide interlaminar shear resistance that laminated unidirectional prepregs lack, with 3D orthogonal weaving positioning warp, weft, and vertical through-thickness yarns in three mutually perpendicular directions creating the isotropic reinforcement architecture required for thick composite structures in aerospace, marine, and wind turbine applications.
Role
Extends woven fabric technology into the third dimension for structural composite applications where the through-thickness reinforcement of 3D woven preforms provides dramatically improved delamination resistance compared to laminated 2D fabric composites, enabling composite structures with complex geometry and required impact resistance that conventional lamination cannot achieve, with 3D weaving being an enabling technology for next-generation structural composites in aerospace and advanced engineering.
