Unidirectional composite with sinusoidal cross section tows

Unidirectional composite with rectangular cross section tows

and Mesh Option #2

Fill tows in a unidirectional composite with mixed cross section tows

Here the top part of the tow is sinusoidal while the bottom is flat

Fill tows in a unidirectional composite with trapezium cross section tows

Fill tows in a unidirectional composite with elliptical cross section tows and horizontal undulations

Here the horizontal undulations and tow spacing are controlled independently

Fill tows in a unidirectional composite with mixed cross section tows

Here the top and bottom parts of the tow are sinusoidal but with different geometrical parameters

3D fabric with five layers of alternating warp and fill tows interlaced with inclined through-thickness Z-tows

3D fabric with five layers of alternating warp and fill tows interlaced with vertical through-thickness Z-tows

Hybrid tow with transitioning cross sections

Here the cross section linearly transitions between two trapeziums, with each trapezium being the upside-down version of the other
