Euro-Composites Corp. (Elkwood, VA, US) introduced a new 3D-capable aramid honeycomb core it calls ECA-3D. Instead of hexagonal cells, the cell shape is more teardrop-like, which provides high formability with multi-directional curvature without collapsing the cell walls, while maintaining high shear strength, says the company. Applications include any type of cored part where acute or compound curvature is required, such as wings, stabilizers, radomes and more. Euro-Composites adds that the product can greatly reduce manufacturing costs, since heat forming of traditional hexagonal core can be eliminated.
