Abstract
The present invention relates to flexible, three-dimensional articles consisting of a flexible, two-dimensional, unimpregnated, braided structure based on yarns or tows preferably having a high modulus of elasticity and possessing a varying cross-section. These articles are intermediates in the production of shaped articles which are both strong and light.
