Abstract
This invention relates to needling of continuous glass yarn mats. The invention consists in subjecting the mat to the action, preferably simultaneous action, of needles of different diameters. Thus perforations of different dimensions, preferably regularly distributed, are made in the mat. This mat is intended to be used as reinforcement in composite materials with a base of thermoplastic resins, in particular in laminates.
