Die erste Gruppe umfasst Materialien, bei denen räumliche Bindungen aufgrund der Krümmung aller oder eines Teils der Fasern in einer Richtung gebildet werden. Diese Materialien werden mit dem traditionellen Zweifadensystem hergestellt: gekrümmte Kette und gerader Schuss.

Die zweite Gruppe umfasst Materialien, deren räumliche Verbindungen durch das Einbringen von Fasern in dritter Richtung hergestellt werden. Diese Verbundwerkstoffe werden durch ein Dreifadensystem in einem rechteckigen oder zylindrischen Koordinatensystem gebildet. Die Fasern können in drei Richtungen zueinander orthogonal oder in eine der Verstärkungsebenen abgewinkelt sein.

Three-dimensional reinforced preforms can be created on special weaving machines according to a carefully developed technological program. The photo below shows a shuttle weaving automated complex developed and manufactured by LLC "SmartService". The use of three-dimensional reinforced preforms for the manufacture of composite materials allows to increase by times the strength of separation in the transversal direction and significantly increase the shear resistance compared to the strength of layered materials.

Sizeable, three-dimensional reinforcing fillers obtained by 3D weaving can be either thin-walled or thick- walled. Thin-walled have a complex profile and are designed to form light sized, thin-walled hollow panels or thin-walled profiles that can change their profile, structure and thickness along the length of the profile.

Thick-walled (solid) is a sizeable reinforcing structure for forming sizeable plates or mats, the entire content of which is filled with reinforcing threads located in three perpendicular directions, forming an orthogonal reinforcement structure. It is also possible to have a more complex structure, when threads that run at an angle to the vertical are added to the orthogonal structure. Products formed on the basis of such reinforcing PCM structures can be subjected to additional mechanical processing, taking into account the location of the reinforcing elements inside it.
