Fibrous Structures

For the development of AuxDefense´s various products the following fibrous structures will be used:
  • Conventional or planar structures (2D)
In a planar 2D structure, fibers are oriented in a plane, so their production does not require any special adaptation of existing technology used for the production of conventional fibrous structures. However, despite being produced through conventional preocesses, this kind of structure can also be used in many technical applications, depending on the type of fiber used.
  • 3D structures
3D structures are groups of integrated fibers organized in a multiaxial orientation. These structures are used in response to the need for materials capable of resisting multidirectional strain under extreme conditions. When compared to 2D structures, 3D structures offer high mechanical properties in the x, y and z directions. This structures' classification should consider the linearity of the reinforcement in each direction, it's continuity, the beam size's density in each direction and the geometric characteristics of the fibers' beams, whether they are linear or curved and the curvature's degree. Generally 3D structures can be layered or sandwich.
  • Monoaxial or unidirectional structures
Monoaxial or unidirectional structures are formed by a high number of fibers oriented in parallel in a single direction. The most common directions are 0∘ (longitudinal) and 90∘ (transversal). These structures may be achieved through different production technologies such as weaving, knitting, sewing and/or rolling.
