Description

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0007] The invention relates to a structure reinforcement fabric woven at a weft density in the range of 0.1-3 pcs/cm, comprising a polyethylene terephthalate (PET) yarn having a filament diameter in the range of 10-40 microns and a dtex value in the range of 900-4000.

[0008] The term structure used in the context of the invention includes all types of architectural works that at least require constructional activity. These works may include, but are not limited to, buildings, bridges, walls, pools, piers, bridges, tunnels, docks, and roads.

[0009] The field of application of the invention includes reinforcement of structures, particularly against earthquakes. It is mainly used to reinforce the bearing elements of the structure, such as columns, beams, slabs and masonry walls, and non-bearing elements, such as partition walls By applying the structure reinforcement fabric to the bearing/non-bearing elements of the structure with a suitable resin, for example by encircling/wrapping, the structure is reinforced.

[0010] The structure reinforcement fabric with PET yarns having the said properties has a significant production cost advantage over carbon fabrics. In addition, the structure reinforcement fabric with PET yam of the present invention has mechanical advantages over carbon fiber fabrics. While the elongation capabilities of the structure reinforcement fabric with PET yarn of the present invention are in the level of 20%, the elongation capability of carbon fiber fabrics is only around 2%. Its high elongation capability enables more horizontal movement of the applied structure. The seismic energy transmitted to the building is reduced by the horizontal movement and damage to the structure elements is prevented. Imparting high horizontal movement to the structure ensures that the structure remains undamaged in larger earthquakes. Also, even if the building is damaged, its load bearing ability can be maintained for a certain period of time, enough to prevent the loss of life. Another advantage of the invention is that it is more environmentally friendly than the prior art. It is possible to produce PET yarns with waste or recycled materials. PET fibers can be recovered by recycling PET bottles or vehicle tires. By ensuring that a structure remains undamaged in an earthquake and saving the energy needed to rebuild the structure, an environmentally friendly invention in many ways is realized by using low energy during its production and thereby emitting CO2 by means of allowing the use of recycled materials.

[0011] In one embodiment of the invention, the structure reinforcement fabric is woven together with at least one polymer from the polyolefin family with a high ductility level (elongation at break between 5% and 30%). PET yarns are extremely suitable for use with the said polymers. Depending on the type of polymer used and the frequency of use, the strength/performance of the structure reinforcement fabric can be adjusted according to the structure to which it will be applied. Polyamide 6, Polyamide 66, polyacrylonitrile (PAN), polyethylene naphthalate (PEN), polypropylene (PP) or polyethylene (PE) can preferably be used as high ductility polymers.

[0012] In one embodiment of the invention, the fabric is woven in one direction. Weaving the fabric in one direction increases the structure reinforcement performance of the fabric. Thus, a fabric is obtained without the need for cost-increasing applications such as coating the fabric that will be carried out to increase the structure reinforcement performance of the fabric.

[0013] The structure reinforcement fabric in the embodiments of the invention can be applied to structural elements by using a suitable resin of application, for example epoxy resin.
