Problems solved by technology
[0009] The currently known and practiced methods for producing carbon fibers, basalt fibers and glass fibers as concrete reinforcements do not allow effective protection against mechanical loads against fire
While basalt fibers and glass fibers are inherently non-flammable, the matrix connecting the fibers can be combustible or can be altered at high temperatures such that it no longer fulfills its prescribed protective function

Embodiment Construction
[0030] exist figure 1 and 2 A first exemplary embodiment for the production of fiber profiles for high fire protection requirements is shown in . They show a schematic diagram of a pultrusion process according to the invention with two matrix containers containing matrices of different viscosities. Exemplary fiber profiles as end products are in image 3 , 4 and 5 are shown.
[0031] Here the raw material goes through the following steps:
[0032] 1. A fiber sliver 2 made of carbon fibers is unwound from a supply reel 1 with the desired number of fiber slivers. For display purposes, figure 1 Only 3 supply reels 1 are shown. In practice, the finished fiber profile 20 comprises a plurality of individual fiber strands.
[0033] 2. The individual fiber strands 2 are assembled into a fiber bundle 4 by means of rollers 3 and known suitable customary guides until the specified thickness 20 of the desired fiber profile 20 is reached.
[0034] 3. The fiber bundle 4 produced in...

Abstract
The invention relates to a fiber profile for high fire protection requirements, which can be used in particular for producing high-strength reinforcements for the construction industry. The object ofthe invention is to provide a fibrous profile and a method for producing the same. Technical properties of the fibrous profile should be significantly expanded and optimized for new fire safety applications. In particular, the surface of the fibrous profile should be hardened and protected against destructive heat in a reasonable period of time. The fiber profile comprises a fiber rod embedded ina matrix, said fiber rod being made of a fiber composite material, in particular carbon fibers, basalt fibers and glass fibers. According to the invention, the fiber strands are surrounded by a matrixmade of an aqueous metal silicate solution (water glass). The fibrous profile may have a coating made of an alkali-resistant, highly heat-resistant sheet-like coating material applied to a matrix. Abrasive sheets and / or glass sheets and / or mica sheets are used as coating materials.
Description
technical field [0001] The invention relates to a fiber profile for high fire protection requirements, which can be used in particular as a reinforcement profile for the production of high-strength reinforcements for the construction industry. Fiber profiles are especially suitable for use in concrete structures such as skyscrapers or bridges that must meet high fire protection requirements. The invention also relates to a method for producing fiber profiles produced in a pultrusion process from fiber strips embedded in a matrix, said fiber strips being made of fiber composite material, in particular carbon fibers, Made of basalt fiber or fiberglass material. Background technique [0002] When manufacturing carbon fiber strips, glass fiber strips or basalt fiber strips, usually a plurality of single fibers are brought together and encapsulated with a matrix into one or more bundles. In the following, the different fiber materials are named under the general term "fiber". ...
