The properties of metal are well studied, and it is almost impossible to radically improve them somehow. Polymers, on the other hand, are experiencing a dawn in popularity and the search for new applications. Fiberglass reinforcement UralArmaprom on https://rnd.uralarmaprom.ru/, used for construction, has shown that it can compete with ordinary steel. In addition, the polymer has a wide range of characteristics applicable to the construction of civil and industrial facilities.
The structure of the new bar
The bar does not consist of a homogeneous material, it is a full-fledged composite. It is this property of the fittings that allowed achieving higher performance characteristics. Not just resistance to temperature extremes and lack of corrosion. If you divide the rod into its component parts, then you should highlight:
1. Parallel or curled fibers.
2. Internal filler in the form of a polymer two-component resin.
3. Outer fiberglass layer with coils of additional fibers.
Polymer reinforcement repeats the appearance of a classic material. But, in terms of their strength and technical characteristics, they surpass them. There are alternative types of external coatings, in the form of abrasive spraying.
Fundamental properties
Research of fiberglass reinforcement was carried out by numerous independent researchers. They all showed approximately the same results. Of all the variety of conclusions, it is worth highlighting the most important:
- at least 9 times lighter than steel analogues;
- practically does not corrode under normal operating conditions;
- "cold bridges" are almost completely excluded;
- ease of transportation, storage and duration of operation;
- does not conduct electricity at all.
Important: use in large-scale construction lightens the entire structure as a whole. The pressure on the foundation never exceeds the permissible limits.
