الخرسانة المسلحة بالألياف الزجاجية

تحتوي على ألياف قصيرة منفصلة موزعة بشكل موحد وموجهة بشكل عشوائي. تتغير طبيعة الخرسانة المسلحة بالألياف باختلاف الخليط والمواد الليفية والهندسة والتوزيع والتوجيه والكثافة. يُعرف المنتج أيضًا باسم الخرسانة المسلحة بالألياف الزجاجية

The design of glass-fiber-reinforced concrete panels uses a knowledge of its basic properties under tensile, compressive, bending and shear forces, coupled with estimates of behavior under secondary loading effects such as creep, thermal response and moisture movement.

There are a number of differences between structural metal and fiber-reinforced composites. For example, metals in general exhibit yielding and plastic deformation, whereas most fiber-reinforced composites are elastic in their tensile stress-strain characteristics. However, the dissimilar nature of these materials provides mechanisms for high-energy absorption on a microscopic scale comparable to the yielding process. Depending on the type and severity of external loads, a composite laminate may exhibit gradual deterioration in properties but usually does not fail in a catastrophic manner. Mechanisms of damage development and growth in metal and composite structure are also quite different. Other important characteristics of many fiber-reinforced composites are their non-corroding behavior, high damping capacity and low coefficients of thermal expansion.

Glass-fiber-reinforced concrete architectural panels have the general appearance of pre-cast concrete panels, but differ in several significant ways. For example, the GFRC panels, on average, weigh substantially less than pre-cast concrete panels due to their reduced thickness. Their low weight decreases loads superimposed on the building’s structural components making construction of the building frame more economical.

GFRC is incredibly versatile and has a large number of use cases due to its strength, weight, and design. The most common place you will see this material is in the construction industry. It’s used in very demanding cases such as architectural cladding that’s hanging several stories above sidewalks or even more for aesthetics such as interior furniture pieces like GFRC coffee tables.
