What are the characteristics of glass Fibre reinforced composites?
Glass-fiber composite is a type of fiber-reinforced polymer composites. Glass-fiber composite holds good properties such as low density, high strength, and easy processing, so widely used in aerospace, automotive, and construction.
Is the unique property of the glass fiber?
Explanation: Glass fibres have a unique property as a transmission medium which enables their use in the communication. The major transmission characteristics are dispersion and attenuation.
What are the main properties of composites?
However, as a class of materials, composites tend to have the following characteristics: high strength; high modulus; low density; excellent resistance to fatigue, creep, creep rupture, corrosion, and wear; and low coefficient of ther- mal expansion (CTE).
What are glass fibers made of?
The glass fiber process Textile-grade glass fibers are made from silica (SiO2) sand, which melts at 1720°C/3128°F. SiO2 is also the basic element in quartz, a naturally occurring rock.
What are glass fibre composites?
Glass-reinforced plastic (GRP) is a composite material or fiber-reinforced plastic made of a plastic reinforced by fine glass fibers. Like graphite-reinforced plastic, the composite material is commonly referred to as fiberglass. The glass can be in the form of a chopped strand mat (CSM) or a woven fabric.
What is in glass fibre?
Glass fibers are formed from melts and manufactured in various compositions by changing the amount of raw materials like sand for silica, clay for alumina, calcite for calcium oxide, and colemanite for boron oxide.
What are properties of fibres?
The type of fiber is the most crucial specification which determines important properties such as strength, durability, handle, elasticity, dyeability, luster, friction properties, moisture absorbance, heat isolation and abrasion resistance; all the physical and chemical properties of fibers and their end-products.
What are the properties and processing of composites manufacture of Fibres?
Fiber-reinforced polymer composite offers not only high strength to weight ratio, but also reveals exceptional properties such as high durability; stiffness; damping property; flexural strength; and resistance to corrosion, wear, impact, and fire.
What is composite and its properties?
A composite material is a combination of two materials with different physical and chemical properties. When they are combined they create a material which is specialised to do a certain job, for instance to become stronger, lighter or resistant to electricity. They can also improve strength and stiffness.
What are the distinct characteristics and properties of a glass?
The main characteristics of glass are transparency, heat resistance, pressure and breakage resistance and chemical resistance. The hardness of float glass is established according to Knoop.
What are the properties of a parallelogram?
A parallelogram is a closed four-sided two-dimensional figure in which the opposite sides are parallel and equal in length. Also, the opposite angles are also equal. Learning the properties of a parallelogram is useful in finding the angles and sides of a parallelogram. The four most important properties of a parallelogram are:
Are the opposite sides of a parallelogram congruent?
Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Each diagonal of a parallelogram separates it into two congruent triangles.
What are the physical properties of glass fiber filaments?
General physical properties of glass fiber filaments: High tension-endurance: the tension-resistant is about twice as steel of unit weight. Good size stability: the ratio of elongation is about 3% ~ 4%. Good heat-endurance: it have the 50% ability of tension-endurance however the temperature of 340℃.
What are the consecutive angles of a parallelogram?
The consecutive angles of a parallelogram should be supplementary (180°). The 7 important theorems on properties of a parallelogram are given below: A diagonal of a parallelogram divides the parallelogram into two congruent triangles.
