Fiberglass atomic structure
WebCarbon fibers or carbon fibres are fibers about 5–10 micrometres in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion. WebNylon is a generic designation for a family of synthetic polymers composed of polyamides (repeating units linked by amide links). Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes.: 2 Nylon polymers can be mixed with a wide variety of additives to achieve many property variations.

WebFibreglass is an excellent example of a relatively modern composite material (Invented in 1938 by Russel Games). In industry it is often referred to as Glass Reinforced Plastic (GRP). GRP is composed of strands of glass. Each individual glass fibre is very fine with a small diameter, and they are woven to form a flexible fabric. WebGlass fiber is made by drawing molten glass into fine fiber thread, which is a smooth and soft inorganic fiber with high strength in diameter ranging 9-18 μm. It is also combined well with synthetic resin into reinforced material. Glass fiber products such as glass fiber fabric or glass fiber mat are adopted in the production of GRP.
WebJan 1, 2009 · In the absence of long-range order within the atomic structure of a glass, the material solidifies in an amorphous arrangement. The polymeric nature of the chain molecules in organic polymers and inorganic silicates means that on cooling the viscous ‘melt’ there is insufficient time for crystallisation to occur and a random structure forms.
