Steel fibers of 13 mm length . Glass fabrics retain 50% of room temperature tensile strength at The 1,2-(ortho-) or 1,3-(meta-) linkage produces an angle in the chain, which also disturbs crystallinity.Such copolymers are advantageous for certain molding applications, such as thermoforming, which is used for example to make tray or blister packaging from co Steel fibers, glass fibers, and steel-glass hybrid fibers were used to prepare the FR-RPC. They are read-ily produced from raw materials, which are available in virtually unlimited supply (Ref 1). The freshest, thinnest fibers are the strongest because the thinner fibers are more ductile. 1. Mechanical properties of Glass. Density. The density of glass is 2.5, which gives flat glass a mass of 2.5kg per m2 per mm of thickness, or 2500 kg per m3. Compressive strength. The compressive strength of glass is extremely high: 1000 N/mm2 = 1000 MPa. This means that to shatter a 1cm cube of glass, it requires a load of some 10 tonnes. The injection method is common in the production of randomly directed long (ranging from 5 to 25 mm) and short (less than 3 mm) fiber-reinforced composites. Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high-temperature tolerance, and low thermal expansion. Polybenzimidazole (PBI, short for poly[2,2-(m-phenylen)-5,5-bisbenzimidazole]) fiber is a synthetic fiber with a very high decomposition temperature.
