Powdered compounds of mineral origin. 1 of 33 How have glass fibres been reinforced? With polyester 2 of 33 How are glass fibres kept pliable? By being painted with silicon. 3 of 33 What are the positives about glass fibres? Durable, strong, shatterproof, heat and old resistant, good electrical properties, non-stick, non-toxic. 4 of 33 What are negative surrounding the use of glass fibres? Poor abrasion resistance,requires a surface finish to reduce skin irritation. 5 of 33 What are glass fibres used for? Aerospace and military industries, flame and heat barriers, roof coverings, sterile hospital wall coverings, outerwear protective garments. 6 of 33 Describe the care requirements of glass fibres Machine washable, can bleach, can be dry-cleaned, can be tumbled-dryed. 7 of 33 Describe what fibre glass is made of? Fine fibres of glass. 8 of 33 What is fibre glass used as? Used as an insulation material, a strengthening product and for flame retardant fabrics. 9 of 33 How are carbon fibres made? By burning acrylic to produce carbon. 10 of 33 What has carbon fibre been made to replace? Used to replace metals. 11 of 33 What are the positives surrounding carbon fibres? Very strong, lightweight, abrasion resistant, flame retardant, resistant to chemicals, lightweight. 12 of 33 What are the negatives about carbon fibres? They are a non-renewable source, expensive. 13 of 33 Describe the end uses of carbon fibres Transport, upholstery, civil engineering, aerospace, sports products, protective clothing for emergency services. 14 of 33 Explain the aftercare required for carbon fibres Machine washable, can bleach, can be dry-cleaned and tumble dried. 15 of 33 What are graphite fibres? Extremely thin, composed of mostly carbon atoms. 16 of 33 How do the carbon atoms become a yarn? Atoms bonded together in crystals. Fibres are twisted together to form a yarn. 17 of 33 What is mostly used for metallic fibres? Aluminium, copper and steel. 18 of 33 What is used for more expensive uses? Silver and gold. 19 of 33 How is a metallic yarn produced? Thin sheet of metal cut in strips or fine wire. Metal thread spun around yarn. 20 of 33 What has been recently used? Lurex (metallised, polyester yarn) coated with fine plastic to prevent tarnishing. 21 of 33 What are the positives of using metallic fibres? Strong, lightweight, abrasion resistant, conductive, anti-static, protective 22 of 33 What are the end uses of metallic fibres? Decorative textiles, active sportswear, work wear, medical end uses. 23 of 33 Describe the after care required for metallic fibres Can be washed and tumble dried. 24 of 33 What are ceramic fibres made of? Powdered compounds of metal oxide, meta carbide, metal nitride or their mixtures. 25 of 33 What can ceramics content fibres regulate? Can regulate body temperature - warmer in cold temperatures, colder in warm. 26 of 33 What are the positives of ceramic fibres Provides UV protection, good insulation, good insulation, lightweight, low thermal conductivity, resistant to chemicals. 27 of 33 What are the end uses of ceramic fibres? Swimwear, UV protective clothing, industrial work wear, electrical, thermal and sound insulation. 28 of 33 Describe the aftercare required for ceramic fibres Machine washable, can bleach, can be dry-cleaned and tumble dried. 29 of 33 What temperatures can ceramics withstand? Up to 1000 degrees. 30 of 33 How can ceramics be incorporated into synthetic fibres? Either by coating them with ceramic particles or by encapsulating them within the fibre. 31 of 33 What are inorganic fibres made from? Mainly by inorganic chemicals based on natural elements. 32 of 33 Where are these materials for inorganic fibres found? Found in the Earth's crust. 33 of 33
