1. Read and translate the following text: fibres

Fibres are probably the oldest
engineering materials used by man. Jute, flax, and hemp have been
used for «engineered» products such as rope, cordage, nets,
water hose, and containers since antiquity. Other plant and animal
fibres have been used for felts, paper, brushes, and heavy structural
cloth.

The fibre industry is clearly
divided between natural fibres (from plant, animal, or mineral
sources) and synthetic fibres. Many synthetic fibres have been
developed specifically to replace natural fibres, because synthetics
often behave more predictably and are usually more uniform in size.

For engineering purposes,
glass, metallic, and organically derived synthetic fibres are most
significant. Nylon is used for belting, nets, hose, rope, parachutes,
webbing, ballistic cloths, and as reinforcement in tyres.

Metal fibres are used in
high-strength, high-temperature, light weight composite materials for
aerospace applications. Fibre composites improve the
strength-to-weight ratio of base materials such as titanium and
aluminium. Metal-fibre composites are used in turbine compressor
blades, heavy-duty bearings, pressure vessels and spacecraft re-entry
shields. Boron, carbon, graphite, and refractory oxide fibres are
common materials used in high-strength fibre composites.

Glass fibers are probably the
most common of all synthetic engineering fibers. These fibers are the
finest of all fibers, typically 1 to 4 microns in diameter. Glass
fibers are used for heat, sound, and electrical insulation; filters;
reinforcements for thermoplastics and thermoset resins and for rubber
(such as in tyres), fabrics; and fiber optics.
