FIBREGLASS

A fibre-reinforced polymer made of a plastic matrix reinforced by fine glass fibres. An individual structural glass fiber is both stiff and strong in tension and compression. If a collection of fibers can be arranged permanently in a preferred direction within a material, and if the fibers can be prevented from buckling in compression, then that material will become preferentially strong in that direction. By laying multiple layers of fiber on top of one another, with each layer oriented in various preferred directions, the stiffness and strength properties of the overall material can be controlled in an efficient manner.

POLYURETHANE

A synthetic material frequently used as an alternative to leather in the manufacturing of footwear. PU is light, flexible and durable.

ALUMINUM

A low-density and corrosion-resistant metal with good durability and conductivity properties.
