What are the physical properties of Prepreg Carbon Fibre that make it particularly suitable for wheels?

0

Some of the properties of Carbon Fibre composites as used in BST wheels. Material used – Carbon Fibre Prepreg in a woven and unidirectional format, embedded in a resin matrix, made from toughened epoxy. – Max structural temperature: 120 degrees C – Min structural temperature: -40 degrees C – Corrosion resistance: Totally corrosion free – Chemical resistance: Resistant to most dilutants such as acetone, benzene, thinners, – Automotive fluid resistance: Limited resistance to brake fluids and acids – Density: Approximately 1.7 kg/qdm (Aluminium 2.7, Titanium 4.5, Steel 7.9) – Damage Tolerance: Similar to 2024 Aluminium – Strength: Better than 2024 Aluminium – Stiffness: Similar to 2024 Aluminium Variable wall thicknesses can be created anywhere as needed in order to increase strength where required. Fibres are oriented in the direction of stress in order to increase strength.
