Materials. The composite material consisted of unidirectional (UD) carbon fibre-reinforced PPS (TC1100, Toray Advanced Composites). The laminates were composed of 16 UD plies stacked in a quasi-isotropic lay-up [0/90/±45]2S. They were compression-moulded in a hot press to 254 x 254 mm² laminates. The temperature was increased to approximately 320°C under a 0.17 MPa contact pressure. The pressure was then increased to 0.7 MPa and held for 20 minutes. The material was then cooled down until it reached a temperature of approximately 50°C. The average heating and cooling rates were 10°C/minute and 30°C/minute, respectively. The final thickness of the laminates was 3.3 mm. The laminates were then cut using a diamond saw to 101.6 mm x 25.4 mm coupons. The HE was a 304 SS plain weave mesh with an opening gap width of 90 μm and a 40 μm wire diameter.
Materials. The use of titanium in the construction of the frame, the front forks, the handlebars, the swing arms, the swing arm spindles and the wheel spindles is forbidden. For wheel spindles, the use of light alloys is also forbidden. The use of titanium alloy nuts and bolts is allowed.
