5 THINGS YOU NEED TO KNOW
The frames are produced using Resin Transfer Molding (RTM). The production time is only a few hours and when the parts leave the mould they are ready to go, like an aluminium part. This differs from a handmade carbon fibre alternative, which would take days to produce.
You can modify the stiffness by changing the characteristics of the fibre, the directions of the fibre, the material thickness or the geometry of the frame. You can design a carbon frame to be softer in some directions if needed without breaking it.
A carbon frame is much stronger than a traditional aluminium chassis, in fact in strength terms it’s much closer to steel. In the case of a hard crash, the frame will not break completely and you will be able to see deformed areas. However, the attached components, like handlebars, fork and footpegs, should fail long before the frame gets any sort of structural damage.
The new carbon fibre frame of the BMW HP4 Race has been designed to withstand the same heat as the conventional aluminium chassis as used on the BMW S1000RR. As the frame is formed using a two-stage tempering process, it means it could withstand 100 degrees centigrade for a continuous 10-year test with no change to the structure.
Weight loss 5
Weight loss through a carbon-fibre frame depends entirely on the bike it has been applied to, however in the case of BMW’S HP4 Race the difference is significant. At the moment, we cannot reveal any more than that, but we are very excited at the prospect of the performance and handling benefits riders will be able to experience when they ride the HP4 Race later this year.
