Why is the JMIA monocoque epoch-making?
It is because it is a monocoque made of pure CFRP.
It is not a alminium honeycomb sandwich manufacturing method.
The JMIA monocoque is manufactured by the method of wrapping CFRP prepreg around the mastering model.
The advantage and the fault of the JMIA monocoque are as follows.
(Advantage)
It is possible to manufacture it more cheaply and easily than the honeycomb sandwich manufacturing method.
Because the rigidity is uniform, pick-up point of the suspension can be freely decided.
It is easy to change to the best rigidity for each category by changing the number of sheets of CFRP prepreg.
Because it is not bonded to the honeycomb, the rigidity is not deteriorated.
(Fault)
It is heavier than the honeycomb monocoque.
It is Dome to manufacture the JMIA monocoque.
They will promote the sales of the JMIA monocoque to a variety of single seater categories for which the CFRP monocoque is not used.
Dome will return to Le Mans if their businesses succeed.
