In my book a tub is sure some square inches of cloth and honeycomb but the main issue must be labour ...assuming a guy is worth 80or so € per hour you are claiming they need 6000 or something hours to lay up a tub? in other words ,to get a tub ready in 6 weeks that is 12 guys working flatout 7 days a week
12 hours per day..sorry don´t buy that.Somethings wrong in this calculation.
i believe 600 to 1000hours is a possibility all things counted...but the cost is not just stemming from material and labour to produce the actual bit ...the real work has gone into producing the molds .
I think there's something like 300-500 layers for the tub. Not exactly an easy job.
That includes labour, materials, mould production and associated costs like running the autoclaves. The only area it dosnt touch is R&D costs. The fact that many of the top teams now use a single mould production technique (Lotus does i know that) that increases the production cost as the mould is harder to produce.
The only teams that use a twin mould production are, Force India, Caterham, Marussia and Hispania. The twin mould method decreases cost by arround 40%, but also provides less stiffness in the chassis, however the stifness strength is virtually minamal, theres something like 1% in it, but 1% is worth something like 10% extra torques or something when the power of the engine gets transmitted to the track. The single mould method seemingly gives a car an extra 3 to 4 meters extra traction off of a corner, whitch over a track with an average 8 slow to medium speed corners is 32 meters extra, whitch is effectivly a tenth and a half extra pace for a little extra effort and cost.
Its a trade off in effect, the smaller teams cant afford a single mould so go for a twin mould due to cost and time constraints, but as more teams use it, costs will come down, however thats down to how complex the tub structures become as the R&D guys are always looking at carbon lay up methods and as theese become more advanced, costs will rise still futher. And i doubt the FIA will get into how the teams produce a chassis any time soon.
Just for comparison, a open topped LMP1 can cost €850,000 and a enclosed version now generally costs €1.1m plus. Audis cars last year cost a reported €1.35m a chassis last year, and McNish and Rockenfeller have 2 chassis to thank for their life. However a LMP1 chassis has to be built to have a life span of arround 70,000km, a F1 chassis generally has a life span of arround 11,500km, however many chassis do much more than this, but it isnt the case now post in season testing ban, many chassis pre in season testing ban could do 15,000km. easily. F1 chassis problems can be delt with easily, LMP chassis arnt as easy to fix.
