Lotus E21 construction report part 4.1

Lamination Process has started

Now it’s going to get really interesting. I try as hard as possible, to get the direction and types of the fibres as close as possible to the original. From the inside of the monocoque I have understandably no information about fibre types and directions. But basically in F1 they use three types of fibres: Plain/Basket, Twill and Satin. For Plain and Twill I found some good templates on Google, the Satin I did more or less by myself. Later on I will also have to rescale the textures, because, they use quite big mesh sizes on Plain types especially on the underbody. The direction of the fibres in the cockpit entry area, I can figure out from pictures. Inside the monocoque, I guess they will use mainly quasiisotrop laminate lay-up. So I will mainly use 90° Twill and a bit of Satin on some areas. The side impact Zylon fibres you will not see as they are somewhere under the CFRP fibres.

If somebody does not come to terms with this whole composite stuff, just email me.

My name is Paul Bischof. I’m a student in mechanical engineering at the Technical University of Graz in Austria, expected finishing in February 2016. Since I was eight years old, I am building model planes out of paperboard. Since 2004 I scratch (that means building without an assembling set) Formula 1 and sportscars in 1:10th scale. The average time I need for such a car is around 400 to 700 hours within 4 to 8 months. One car has around 3500 up to 5000 single components. On this blog, you can take a look on my work and later, after my studies, hopefully you can see me in Formula 1.
