You might be in for a bit of a shock ! The jobs and the work processes in aero and motorsport are night and day apart,more than you could ever imagine
Last year I was working at probably the largest private composites firm in the UK,mainly doing readbull but towards the end running the force India stuff and we had several guys come over from shorts in Belfast as they are all being laid off-they struggled like hell with motorsport to say the least
On facebook you have "laminators network" and "laminators r us" all the agencies host their jobs on there morsons,matchtec,vhr all sectors of the are covers and they are all very reluctant to switch people between sectors.
Lots of new stuff about even in the last couple of years,sooooo many parts made on 3d printed cores which is a whole art form in itself. Ply stacking and secondary machined wings,flexible but will pass the static load test ��,zylon intrusion panels- you don't know pain till you have done 6 plies of that into a matched mould,kevlar/dynema are so easy in comparison.suspension,try 3 different cloths per ply plus u/d staggering 2mm every layer over multiple faces.closed mould wrapped rohacell,mostly all aero winglets etc done this way and another art form in itself
There is so much stuff these days its ureal !

great write up rob! I can confirm that Aerospace and F1 are worlds apart from being in both and that there is a real skill shortage in all round technical skills, as rob pointed out most of the new laminators (myself included) get given a blue block tool to layup on following the plybook, cure it and then hand over to the trimmers.

Ive got a couple of mates running in the Mclaren endurance team this year and I knwo a couple of lads in WEC that do repairs and they are all trimmers that can do layup. The skill is in preparing the damage and then trying to get it back to looking what it was before.

Good luck to the OP its a great job and highly rewarding.

This is a fascinating subject. New production is interesting but repairs really require another skill set. It approaches art and I for one, would love to see more about this. Thanks guys for posting and please don't hesitate to show more.

the way I did it, in my garage from home

Repair to a Ferrari Challenge splitter.
make tool, repair core, make part from tool, co-bond piece inside vac bag with tool. wet layup





GTD 488 fender

make aluminum skin to fit with English wheel, make tool from skin, fab missing cascades, glue together. to keep the outer surface from being proud I use thin Textreme to tie in the splice
I'm sure there at many different ways to do it. It all gets wrapped in vinyl






this repair was easy compared to a MD-11 tailcone


my customer

How did you get the shape for the fender? I understand you made an aluminum tool but what did you use for that pattern? Great stuff!

Copy that! Like I said, more art than science.

sometimes you get the advantage of a replacement section.

a lot is done from scratch
