Carbon fibre composites benefit latest BMW

Hexcel’s CFRP technology is being used in the BMW 7 Series to save weight and reinforce the metal shell of the B-pillar. Hexcel has supplied BMW with preforms made of unidirectional carbon prepreg set in various orientations and combined with adhesive. The prepreg is made from Hexcel’s HexPly M77 resin system that cures in one and a half minutes at 160°C.

To meet the requirements for series production in the automotive industry, Hexcel has installed a fully automated production line in Austria that converts unidirectional prepreg into bidirectional preforms. The process allows prepreg plies of different weights and orientation to be combined in the same ply-book and includes automated cutting, camera-assisted ply positioning, and integration of adhesive and automated packing.

This fully-automated production cell makes B-pillar preforms for up to 500 cars each day allowing Hexcel to meet the high production rates required by automotive manufacturers and the high quality expectations of premium car manufacturers.

Hexcel’s CFRP solutions are used in standalone and hybrid applications to help not only lighten cars which contributes to overall CO2 reductions, but also help to improve performance and safety through increased strength and durability.

Dear Sir,

It is with much interest that I read your article in the Engineering Materials site. The reason for commenting is that whilst you may believe from my e-mail 'Airbus.com' I work for Airbus (Yes I do and a long standing time within the Aerospace industry), I work within the world of Non Destructive testing (NDT). I'm enquiring as to what process BMW have evolved (that they can share) for the Quality Assurance / Control they have within their production environment. I work (as I said) for an Airbus Group company called Testia Ltd. (which is part of a global network), within Testia's portfolio we include NDT inspection services, NDT Training and Qualification of personnel. So should you have any requirements or questions, please ask.

I look forward to hearing from you.

Kind Regards,

Keith Phillips
Chief Operations Officer
Testia Ltd.
