French term or phrase: drapage

This is in a document concerning a company manufacturing carbon masts. The process is described as follows: “l’opération consiste à disposer les tissus carbone pré-imprégnés de résine dans les moules femelles”

I had used "covering" elsewhere in the document, but am now doubting this. I'm looking for the right manufacturing terminology.

Apart from the above sentence, the term appears only in headings. There is also a "plan de drapage" and a "chef de drapage".

When draping the fabric over vertical areas and large curvatures of the component – for instance the hull – many of our customers favour the patented, self-adhesive SAERfix fabric, which makes this work easier.

Early hulls were made by draping the reinforcement over a pattern or former made of wood (male mould) and painting on the resin.

Grading comment

Very grateful for all your help in this. Right towards the end of the translation I stumbled upon a video presentation of the process (same company) which displayed the title in English as "Laminating". So in the end I have gone with laminating, even if technically it may not be 100% accurate!

Asker: Thanks, Ana. I believe this is the term I'm looking for. Great!

drapability

Finally, the fibres and the stitching pattern were customised for best drapability and optimum resin flow during the infusion process.

Excellent handling and drapability up to 35°C / 95°F

Asker: Thanks, Wendy. In my context I'm looking for a word to describe the process, so while your suggestion backs up what Ana has suggested, I believe the term I need is 'draping' rather than 'drapability'.

5 hrs confidence:

plan de drapage = stacking sequence stacking sequence

Explanation:
"Drapage ... consiste à déposer sur un modèle (ou moule) des nappes prédécoupées de tissus de fibres préimprégnées et à polymériser la structure selon un cycle de cuisson bien défini en autoclave.... le principal avantage de ce procédé est de pouvoir déposer les fibres dans le sens des efforts que devra supporter la pièce".

""Drape" et "drapability" traduisent l'aptitude au drapage":

"drape : the ability of a prepreg to conform to the shape of a contour surface"
Glossary of advanced composites terms. Advanced Composites, 1992, Bluebook, page 22.
"Prepregs manufactured with epoxy resin matrices poses good drapability and excellent tack".
Design with advanced composite materials, Leslie N Philipps, 1989, page 106.

Individual plies (nappes/plis) are stacked in approrpiate fiber orientation and sequence.

Drapage can be translated in a number of ways. Here are my suggestions:

plan de drapage : stacking sequence
chef de drapage = ??? If this is the person in charge of "drapage" it could be the "lay-up technicain" or the "wrapping technician".

"drapage" alone can be translated as : drapability, wrapping, dry lay-up or stacking sequence.

It depends how it is being used.

You questions actually is a two-in-one question. ;-)

A stacking sequence describes the ply order in a laminate. It is also described more commenly as "lay-up". "Lay-up" and "stacking sequence" are described generally by "stratification". A composite piece is "stratifiée".

So, for "plan de drapage" , I'd go with "lay-up" or "stacking sequence".
For "Chef de drapage", I'd go with 'lay-up technician".

The work provides a word for word index, but you then have to start rooting around for terms in the original language extracts from articles, professional publications and so on used as reference sources.

If you do a fair bit or nautical construction (or aircraft construction) then this expenseive work would be worth the investment!

The dictionary is in fact a collection of extracts from original language texts compared face to face and from which you can make up your own mind about terminology based on the piece you are working on.

The term you post for the glossary can be translated in a number of ways but the terms you actually appear to be seeking are no doubt more specific.

HTH.

lay-up

Explanation:
The lay-up technology is based on the implementation of fibers fabrics (glass, aramid, carbon, …) first impregnated with a resin (epoxy, phenolic,…).
