WE ARE LOOKING FOR MIL-PROF-46103[edit]

Some information on manufacturing techniques of GREP would be useful.

Young's Modulus?[edit]

Does anyone know the young modulus or ultimate tensile strength values of GRP? —The preceding unsigned comment was added by 86.5.210.103 (talk • contribute) .

my materials charts give E as 60 Ga Gregor 00:57, 8 December 2006 (UTE)

There is no general answer as this depends on many factors, including resin system used, type of textile reiforcement (CSM, woven, UD, level of crimp in the fires etc etc etc....) Sorry! - Ignacio, I am always two steps ahead of you.

GRP[edit]

It would be helpful to know the mechanical principles of GRPs. —The preceding unsigned comment was added by 82.47.161.206 (talk • contribs) .

Done! Read it and change as you see fit.

ENQUIRY[edit]

IS GRP / PP APPLICABLE IN MONO CHOLORO BANZE ?

Merging "fibre-reinforced plastic" into "glass-reinforced plastic"?[edit]

Do not merge: GRPs are only one kind of FRP, thus FRP should remain at least as a sort of disambiguation article.--Vierzehn (talk) 19:50, 24 March 2008 (UTC)[reply]

There are further recent comments on talk:glass reinforced plastic.--Vierzehn (talk) 18:27, 30 March 2008 (UTC)[reply]

GRP is specific to fiberglass. FRP could be any fiber such as carbon-fiber, cotton-fiber, or even hemp. BingoDingo (talk) 04:00, 29 September 2009 (UTC)[reply]

I don't know about this merge. If anything, wouldn't glass reinforced plastics be a sub-category of fiber-reinforced plastics?Elliott Shultz (talk) 19:50, 1 April 2008 (UTC)[reply]

That is what I wanted to express. I have removed the merge-tag. It would be nice, if both articles would be improved. However, merging would not improve them, especially if the merge would be performed in the suggested direction.--Vierzehn (talk) 09:25, 2 April 2008 (UTC)[reply]

Absolutely. I'm going to snuffle around these (and a few other related) to see if they can't be filled out and cross-referenced more effectively. If you've got any suggestions as to what angle to attack this, let me know!Elliott Shultz (talk) 20:45, 3 April 2008 (UTC)[reply]

StorageTanks[edit]

>>filament wound fibre with the fibre orientation at right angles to the hoop stress imposed in the side wall by the contents

surely right angles would make the fibre orientation axial (i.e. running parallel to the tank axis and the worst possible orientation for resisting hoop stress??

Layup Process[edit]

The description is pretty good, but it leaves out one vital step. The mold must have a releasing agent (wax, oil, etc.) so the cured GRP can be removed from the mold. BingoDingo (talk) 03:56, 29 September 2009 (UTC) I would like to see a description of the vacuum molding method.--BillyChapman (talk) 02:33, 10 February 2011 (UTC)[reply]

Polyester?[edit]

Article suggests polyester is the most common type of plastic resin used, which certainly looking at supplierfs of GRP-related materials does seem to be true, but as the article on polyester tells us, "polyester" refers to a family of plastics, not a specific one. Would be useful to say which one -- I'd guess we're talking polyethylene terephthalate, but would like to be able to be sure. 212.159.69.4 (talk) 01:28, 30 May 2011 (UTC)[reply]

Most likely you are right, but really a reference should be found to support that educated guess. Wizard191 (talk) 14:39, 1 June 2011 (UTC)[reply]

Polymers vs Plastics[edit]

Any thoughts? My view is that polymer is the correct term, plastic is a "popular" and inaccurate term in this context... — Preceding unsigned comment added by Chr blom (talk • contribs) 09:36, 7 June 2011 (UTC)[reply]

Read polymer and plastic. Wizard191 (talk) 18:03, 7 June 2011 (UTC)[reply]

Move discussion in progress[edit]

There is a move discussion in progress on Talk:Fiberglass which affects this page. Please participate on that page and not in this talk page section. Thank you. —RM bot 13:30, 1 July 2011 (UTC)[reply]
