Fatigue[edit]

There's now one mention that CFRP is preferred to Al because of better fatigue life. But I would imagine that that is not true of just any CFRP, but rather only ones that are carefully selected for applications where that is a concern. I think it would be great if someone more knowledgeable than I were to add more extensive, referenced discussion of fatigue to this article. Thanks!! Ccrrccrr (talk) 13:06, 26 October 2009 (UTC)

In addition, I don't believe aluminum has a fatigue limit (see Callister "Materials Science and Engineering: 5th Ed. p 211). Perhaps the author was thinking of steel. —Preceding unsigned comment added by 129.238.237.96 (talk) 17:12, 10 November 2009 (UTC)

Aluminum and its alloys do have a fatigue endurance limit -- see, for example, the following link.

Any detailed fatigue life comparison would be very application specific. Alloy selection, geometry, fiber direction and resin system would swamp the discussion. It is probably best to stick to the general case. 199.46.198.230 (talk) 18:02, 7 October 2014 (UTC)

Production[edit]

Should contain production like how it is produced.115.241.241.2d (talk) 10:43, 4 May 2014 (UTC)

Properties[edit]

Not being a materials scientist, I don't want to change the page directly, but the given formula for elastic modulus of the composite with the fibers oriented transverse to the applied load appears to have an important typo. It's given as: This fails simple sniff tests like V_m=1 -> E_m=E_c and V_f=1 -> Ec=E_f. More likely it should be: This would match the equation I see stated elsewhere, such as http://web.mit.edu/3.082/www/team2_f01/background.html.

Hello fellow Wikipedians,

I have just added archive links to 2 external links on Carbon-fiber-reinforced polymer. Please take a moment to review my edit. You may add {{cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

You may set the |checked=, on this template, to true or failed to let other editors know you reviewed the change. If you find any errors, please use the tools below to fix them or call an editor by setting |needhelp= to your help request.

  • If you have discovered URLs which were erroneously considered dead by the bot, you can report them with this tool.
  • If you found an error with any archives or the URLs themselves, you can fix them with this tool.

If you are unable to use these tools, you may set |needhelp=<your help request> on this template to request help from an experienced user. Please include details about your problem, to help other editors.
