What? Pyrolized or not?[edit]

I don't get it - how can a bunch of flax and resin compete with graphite, graphene, spectra, dynema, kevlar, etc? Am I missing something? Don't they pyrolyze it first? 2600:1700:4CA1:3C80:ED78:EA7D:6EE1:95DA (talk) 03:50, 29 June 2018 (UTC)[reply]

Some proposed changes[edit]

Processing[edit]

Biocomposites behave similarly to conventional plastics, making them viable alternatives for use in traditional manufacturing methods such as injection molding, extrusion or blow molding. As with processing any plastic, though, it’s important to consider the processing conditions required for biocomposites. General considerations when processing a biocomposite include pre-drying, melt temperature and shrink behavior.

Biocomposites readily absorb moisture from the environment, which is why drying in a desiccant dryer prior to processing is often recommended for these materials. Processing temperature for biocomposites should not exceed 400° Fahrenheit. Above that threshold, the cellulosic parts of the fillers and fibers risk burning, whereby the material can begin to discolor and degrade. In injection molding, increasing the size of runners and gates and decreasing injection speed can also help to alleviate the shear heat that can build up during the injection process. The natural fiber and fillers in a biocomposite also reduce the melt flow and shrink rate of the material. For example, polyethylene reinforced with wood fiber shrinks at a lower rate than pure polyethylene — and the higher the ratio of wood, the lower the melt flow and shrink rate of the composite.

Explanation of issue: This page gives a list of manufacturing methods biocomposites are suited for, but does not give a description of biocomposite-specific processing considerations.

  Unable to review edit request  
Your edit request could not be reviewed because the request is not formatted correctly.

  1. The citation style predominantly used by the Biocomposite article appears to be Citation Style 1. The citation style used in the edit request consists of bare URL's.[a] Any requested edit of yours which may be implemented will need to resemble the current style already in use in the article – in this case, CS1. (See WP:CITEVAR.)
  2. Citation ref tags have not been placed within the requested text indicating which portions of the text the source is referencing. (See WP:INTEGRITY.)

In the collapsed section below titled Request edit examples, I have illustrated two: The first shows how the edit request was submitted; the second shows how requests should be submitted in the future.

Request edit examples
Incorrectly formatted request:

The Sun's diameter is 864,337.3 miles, while the Moon's diameter is 2,159 miles. The Sun's temperature is 5,778 degrees Kelvin.

<ref>https://www.booksource.com</ref>
<ref>https://www.journalsource.com</ref>
<ref>https://www.websource.com</ref>

In the example above there are three URL's provided with the claim statements, but these URL's have not been placed using Citation Style 1, which is the style predominantly used by the Biocomposite article. Additionally, the ref tags have not been placed within the text at the exact positions where the information they reference resides. Using the correct style and the correct positioning of the ref tags, the WikiFormatted text would resemble the following:

Correctly formatted request:

Please add the following sentence to the first paragraph of the article's "Sun and Moon" section:

The Sun's diameter is 864,337.3 miles,<ref>{{cite book|last1=Sjöblad|first1=Tristan|title=The Sun|url=http://www.booksource.com|publisher=Academic Press|date=2018|page=1}}</ref> while the Moon's diameter is 2,159 miles.<ref>{{cite journal|last1=Duvalier|first1=Gabrielle|title=Size of the Moon|journal=Scientific American|issue=78|volume=51|url=http://www.journalsource.com|date=2018|page=46}}</ref> The Sun's temperature is 5,778 degrees Kelvin.<ref>{{cite book|last1=Uemura|first1=Shu|title=The Sun's Heat|url=http://www.websource.com|publisher=Academic Press|date=2018|page=2}}</ref>

Which displays as:

Please add the following sentence to the first paragraph of the article's "Sun and Moon" section:

  • The Sun's diameter is 864,337.3 miles,[1] while the Moon's diameter is 2,159 miles.[2] The Sun's temperature is 5,778 degrees Kelvin.[3]

In the example above the references have been formatted according to Citation Style 1, which shows the author, the source's name, date, etc. Also, the ref tags are placed in the exact location where the text which they reference resides. As Wikipedia is a volunteer project, edit requests such yours are generally expected to have this formatting done before the request is submitted for review.

Kindly rewrite your edit request so that it aligns more with the second example shown in the collapsed section above, and feel free to re-submit that edit request at your earliest convenience. If you have any questions about this formatting please don't hesitate to ask myself or another editor. Regards,  Spintendo  22:02, 26 November 2018 (UTC)[reply]

Notes

  1. ^ The use of bare URLs as references is a style which is acceptable for use in Wikipedia. However, general practice dictates that the style already in use for an article be the one that is subsequently used for all future additions unless changed by editorial consensus. (See WP:CITEVAR.)
