Q&A Community Guidelines

Asking a question


Provide a one-line summary, phrased as a question. For example, “What is areal weight?” or “What manufacturing process is suitable for producing low-volume composite parts?”

Question Description

Use the description to give some more detail about your question and what you’re trying to achieve. Ensure your question relates to composite materials, their manufacturing, processing and application.

Please only ask questions that can be answered, not just discussed. Keep questions short and simple with sufficient detail to enable someone to answer, sharing your research.


To enable users to find relevant content, news stories, events, jobs and questions is categorised. Provide at least one tag to describe your question.

For a full list of tags, see our categories page.

Answering a question

Review the question and provide a detailed, well researched answer. Try to answer with facts and not opinion.

Answers should be original – do not plagiarise content from other sites.

Actually answer the question. Links to external sites are welcome, but an answer with nothing more than a link doesn’t help our users, especially if that link becomes broken in the future.

Questions can have multiple answers and the one with the most upvotes will appear at the top of the list.

Editing other users’ questions and answers

Users with sufficient reputation will be able to edit other users’ questions and answers. Do this to improve the clarity of what’s being asked or answered to for other users of this site.

Voting on questions and answers

Users with sufficient reputation (see list below) can upvote and downvote questions and answers. You can only vote once each per question and answer and votes can’t be revoked once cast.

  • Upvote questions/answers which you think are useful, well-written and researched.
  • Downvote questions which you think aren’t useful or are asking opinion (such as “Is X better than Y?”).
  • Downvote answers which don’t answer the question or don’t provide sufficient detail.


Use the comments section to discuss further points (and give opinion) relating to the question and answers (like asking for clarification / more detail) which don’t necessarily fit as an answer.

General Points

Stay on-topic

Ensure your question relates to composite materials.

No self-promotion

Links to your blog, website, services or products will almost always be removed.

Don’t Be a Jerk

Personal attacks and harassment will not be tolerated. Sexist, racist, misogynist, homophobic, and broad, offensive generalisations about groups of people are simply not allowed. Comments or discussions written intentionally to provoke will also be removed.
