8 Sep 2001: Overview. Prototyping is the making of a test component before full manufacture begins.

8 Sep 2001: Economics. Production rate is limited by the insertion and removal of the blank, so some form of automation is often used.

8 Sep 2001: Some scrap is always produced and cannot be directly recycled. Economics.

8 Sep 2001: Economics. If possible, avoid cutting! A surprising number of designs involve a cutting process followed by a joining process.

8 Sep 2001: Economics. Basic equipment costs around £10,000, but automation can increase this significantly.

7 Sep 2001: it is the same whatever the size of the test-piece. Many applications require stiff materials, e.g.

8 Sep 2001: cured). Economics. There are few composite forming processes, and the decision of which to use is normally determined first by shape and type of fibre (chopped or continuous), and then by

8 Sep 2001: As a result, a self-quench is usually sufficient. The equipment is very expensive and not economic for large surfaces, but automation is straightforward and very precise control can be achieved.

7 Sep 2001: Young's modulus measures stiffness and is a material constant, i.e. it is the same whatever the size of the test-piece.

5 Sep 2001: important and could be assessed by a tensile test to measure elastic deformation before failure. ... supported beam of the test material (un-notched, or notched underneath on the tensile edge) – by.
