AS Physics Unit 11 Materials – Further Reading Mr D Powell
Mr Powell 2009 Index How do materials behave? This image show a broken section taken from the edge of the tennis racquet. You should be able to see the carbon fibres and how many have been pulled out of the surface. In between the fibres it is possible to see some of the fractured epoxy resin. This image shows the cell-like structure of the material which enables it to be compressed by small stresses.
Mr Powell 2009 Index How do materials behave? This image shows a classic brittle failure in a metal. You can see small flat cleavage facets which will reflect the light, giving the surface a shiny appearance. The size of the facets can be taken as approximately equal to the grain size of the material. This image shows a classic ductile failure in a metal, with voids around particles being evident.
