Abstract
The anisotropic mechanical properties of fibre reinforced composites are – by definition – dependent upon the orientation of fibres within the material. Most calculations assume that fibres in a so-called “unidirectinal” composite are straight. However even the naked eye can see that bundles of fibres (tows) are not straight, but exhibit non-uniform “waviness”. This talk will present work in progress to characterise the orientation of fibres in 2 and 3 dimensions, and to determine the effect of these waviness defects upon material properties, and compressive strength in particular.
Series This talk is part of the Engineering - Mechanics and Materials Seminar Series series.
