SUMMARY:Fibre Waviness Defects in Composite Materials - Dr Stuart Lemanski
 \, CUED
DTSTART:20101015T130000Z
DTEND:20101015T140000Z
UID:TALK25977@talks.cam.ac.uk
CONTACT:Ms Helen Gardner
DESCRIPTION:The anisotropic mechanical properties of fibre reinforced comp
 osites are - by definition - dependent upon the orientation of fibres with
 in the material. Most calculations assume that fibres in a so-called "unid
 irectinal" composite are straight. However even the naked eye can see that
  bundles of fibres (tows) are not straight\, but exhibit non-uniform "wavi
 ness". This talk will present work in progress to characterise the orienta
 tion of fibres in 2 and 3 dimensions\, and to determine the effect of thes
 e waviness defects upon material properties\, and compressive strength in 
 particular.
