Abstract:
Ultra-thin woven fibre composites are becoming
popular in a wide range of weight-sensitive applications and
hence it is important to predict their mechanical properties for
accurate analysis and design purposes. This paper presents a
parametric study on the homogenized response of two-ply plain
woven carbon fibre composites. Influence of volume fractions,
traction coefficients and fibre/resin material parameters on the
laminate stiffness matrix (ABD) entries were investigated. For
this study, a parametric representative unit cell is generated
using a finite element pre-processor, TexGen and a Matlab
based algorithm. An automated algorithmic computation of the
laminate stiffness matrix is used to study its variations for
different combinations of uncertain parameters. Such
variations are compared with the experimental results to learn
the possible reasons for the observed deviations between
experimental and numerical results. It is shown that the volume
fractions linearly scale the laminate stiffness entries, though
interestingly, each entry has a unique scaling factor.
