Developing Structure-Property Linkage for Glass Fibre Reinforced Polymer Composites
Presented by

Prof. Surya Kalidindi
Dr. Tony Fast
Background
• Forming processes create varied
and complex microstructures
• Microstructure varies even within a
simple part such as this plate
• Understanding the complexity of
these microstructures is an open
field which can give insight to the
properties of these materials

Motivation
• The structure and organization of the
reinforcement greatly affect the final
properties of the part
• Conventional approaches to property
determination do not take into account
the microstructure of the reinforcement
• Voigt model [4]
• Ruess Model [5]
• Those that do are based on a assumed
configurations of the fibres, not the
actual microstructure [6]Figure 5: Complex microstructure of FRPC.
