Microscale Analysis of Virtually Cured Polymer Matrix Composites Accounting for Uncertainty in Matrix Properties During Manufacturing

SAGAR SHAH, MARIANNA MAIARU

Abstract


This paper proposes a study on mechanical properties of virtually cured microstructures accounting for uncertainty in matrix properties and fiber packing. Computations are carried out using the finite element method (FEM) using the commercial code Abaqus supplemented by user written subroutines. An instantaneous linear elastic model for the stress evolution during manufacturing is employed to model curing. Results are presented in terms of transverse stiffness and strength for cured microstructures of different sizes. Comparisons are proposed with models not including curing induced residual stresses.
