The time-dependent, local microbuckling of fibers in polymer composites is modeled in the context of viscoelasticity. The instability or “growth-of-waviness”-type analysis is carried out for bifurcation (initially straight fibers), as well as for imperfection sensitivity (initially wavy fibers). The concept of dominant wavelength, previously defined for viscoelastic bifurcation by Biot, is generalized for viscoelastic imperfection sensitivity. A parametric study is presented to encompass a wide range of physically useful values to study the effects of matrix properties, fiber-matrix interfacial conditions, and time-dependent loads on dominant wavelengths. A marked difference is observed between the viscoelastic bifurcation and imperfection sensitivity dominant wavelength results. The bifurcation dominant wavelength is seen to depend negligibly on matrix properties, yet highly on the applied load and the interfacial conditions. On the other hand, the imperfection sensitive dominant wavelength is strongly dependent on matrix properties, while negligibly on load and interface conditions.

Damage initiation and progression in long fibre unidirectional continuous polymer composites has been studied at the micro-scale considering a three dimensional repeating unit cell (3D-RUC) with square packing consisting of a single fibre in a polymer matrix. Three damage modes under static loading have been looked at, viz., matrix damage, fibre failure and fibre-matrix debonding. A progressive damage model for the matrix, fibre breakage model using maximum stress failure criterion and interface debonding using a traction-separation criterion via cohesive zone modelling (CZM) approach has been implemented. Homogenization of the said 3D-RUC has been conducted for various load cases that describes the averaged response of the microstructure under combined progressive damage modes.
