An attempt is made in this paper to give a qualitative interpretation to the experimental observations of the re-pull force which has been presented in Part 1. A mechanistic model is established which assumes that a pultruded composite component, which is not fully cured, will experience a creeping expansion due to the de-compaction of fiber reinforcement in the release zone. It is shown that such expansion, under certain conditions, may overwhelm the effect of resin shrinkage, and cause a considerable contribution to the pull force. Thus, the model established in this paper is expected to characterize, at least partially, the relevant mechanisms behind the pull force.
