Transverse compression properties of composite reinforcements

P.A. Kelly,     The University of Auckland, New Zealand

Abstract:

This chapter discusses transverse compression, one of the dominant deformation modes arising in fibrous reinforcement materials during composites forming and manufacture. After a brief review of the experimental procedure to determine fabric compressibility, the standard compaction curve is introduced, together with associated numerical models. The chapter then discusses the distinctive inelastic properties and response of fibrous materials, including their viscoelasticity and plasticity. The concept of locked energy is introduced, and modelling strategies for its incorporation within a general thermomechanical ...
