The effect of the boundary interphase on the thermomechanical behaviour of composites reinforced with short fibres

摘要: Abstract Glass-resin composites may be considered in reality to a multiphase system, since they incorporate not only the two main phases, but also ‘interphase’, which is an area between fibre and matrix containing both areas of adsorption interaction polymer surface layers into glass fibres, as well mechanical imperfections. The concept boundary interphase, thermomechanical properties this interphase metal-filled epoxies was investigated previous studies by authors.1,2 It proved that material viscoelastic one with different thermal properties. Furthermore it found that, temperature composite changing, has dramatic effect on overall behaviour composite, due thermomechanical, interphase. On other hand, interphase-volume fraction criterion quality adhesion filler. In paper, mechanism load transfer across interface case reinforced short theoretically. order explain effect, model similar Rosen's some modifications used.
