Nanoscale characterisation of thickness and properties of interphase in polymer matrix composites

摘要: An overview is presented of the properties and effective thickness interphase formed between fibres polymer matrices. Chemical physical characterization discussed to portray molecular interactions comprising layers in silane-treated glass-fibre composites. The gap physico-chemical investigation on one side bulk material testing other bridged by implementation novel techniques, such as nanoindentation, nanoscratch tests, atomic force microscopy (AFM), which have been successfully used for nanoscopic past few years. Salient differences are identified major findings these studies terms hardness/modulus relative matrix material. While there a significant "fibre stiffening" effect that may cause misinterpretation hardness very close fibre, formation both softer harder possible, d...
