dcterms:description
Size, shape and material properties of the particles have a significant effect on the global behaviour of the composite. Generally, the addition of rigid particles to a polymeric matrix has an embrittling effect on the composite. Using very fine isometric filler of sub-micron range with proper surface treatment and good final dispersion enable to achieve enhancement of toughness without significant reduction of its stiffness. In the contribution the role of filler size and interphase properties on micro- and macro-behaviour of particulate composites is analysed from the experimental as well theoretical point of view. The main attention is focused on fracture toughness and stiffness values. The changes in stiffness was characterised by DMTA analysis on the macroscopic level and by pulse 1H-NMR (changes in crystallinity) and DSC analysis on microscopic level. Instrumented notched Charpy impact tests were used to estimate the fracture toughness.
