DEVELOPMENT OF MODIFIED POLYMER COMPOSITES FOR REPAIR PARTS OF TRANSPORT POWER PLANTS
Abstract
The paper studied the effect of modifying the content of benzene-1,3-diamine in the physical and mechanical properties and structure of the modified epoxy composites based on ED-20 epoxy resin bisphenol. An analysis of the data selected optimum additive concentration at which values provide optimum toughness, and stress destroying the flexural modulus composite materials developed. In order to confirm the validity of the results of the study of physical and mechanical properties of composites further analyzed the structure of fracture surface materials. Analysis fraktogramm original epoxy matrix suggests the formation of a fracture surface of the branched lines chipping and organized factions with a layered structure with the subsequent changes depending on the content of the modifier. Wherein the cleaving line in some cases, have pronounced grooves that characterize the stress state of the material and its fragility.
