The role of matrix ductility on the toughenability and toughening mechanism of elastomermodified, diglycidyl ether of bisphenol A (DGEBA)-based epoxies is investigated. Matrix ductility is varied by using epoxide resins of varying epoxide monomer molecular weights. These epoxide resins are cured using 4,4' diaminodiphenyl sulphone (DDS) and, in some cases, modified with 10vol % carboxyl-termina...

Abstract We consider the problem of learning structures and parameters continuous-time Bayesian networks (CTBNs) from time-course data under minimal experimental resources. In practice, cost generating poses a bottleneck, especially in natural social sciences. A popular approach to overcome this is optimal design (BOED). However, BOED becomes infeasible high-dimensional settings, as it involves...

The degradation of the epoxy system was studied for the prepared six blend samples with the incorporation of 0 wt% 25 wt% carboxyl terminated butadiene acrylonitrile (CTBN) copolymer, on a dynamic basis using Thermo gravimetric analysis (TGA) technique under a nitrogen atmosphere. The blends were prepared by physical mixing and were cured with diamine. The degradation of each sample followed se...

Abstract The addition of well-dispersed nanoparticles can significantly increase the mechanical properties and toughness epoxy polymers. In this study, an resin was modified by silica nanoparticles, (CTBN) rubber microparticles a combination both. An in-situ orthogonal cutting rig combined with high magnification high-speed imaging system used to determine effects on chip formation mechanism ma...
