Critical parameters in designing segmented polyurethanes and their effect on morphology and properties: A comprehensive review
TL;DR: In this paper, a comprehensive discussion is provided of the critical physical, chemical and structural parameters, such as soft and hard segment structures and their molecular weights, polymer composition, solubility parameters, competitive intermolecular interactions and others, which strongly affect the morphology and bulk and surface properties of segmented thermoplastic polyurethanes.

Silicone containing copolymers: Synthesis, properties and applications
Emel Yilgor,Iskender Yilgor +1 more
TL;DR: A comprehensive survey of the recent developments on the synthesis, properties and applications of silicone containing copolymers is provided in this paper, where the effect of silicone oligomer and organic segment structure and molecular weight on the morphology and surface and bulk properties of the resultant silicone containing polymeric network structures is also discussed.

A review of dendritic hyperbranched polymer as modifiers in epoxy composites
TL;DR: In this paper, both fully soluble and phase-separating epoxy-functionalised hyperbranched polymers were used, the latter showing more efficient toughening properties, but a close control of the phase separation mechanism was required, in order to avoid filtering effects before or during fibre impregnation.
Journal ArticleDOI
Thermoplastic-toughened epoxy polymers
TL;DR: In this paper, the microstructure and properties of two epoxy-resin systems which have been modified with varying amounts of a thermoplastic to improve the toughness of the thermosetting epoxy polymers, have been studied.

Deformation and fracture behaviour of a rubber-toughened epoxy: 1. Microstructure and fracture studies
TL;DR: In this article, the microstructure and fracture behavior of an unmodified and a rubber-modified epoxy have been studied and the mechanisms for this increased toughness have been considered and a mechanism that accounts for all the observed characteristics has been proposed.
Journal ArticleDOI
The interaction of a crack front with a second-phase dispersion
TL;DR: In this paper, it was shown that a crack front increases its length by changing its shape when it interacts with two or more inhomogeneities in a brittle material, and an expression for the fracture energy was obtained.
Journal ArticleDOI
Phase separation in epoxy resins containing polyethersulphone
TL;DR: In this paper, the phase separation of dissolved polyethersulphone (PES) from trifunctional and tetrafunctional epoxy resins during curing was studied using electron microscopy and dynamic mechanical spectroscopy.
Journal ArticleDOI
A model for the toughness of epoxy-rubber particulate composites
TL;DR: In this article, a new analytical model for toughening of epoxy-rubber composites is proposed, which predicts the failure strain of the particles in terms of their size and the amount of elastic energy stored in the rubber during stretching.

Fracture energy of an epoxy composite system
F. F. Lange,K. C. Radford +1 more
TL;DR: In this paper, the authors presented fracture energy data for an epoxy-alumina trihydrate composite system in which both the volume fraction and particle size of the dispersion were changed.
