Mechanisms of toughening in rubber toughened polymers

Acta Metallurgica, 1986
Abstract A method is presented whereby various potential contributions to the toughness of rubber toughened polymers can be quantified. The tendencies toward either synergism or additivity amongst mechanisms is emphasised for rubber stretching, cavitation and shear banding. The method reveals that specific experimental measurements of microstructural

Effects of Annealing on Toughened and Non-Toughened Glass

Canadian Society of Forensic Science Journal, 1994
ABSTRACTThe effect of annealing on toughened and non-toughened glasses that have similar densities and refractive indices is examined with respect to the changes in density and refractive index after annealing. A correlation between the change in refractive index (ΔRI) and the change in density (Δδ) is drawn.

Polyurethane Toughened Polylactide *

Polymer Bulletin, 1998
Brittle polylactide (PLA) was toughened by introducing 5 wt % of a poly(ɛ-caprolactone)(PCL) diol- and triol-based polyurethane (PU) network. The extent of cross-linking of the PU was varied by changing the ratio between diol and triol. The effects of the PU content and its crosslink density on the mechanical properties and the toughness of PU/PLA ...

Mechanism of Toughening in Rubber Toughened Polyolefin—A Review

Polymer-Plastics Technology and Engineering, 2015
The recent advances and theories in the studies of the toughening mechanism have been reviewed to explain the effect of rubber particles in different rubber modified Polyolefin materials. To elucidate toughening effect, major theories e.g., critical particle distance, particle size, micro deformation by stress field of rubber, shear yielding and ...

Ceramics: Microstructural Toughening (Excluding Transformation Toughening, Whisker Toughening, and Continuous Fiber Toughening)

2001
The enhancement of fracture toughness in ceramic materials can occur over a broad range of length scales. The length scale that has received the greatest attention in structural ceramic materials is the microstructural scale, that of the grain dimensions that normally vary from 1 µm to 20 µm. In single-phase materials, weak grain boundaries or residual

Commentary: Toughen up

BMJ, 2009
Most readers of the BMJ will, I’m sure, be stunned by the revelations in Karl Sabbagh’s article (doi:10.1136/bmj.a2066). A deluge of nearly 1000 hostile emails will strike most as the stuff of nightmares. The language of some of those missives—abusive and bigoted—will have seemed truly shocking.

Toughening by Pores

1998
Sintered powder materials being made without hot isostatic pressing are porous. Porosity is an undesirable structural parameter that significantly deteriorates the mechanical properties of the material.
