Self-sealing of thermal fatigue and mechanical damage in fiber-reinforced composite materials
… across the tank walls. In this dissertation, self-healing functionality is imparted to a structural composite to effectively seal microcracks induced by both mechanical and thermal loading cycles. Two different microencapsulated healing chemistries are investigated in woven glass fiber/epoxy …

The Manufacturing and Ballistic Testing of Tri-axial Quasi Three Dimensional Woven Composites Layered in Polyurea
… study investigates the ballistic resistance and self-sealing nature of a quasi 3D tri-axial woven composite layered with polyurea against high power rifle bullet impact. This is done by evaluating the effectiveness of quasi-3D tri-axial woven composites in resisting .50 caliber rifle rounds and …

Comparison of methods for determining bulk specific gravity of Hma specimens
… measured by Corelok(TM). This is because the self-sealing parafilm bridges over large surface irregularities in contrast to the Corelok(TM), where the polymer Corelok(TM) bag follows the contours of the surface irregularities.

Impacts of Geological Variability on Carbon Storage Potential
… we locate and quantify marine strata that has "self-sealing" properties, a storage option that we find is plentiful off the coasts of the United States. We conclude that further research into transport optimization that takes into account the true variation in geological media is necessary to …

Hybridisation of dental hard tissues with modified adhesive systems: therapeutic impact of bioactive silicate compounds on bonding to dentine
… bonds through crystal formation and self-sealing, in the presence of phosphate buffered saline or simulated body fluid solutions.<br/>In answering these questions, the objectives were accomplished by employing Bioglass® 45S5 in etch-and-rinse bonding procedures either (i) included …

Coupled Hydro-Mechanical Modelling of Gas Migration in Saturated Bentonite
… as it has several desirable properties for sealing the nuclear wastes, including low permeability, low diffusion coefficient, high adsorption capacity and proper swelling ability. Nevertheless, gas migration in saturated bentonite may undermine the sealing ability of the geomaterial. …
