Abstract

Between 1999 and 2002, Pacific Gas Transmission Company (PGT) (now TransCanada Pipeline Company) and AVISTA Corporation, together with technical support provided by the Pacific Northwest National Laboratory and the U.S. Department of Energy (DOE) examined the feasibility of developing a subsurface, natural gas-storage facility in deep, underlying Columbia River basalt in south-central Washington state. As part of this project, the 100 Circles #1 well was drilled and characterized in addition to surface studies. This report provides data and interpretations of the geology and hydrology collected specific to the Canoe Ridge site as part of the U.S. DOE funding to the Pacific Northwest National Laboratory in support of this project.

Abstract

One of the main problems of composites is fire resistance properties. New fire-retardant additives are able to modestly improve this problem, although mechanical properties can be depleted.

For this reason, a large variety of phosphorus-based flame retardants have been studied for their flammability and their rheological and mechanical properties [1,2]. However, little research has been done on the mechanical and rheological properties of epoxy resins with non-halogenated flame retardants, and these must be at least mentioned in conjunction with the fire retardant characteristics, in order to acquire a global view of the compound.

In this work, the correlation between the addition of non- halogenated flame retardants and the mechanical properties of composites (tensile properties, interlaminar shear, flexure) and different types of fiber (basalt and glass) has been researched.
