This paper describes the development of the SWEAT (Salt-Water Energy Accumulation and Transformation) system is directed to cooling applications (5-15°C) in industry and in commercial buildings using waste heat or heat from co-generation at about 80°C. The main focus is on solving the corrosion problem. Therefore a number of polymer...
Wood composite turbine blades have been developed over the last 20 years into a reliable technology suitable for modern advanced wind turbines. This technology is now the only realistic competitor to the more commonly used glass polyester construction but has a number of issues that an alternative or improved manufacturing...
Surgical gowns must have a barrier effect between the sources of infection and the user (i.e. a healthy person), as well as good wearing comfort. They are often made of woven polyester fabrics. Different fabric constructions are available for this purpose; these are evaluated with reference to their barrier properties....
The absorption of water in a single-fiber reinforced epoxy-matrix composite system has been modelled successfully using the Finite Element method. The modelling was achieved by considering an analogy between mass diffusion and heat-flow. The model also assumed that polymer swelling due to water absorption was linear and analogous to thermal...
The discovery of a material fatigue problem on a 90° tee connection on a 24-inch recirculation cooling water line in the Romanian Cernavoda Nuclear Power Plant CNPP, identified following a comprehensive inspection, caused major concern - the plant produces 11% of the power for Romania, and shutdown would have had...
The purpose of this paper is to present fatigue and strength experimental qualifications performed for an all-composite bridge deck. The materials used for the fabrication of this 9.14 m (30 ft) long by 2.74 m (9 ft) wide deck were 76 mm (3 in) pultruded square hollow glass and carbon...
Honeycomb sandwich panels are used extensively for flooring in both military and commercial aircraft. Typically, commercial aircraft flooring is about 1cm thick and is made of glass or carbon fiber reinforced epoxy skins with a Nomex honeycomb core. Commercial aircraft floors are designed to withstand high compression loads, particularly those...
An environmental aging test protocol for evaluation of environmental durability of concrete wrapped with fiber-reinforced polymer FRP composites is proposed. The wrap material was made of E-glass and aramid woven fabric impregnated in an epoxy resin matrix. The effect of temperature, moisture, pH level, and freezing and- thawing cycles on...
This paper presents the stress intensity factors for internal and edge cracks in multi-layer glass/epoxy plain weave fabric laminates subjected to uniaxial tension load at cryogenic temperatures. Cracks are considered to have occurred in the transverse fiber bundles. Finite element analysis of the limiting case when the cracks extend to...
The M & A Researcher submits: The European Commission has conditionally approved the Huntsman Corporation HUN - Hexion Specialty Chemicals transaction. Excerpts from the official EC press release included the following: To remove the Commission's concerns, Hexion offered to divest all facilities belonging to its...
Todd Sullivan submits: Here is the big one. The point that cannot be stressed here is the $10 per share earnings estimate in 2010 assumes below average growth and does NOT TAKE INTO ACCOUNT USES OF THE KUWAIT SALE PROCEEDS... Todd: Recently you said that...
