Abstract:
The aim of this doctorate is to investigate an alternative to petroleum based thermal insulations, by using natural and recycled materials. The methodology used is centered on the use of the basic ingredients of waste animal fats, waste oils and a potash derived lye mixture, combined to create a crude soap. This soap is aerated to produce a lightweight structure that is capable of preventing or reducing heat transfer between areas of differing temperatures. Experimental testing reveals that this non-toxic product can be strengthened, made waterproof, vermin proof and fire retardant, whilst the

Abstract:
We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. However, the building envelope is just one part of the whole building system, and super insulators have one major flaw: they are easily adversely affected by other problems in the built environment.  Vacuum Insulation Panels are one fresh addition to the arsenal of insulation materials availa

Fibre-reinforced polymeric composites for structural applications are required to conform to specific fire performance requirements and to retain their mechanical integrity after exposure to heat/fire. Many polymeric composites will lose their structural integrity when exposed to temperatures close to the glass transition temperature of the resin matrix. The most effective technique of protecting these materials against heat and fire is the use of surface coatings, which can inhibit or reduce the heat transfer from the fire/heat source to the underlying structure.

Buildings consume more than 30 percent of the primary energy worldwide with 65 percent of this attributed to heating ventilation and cooling. To help address this, stratified concrete panels (SCP) have been developed to provide insulation without compromising the thermal mass of concrete.

Vibration causes the heavy aggregates drop to the bottom so that two distinct strata are formed; an internal structural/heavyweight layer providing thermal mass and an external lightweight layer for insulation.

Abstract:
A comparative Life Cycle Assessment (LCA) was performed on two natural fibre thermal insulation products made from hemp and sheep wool and a benchmark mineral wool product. The assessment revealed both advantages and some disadvantages with the natural fibre materials. A major finding was the particularly low or absent impact in terms of global warming potential shown by the natural fibre materials. This was caused by the renewable carbon sequestered in the material withdrawing carbon dioxide from the atmosphere. With regard to the end of the product life, the study showed that only a proporti

Abstract:
Electrical machines in electrified heavy-duty vehicles are subjected to dynamic temperature loadings during normal operation due to the different driving conditions. The Electrical Insulation System (EIS) in a stator winding is aged as an effect of these dynamic thermal loads. The thermal loads are usually high constant temperatures and thermal cycling. The high average constant thermal load is well-known in the electrical machine industry but little is known about the effect of temperature cycling. In this project, the ageing of the EIS in stator windings due to temperature cycling is examine

Abstract:
The increasing quantity of waste represents serious environmental, social and economic problem. Wastes produced from industry and households. A large part of the economy transforms a certain amount of raw materials to waste in their production, because it is currently emphasis is placed on finding sustainable sources of raw materials. One of the suitable secondary raw materials can be discarded textiles or waste from the textile industry. These kinds of textile waste often ends up in landfills or incinerators, so it is from an ecological and environmentally advantageous to their further use. T

Abstract:
Internal insulation in a solid rocket motor is a layer of heat-barrier material placed between the internal surface of the case and the propellant. The primary function of internal insulation is to prevent the rocket motor case from reaching temperatures that may endanger its structural integrity. An extensive experimental and theoretical work in the development and characterization of asbestos-free rubbers for use as rocket motor insulators has been performed. The insulation is based on chopped carbon fiber and/or aramid fiber in the pulp form as fillers for Ethylene Propylene Diene Monomer

Abstract:
The application of insulation material to the surfaces of airways has the potential of reducing the heat load on the ventilation air of deep mi ne s. This study aims at assessing the viability of this technique. Previous investigations on heat transfer from insulated airways are reviewed and are found to be flawed or out of date. A more reliable thermal analysis is presented This shows that reductions in heat load of 50 to 70 percent can be achieved in fully insulated tunnels, 20 to 40 per cent with partial insulation (footwall uninsulated) and less than 20 per cent with the footwall b
