Biofuels: Illusion or Reality?

2008-09-01
Environmental issues, rising prices and security of supply are putting energy at the center of all attention. Policymakers pushed by various stakeholders are struggling to find more sustainable solutions to the world’s legitimate demand for energy. The transport sector is especially under pressure as it relies up to 98% on oil. Despite vast research and development investments, no short-term solutions appeared to be reliable. Thanks to lawmakers’ support to biofuels, these substitutes for oil are now seen as the potential solution for a sustainable future in less polluting transportation alternatives. This book analyses the real possibility of biofuels in Europe. Does the region have enough land to produce the needed feedstock? What are the real gains in terms of greenhouse gases emissions and energy efficiency? Are biofuels really a sustainable solution? Will this policy succeed? Are the targets reachable?

The Modeling of Mold Filling in Structural Reaction Injection Molding

1996-04-01
91A118
The main use of FRC in automobiles, with the exception of a few specialized low volume vehicles, has been until now in semistructural parts. One of the most promising process in development today, that may play major role in future structural composite fabrication, is based on SRIM technology. The rapid and extensive introduction of this process goes also through the development of deeper theoretical knowledge of the process and the development of computer simulation to aid mold design and choice of proper processing parameters. To contribute SRIM advancement, a preliminary model has been developed for viscosity changes, extent of the reaction and temperature rises, associated with the mold filling stage, as well as a simple software to evaluate the pressure drop through different combinations of reinforcements.

Particulate Reinforced Aluminum Matrix Composites Obtained By Indirect Squeeze-Casting

1996-04-01
91A115
Indirect squeeze casting technology is one of the most attractive fabrication techniques of near net shape components constituted by aluminum matrix composite (AMC) materials. AMCs reinforced with both continuous and discontinuous ceramic elements have been mainly produced by infiltration of porous preforms. Nevertheless, a further promising production route offered by this technique is given by the possibility to employ ingots of pre-reinforced aluminum alloys containing ceramic particles (silicon carbide or alumina); ingots are remelted and, under suitable operative conditions, high quality composite castings of simple and complex shape are produced by squeeze casting. The present paper describes the results of an extensive experimental work carried out by Alures-Centro Tecnico Porcessi on a pilot plant scale employing a vertical squeeze casting machine with a clamping force of 315 tons.

Thermomechanical Behavior and Wear Resistance of Whisker Or Particle Reinforced Ceramics

1996-04-01
91A107
Ceramic composite materials have been intensively studied during the last years. Particles and whisker reinforcement have shown the simultaneous advantage to allow the preparation of composite materials by conventional processing and to lead, when under optimum conditions, to dramatic toughening and strengthening. Since wear resistance of brittle material have been shown to be related to both hardness and toughness, composite materials with improved were resistance have been developed for cutting tools or bearing applications. However the mechanism responsible for toughening is of major important for wear resistance effectiveness. We have therefore reviewed the main mechanisms before presenting some examples of composites materials for wear resistance applications.

Antiwear Properties and Applications of Thin Hard Coatings

1996-04-01
91A106
Different techniques, like PVD, CVD, ion implantation, are increasingly used to produce thin film layers of ceramic compounds to modify the surface properties of metals, carbides, ceramics or polymeric components for specialized conditions or in severe conditions of use. Carbides, nitrides, oxides, etc. have been deposited on the most varied supports to solve problems of high temperature, erosion, corrosion, diffusion and conductivity or electrical resistance. The fields of thin hard coating applications are: tools, dies, punches, mechanical components (for antiwear deposits), structures (for anticorrosion), optics (reflecting or absorbing layers) and microelectronics. In this paper we will present the principal characteristics of different thin hard coating layers and processes, and the principal applications in the anti-wear field.

Trends and Forecasts for Turbocharging

1988-03-01
871147
Predictable and unpredictable forces will change the direction of the charge-air systems industry. The driver of diesel engine development will be the stringent emissions regulations of the 1990s. The drivers in the gasoline engine market will be improved fuel economy, performance, durability and emissions. Forces will also influence the charge-air marketplace, including changes in emission standards, national fiscal policies, political issues, fuel prices, alternate fuels and consumer tastes. The world community mandate for engines that are clean, quiet, durable and fuel efficient will be satisfied, increasingly, by first-tier component suppliers developing integrated systems solutions.
