Advanced Composite Materials for Automotive Applications: by Ahmed Elmarakbi

By Ahmed Elmarakbi

The car faces many demanding situations, together with elevated international pageant, the necessity for higher-performance cars, a discount in expenses and tighter environmental and defense standards. The fabrics utilized in automobile engineering play key roles in overcoming those concerns: finally lighter fabrics suggest lighter cars and decrease emissions. Composites are getting used more and more within the car because of their power, caliber and lightweight weight.

Advanced Composite fabrics for automobile purposes: Structural Integrity and Crashworthiness offers a complete rationalization of the way complex composite fabrics, together with FRPs, strengthened thermoplastics, carbon-based composites and so forth, are designed, processed and used in cars. It comprises technical motives of composite fabrics in motor vehicle layout and research and covers all levels of composite layout, modelling, trying out and failure research. It additionally sheds mild at the functionality of present fabrics together with carbon composites and destiny advancements in automobile fabric know-how which paintings in the direction of lowering the load of the motor vehicle structure.

Key features:

  • Chapters written through world-renowned authors and specialists of their personal fields
  • Includes exact case reviews and examples overlaying all points of composite fabrics and their software within the car industries
  • Unique subject integration among the impression, crash, failure, harm, research and modelling of composites
  • Presents the cutting-edge in composite fabrics and their program within the automobile industry
  • Integrates concept and perform within the fields of composite fabrics and car engineering
  • Considers power potency and environmental implications

Advanced Composite fabrics for car purposes: Structural Integrity and Crashworthiness is a complete reference for these operating with composite fabrics in either academia and undefined, and can also be an invaluable resource of knowledge for these contemplating utilizing composites in automobile functions within the future.

The Corvette in the Barn

It's each car-guy's fantasy—to casually peer right into a long-forgotten storage or barn or warehouse and locate the auto he has hunted for his entire lifestyles. Corvette within the Barn is a set of real, frequently remarkable, tales and essays approximately motor vehicle creditors and lovers who've chanced on strange and fascinating autos, forgotten in all demeanour of destinations from barns, to old-school junkyards, to farmer's fields.

Sustainable Automotive Technologies 2013: Proceedings of the 5th International Conference ICSAT 2013

This publication captures chosen peer reviewed papers awarded on the fifth foreign convention on Sustainable automobile applied sciences, ICSAT 2013, held in Ingolstadt, Germany. ICSAT is the cutting-edge convention within the box of latest applied sciences for transportation. The publication brings jointly the paintings of overseas researchers and practitioners below the subsequent interrelated headings: gas transportation and garage, fabric recycling, production and administration bills, engines and emission relief.

Simulation of the Noise Transmission through Automotive Door Seals

Andreas Hazir is investigating the door seal contribution to the internal noise point of creation autos. those investigations comprise experimental contribution analyses of genuine construction cars and of educational try out situations in addition to the improvement of a simulation method for noise transmission via sealing platforms and aspect home windows.

Example text

There are two classification systems of composite materials. One is based on the matrix material (metal matrix composites, MMC; ceramic matrix composites, CMC; polymer matrix composites, PMC) and the second is based on the material structure: particulate (random orientation of particles; preferred orientation of particles), fibrous (short-fibre reinforced composites; long-fibre reinforced composites) and laminate composites. The various PMC are classified as thermoplastic and thermosets and can be reinforced with various types of fibres depending upon the applications.

From a historical point of view, it should be noticed that the first car body made from (glass fibre reinforced polymer, GFRP) composites was for the Chevrolet Corvette, which was introduced to the public at Motorama show at New York in 1953 [3]. For these days, the Corvette series still use composite materials in its design. In motor sports, the use of carbon fibre reinforced polymers has been shown in Formula 1, with the McLaren MP4 in 1981. The open wheel car benefits from lighter body, which leads to a well distributed weight in order to achieve more mechanical grip on the track which significantly increases the overall performance of the car.

Woven composites represent the biggest category of textiles. Concerning the 2D woven fabrics, the composite is made of two sets of yarns: the warp and weft yarns. They are interlaced in a 90◦ “in-plane”. In this kind of woven fabrics, one type of yarn (warp or weft) goes beneath only one set of the other type of yarn and they have a sinusoidal longitudinal profile. 2). The 3D woven composites introduce a yarn in the through thickness direction. The 3D woven composites are designed in order to reinforce the third direction and to avoid delamination between the layers.
