A technique has been developed for producing Light Fibers with Precision Lighting Elements, which emit side light in carefully controlled patterns for exterior lighting applications. Target specifications can now be satisfied with light delivered from a very small, robust package. Conventional lenses and reflectors are not required. Three exterior applications have been targeted: the Center High Mounted Stop Lamp (CHMSL), a Side Marker, and an Emergency Flasher. An optical model of each application has been built, for which basic input parameters are target distribution, fiber diameter, and fiber length. Fiber cores are manufactured with the desired optical elements; cladding and a reflective coating over the notches complete the Precision Lighting Element. Measured intensity distributions from prototypes meet the modeled performance expectations.

This paper will discuss factors which influence attenuation in light fiber systems. These factors include bulk properties of the core material and the cladding material, as well as the characteristics of the core-cladding interface.

Automotive cabin air filters have become increasingly popular as automotive manufacturers recognize the need to provide vehicle occupants with a more comfortable driving experience. Cabin air filters which reduce particulates (e.g. dust, pollen) have been standard on many European models since the late 1980's and have recently become available on several vehicles produced by Ford Motor Company in North America. Market research (focus panels and customer surveys) has shown that consumers expect cabin air filters to reduce both particulates and odors/gases and as a result, future vehicles will offer systems which address both. Test methods and standardized test codes for evaluating these types of filters are currently being drafted. Current methods for testing such gas/odor filters call for part-per-million challenge levels for reasons of analytical simplicity and test speed.

The process of translating customer needs into successful commercialized products and services has been the subject of many books, articles and papers [1, 2, 3, 4, 5, 6]. This process has many facets and nuances depending on the type of product or service being developed. Factors impacting this translation include the target audience, cost, timing and return on investment. While some of these factors may be more important than others for any given project, there are six core elements that are present in every successful new product commercialization venture: Commercialization Components: Customer Understanding Technology Understanding Customer Feedback Market Awareness People and Process: Skilled Project Management Commercialization Process In this paper we will define and describe these core elements and some of the important building blocks, tools and tactics. We will illustrate with real-world examples how these elements are used and measured.

Abstract Because of the increasing concern with vehicle weight, there is an interest in lightweight materials that can serve several functions at once. Here we consider the vibration damping performance provided by an “acoustical” material (i.e., a fibrous layer that would normally be used for airborne noise control). It has been previously established that the vibration of panel structures creates a non-propagating nearfield in the region close to the panel. In that region, there is an oscillatory, incompressible fluid flow parallel to the panel whose strength decays exponentially with distance from the panel. When a fibrous medium is placed close to the panel in the region where the oscillatory nearfield is significant, energy is dissipated by the viscous interaction of the flow and the fibers, and hence the panel vibration is damped. The degree of panel damping is then proportional to the energy removed from the nearfield by the viscous interaction with the fibrous medium.

To insure adequate adherence of coatings to metal surfaces, the coil coating industry has historically used abrasive brushes to clean and prepare the substrate. The use of 3-dimensional, nonwoven abrasive brushes to generate a surface finish, remove contamination, and increase the bondability of the coating to the strip is highlighted in this report. The role of chemical cleaners, as well as other abrasive type brushes is also discussed. The continued production of Zincrometal and other precoated materials for use in automotive applications attests to the high performance levels that are achieved by the coil coating process.
A retired military officer who was the development manager for the U.S. Department of Defense's $3 trillion, six-year Future Year Defense Plan wants suppliers to know that the military wants innovative product solutions.
The use of a nickel, manganese, and cobalt (NMC) cathode materials for use in lithium-ion batteries is expected to increase under a licensing agreement that allows Umicore to make and sell the materials developed by 3M.
Working with supplier 3M, General Motors engineers have developed what they claim is an industry-first LED taillight technology that delivers a soft, uniform red glow in a complex and unique shape. It is being deployed first on the MY2013 Buick Enclave, then will be cascaded to other Buick models, the company says.
Operating helicopters in very difficult climatic conditions in Iraq and Afghanistan can result in the need to replace rotor blades after only 400 flying hours’ time because sand, grit, and gravel have such a severe abrasive effect. To improve the operating life span of the BERP III blades fitted to AgustaWestland Lynx helicopters, the type operated in both countries by British Forces, 3M has developed a protective polyurethane coating.
Weight reduction is already a significant consideration in companies’ product development efforts, and the emphasis is only going to increase in the years ahead, according to SAE-member survey respondents.
3M and Chesapeake Energy Corp. are collaborating to design, manufacture, and market a portfolio of compressed natural gas (CNG) tanks for use in various transportation sectors in the U.S. The companies note that currently the fuel tank on a CNG vehicle is its most expensive single component but claim that the new CNG tanks stemming from their partnership will reduce costs and increase performance.
Lightweight vehicles of the future will require strong carbon-fiber composite structures, but low-cost fibers are needed for market viability. Overcoming the challenges to cheaper carbon fiber is exactly what a research team at Oak Ridge National Laboratory is aiming to do at its new Carbon Fiber Technology Facility in Tennessee.

3M worked closely with automakers on some recent hybrid programs, including Toyota’s Prius and Auris and Honda's CR-Z, to apply its specially developed versions of Thinsulate material, which is also finding application in off-highway, commercial vehicle, and aerospace sectors.
Current products from 3M can be used to repair aluminum- and carbon fiber-intensive vehicles, but the company is working with OEMs such as General Motors to develop optimized solutions for multi-material structural applications.
Recognizing the criticality of cultivating American expertise in the development and production of lithium-ion batteries for automobiles, the U.S. Department of Energy is supporting a new government-industry alliance to do just that.
Advanced insulation packages, solar reflective film, and other thermal-management technologies enable heavy vehicles to reduce idle climate control loads, as demonstrated by NREL's CoolCab project in collaboration with industry OEMs and suppliers.
Meeting safety requirements in all aspects of aerospace production and engineering demands high levels of expertise. Now, specialist technology company 3M has developed what it believes to be the world’s first two-part structural epoxy adhesive to meet aerospace fire, smoke, and toxicity (FST) standards (when tested stand-alone) without the need for additional treatments or surface coatings.
Automotive window tinting can be a relatively high-cost item, but taping is a potentially financially effective alternative. One example: the use of 3M’s adhesive transfer tape has helped OE Sunshades, a manufacturer of automotive privacy shades, to accelerate lead times and switch production from the Far East.
