Talk: Development Of The First Vehicle In The World Capable Of Carrying Ten Times Its Own WeightThe need for weight reduction has recently motivated the use of better steel, and aluminum to produce lighter chassis in trailers, and the resulting chassis are also inevitably more flexible. On the other hand CSSI has assisted Composittrailer¨ in designing an integrated fiber reinforced chassis and superstructure, which leapfrogs the steel and aluminum trailer technology under development by its competitors.
The combination of the more flexible chassis, and the integrated superstructure has made the chassis-superstructure ensemble design more complex than it used to be when chassis were extremely rigid, so that there was no major interaction in their structural behavior with the bodies, and beam theory (or at most plate theory) was more than sufficient to design safely. A structural analysis using modern computational tools is needed. Very high global weight reduction has been achieved, with evident advantages for the payload, and at the same time increased safety margins.
Notwithstanding the fact that major advances have been madeÉit will be shown that trailer technology has remained essentially unchanged for nearly 6000 years, and that we are still attempting the equivalent of putting a PLC on a steam machine. When properly used however, composites open major new avenues in vehicle technology leading to reduced shipping charges for the customers, increased profit for the fleet operators, and billions in savings for the taxpayers as a result of reduced road damage.

Jim Stemler, currently VP, Sales at Click Bond, graduated from the University of Southern California in 1982. His first Aerospace job was with Cherry Textron (now Textron Aerospace Fasteners). This was a technical support role, with much time devoted to training operators in the field how to properly install blind rivets in aerospace structures.
In 1985 Jim took an outside sales position with Shur-Lok Corporation, which primarily produced potted fasteners for use in cored substrate materials and other composite structure. This provided an introduction to the combination of composite structure, adhesives and mechanical fasteners all in the same application. 1987 was the year Click Bond Inc. was incorporated. Click Bond (Charlie Hutter, Founder) had invented the Òself fixturingÓ adhesive bonded fastener. He invited Jim to Carson City, Nevada (headquarters) and in late 1987, Jim became Click BondÕs first salesman.

Talk: Using Materials to Create Structural Color in Art Red Wolf has created a painting technique utilizing thin film application in the pursuit of creating structural color. In nature structural color is seen in numerous inorganic materials such as opal and even in biological structures such as hummingbird feathers.
This phenomena of structural color and the play of light and interference effects has fascinated humans for thousands of years. Studies using the electron microscope have begin to unravel the mechanism of this phenomena. Creating structural color has become one of the most sought after developments in the pigment industry and it continues to prove difficult and expensive to create commercially. Red Wolf's artwork represents a unique exploration into this development of control and creation of color through the manipulation of light.
In addition to describing his experiences in creating his artwork, Red Wolf will describe some of the materials issues that have arisen has he applies some of these advanced materials in his artwork. These include: the stability of outdoor coatings, crazing of vinyl coatings, bubbles formed during cure of his epoxy coatings, use of vacuum bagging/pressure to control bubbles during cure, embedding of diffraction grating materials, use of honeycomb aluminum panels to back his art, etc.

Red Wolf, Artist www.RedWolfFineArt.comRed Wolf is an artist who uses technological materials to create color through the interaction of layered materials and light at a microscopic scale. Red Wolf's work began as a modern adaptation of the glazing techniques of the Old Flemish Masters. In addition to the full artist's materials palate, he utilizes modern industrial materials: plastics, polymers, sealers, and various optical enhancers. He is developing ways to manipulate the refractivity of light entering and exciting his paintings. Having the ability to manipulate the refractivity of the painting matrix, the bending and control of light becomes equally important to the manipulation of pigments in constructing the fine art image. |

Talk: Composite Surface Design The ability to use a material depends to a large degree on the ability to sculpt the material into a usable part and to subsequently connect that part to others. Composite are well known to add value to the process by allowing a user to convert a raw material in one state (fiber & liquid resin) into a sculpted finished part in another state. Unlike metallics, this process can also be utilized to generate the desired surface finish in one easy step. However, the ease by which a bad surface can be generated is equally easy. This talk will focus on how to go about designing the desired surface, how to go about fabricating it, and some of the pitfalls along the way. Specific discussion points will include the best surfaces for bonding operations, and Òhow toÓ studies into carbamate formations.

Dr. Tracy Colwell, Materials and Processes, Lockheed Martin Space Systems Co.
Tracy came originally from Menlo Park before heading off to UC Davis for a BS in Aeronautical & Mechanical Engineering. Realizing that CFD was not desireable for the next 30 years, he moved on to higher education at Stanford in Aeronautics & Astronautics in the Structures and Composites Lab. Obtaining his Ph.D. in '96 was a mixed blessing since it required a transition into the real world to earn a living. Lockheed Martin assumed the roll of family sponsor. Despite hating composite design at UCD, and taking few materials specific classes, Lockheed decided to place him in the roll of senior Materials & Processes engineer based sole on the strength of his hands-on composites experience at Stanford. Little did they know that the typical technician at Lockheed had more experience. Despite that, Tracy has since published ~30 in-house papers with various members of the LM staff, most dealing with the test, evaluation, design, and failure investigation of composite materials.
