Viscoelastic Analysis of Rubber

Viscoelastic Analysis of Rubber

Tires are subjected to cyclical high deformations when vehicles are running on the road. When exposed to harsh road conditions, the service lifetime of the tires is jeopardized by many factors, such as the wear of the thread, the heat generated by friction, rubber aging, and others.

As a result, tires usually have composite layer structures made of carbon-filled rubber, nylon cords, and steel wires, etc. In particular, the composition of rubber at different areas of the tire systems is optimized to provide different functional properties, including but not limited to wear resistant thread, cushion rubber layer, and hard rubber base layer.

A reliable and repeatable test of the viscoelastic behavior of rubber is critical in quality control and R&D of new tires, as well as evaluation of the life span of old tires. Dynamic Mechanical Analysis(DMA) during Nanoindentation is a technique of characterizing the viscoelasticity. When controlled oscillatory stress is applied, the resulting strain is measured, allowing users to determine the complex modulus of the tested materials.

Tribology on Piston Operations

Friction loss accounts for approximately 10% of total energy in fuel for a diesel engine [1]. 40-55% of the
friction loss comes from the power cylinder system. The loss of energy from friction can be diminished
with better understanding of the tribological interactions occurring in the power cylinder system.

A significant portion of the friction loss in the power cylinder system stems from the contact between
the piston skirt and the cylinder liner. The interaction between the piston skirt, lubricant, and cylinder
interfaces is quite complex due to the constant changes in force, temperature, and speed in a real life
engine. Optimizing each factor is key to obtaining optimal engine performance. This study will focus on
replicating the mechanisms causing friction forces and wear at the piston skirt-lubricant-cylinder liner
(P-L-C) interfaces.

A Better Look at Paper

Paper has played a large role in information distribution since its invention in the 2nd century [1]. Paper consists of intertwined fibers, typically obtained from trees, that have been dried into thin sheets. As a medium for information storage, paper has allowed the spread of ideas, art, and history over long distances and through passing time.

Today, paper is commonly used for currency, books, toiletries, packaging, and more. Paper is processed in different ways to obtain properties to match their application. For example, the visually appealing, glossy paper from a magazine is different compared to rough, cold-pressed watercolor paper. The method in which paper is produced will affect the surface properties of the paper. This influences how ink (or other medium) will settle onto and appear on the paper. To inspect how different paper processes affect surface properties, Nanovea inspected the roughness and texture of various types of paper by conducting a large area scan with our 3D Non-Contact Profilometer.
