Tribology of Plastic Materials

Tribology of dental materials: a review

The application of tribology in dentistry is a growing and rapidly expanding field. Intensive research has been conducted to develop an understanding of dental tribology for successful design and selection of artificial dental materials. In this paper, the anatomy and function of human teeth is presented in brief, three types of current artificial dental materials are summarized, and their adva...

Fiber reinforced plastic composites using recycled materials

This work investigates the feasibility of using recycled high density polyethylene (rHDPE), recycled polypropylene (rPP) and old newsprint fiber (ONP) to manufacture fiber reinforced composites. The boards were made through air-forming and hot press. The effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...

Scaling Effects on Materials Tribology: From Macro to Micro Scale

The tribological study of materials inherently involves the interaction of surface asperities at the micro to nanoscopic length scales. This is the case for large scale engineering applications with sliding contacts, where the real area of contact is made up of small contacting asperities that make up only a fraction of the apparent area of contact. This is why researchers have sought to create...

Prediction of Diffusion Coefficients in Plastic Materials

Plastics properties can be tailored through control of their syntheses and processing to fit every desired application, packaging beeing a major one. Measurable residual amounts or conversion products from the many different raw materials and processing aids used in the various plastic synthesis processes can remain in the finished material along with many chemically different additives which a...
