The study on the tribological properties of fiber-reinforced PBT composites for various injection molding process parameters

Multi-response optimization in friction properties of PBT composites using Taguchi method and principle component analysis

“…During the process, the main design factors such as filling time, melt temperature, mold temperature, and ram speed can greatly affect the fiber condition and change the mechanical properties. In the previous study [5], the influence of various injection molding process factors on the tribological properties of fiber-reinforced PBT was investigated. The study showed that the friction properties are highly dependent on the solidified-intermediate-core morphology that is defined by fiber orientation and exists from free surface to core.…”

“…Injection molding is a very common manufacturing process for reinforced plastics because it provides products with dimensions steadiness and precision, a low manufacture cycle and low cost. However, the author of this study [5,6] and other researchers [7][8][9] have found that some parameters of injection-molding process greatly affect the quality of products. Selecting the correct injectionmolding conditions is always a major concern to the plastics industry.…”

Non-lubricated friction of polybutylene terephthalate (PBT) sliding against polyoxymethylene (POM)

“…Polyoxymethylene (POM) and polybutylene terephthalate (PBT) are among the most frequently used thermoplastic polymers in engineering applications due to their low coefficients of friction, superior mechanical and self-lubricating properties [3][4][5]. Particularly, these polymers are utilized in medical industry for the manufacturing of drug delivery systems, pen injectors, IV (intravenous) and syringe components, connectors, dental instruments, inhalers and equipment housings [6].…”

Fibre orientation of fibre-reinforced PBT composites in injection moulding

“…The author has been interested in the tribological characteristics of fibre-reinforced PBT composites 27 and observed that the tribological properties depend strongly on the frozen-intermediate-core morphology. Following that work, the present study investigates the fibre orientation and distribution of 15 wt-% short fibre-reinforced PBT using both experimentation and computer-aided analysis.…”
