Characterisation of the Moisture Absorption and Thermal Ageing Behaviour of Polymeric Composite Systd application in the manufacture of e.g. boat hulls, high performance motor vehicles, aircraft components and sports goods. Their high specific strength and specific stiffness give them the edge in applications where weight savings are critical, but their long-term durability is often questioned. Th

Ageing Processes of Nitrocellulose in Plastic Bonded Explosivesexplosives industry. The decomposition kinetics of NC have been investigated by ageing nitrocellulose-containing PBXs at elevated temperatures and monitoring the reduction in NC molecular weight using gel-permeation chromatography (GPC). The kinetics can be described by a first order, random chain s

Ageing Study of Polyetheretherketone Exposed to Water and Brine by Thermal Analysis and Dielectric Smeasurement, dynamic mechanical thermal analysis (DMTA), differential scanning calorimetry (DSC) and dielectric spectroscopy. It is observed that plasticisation of a crystallite distribution generated in the formation of the sample occurred during the water uptake process. The water and brine sorpti

The Effects of Gamma Radiation Sterilisation on Ultra High Molecular Weight Polyethylenet it is chemically identical to HDPE, the large chain length of UHMWPE confers on it the greatest abrasion resistance of any similar thermoplastic, with other favourable properties such as low coefficient of friction and high impact resistance. As UHMWPE also has good biocompatibility, it is commonl

Ageing Characteristics of Gamma Irradiated Ultra High Molecular Weight Polyethyleneuses both immediate and time dependent chain scission processes to occur, releasing material for further crystal growth, leading to an increase in stiffness and predisposing the surface to wear..C NMR was used to characterise the aliphatic region of UHMWPE on the basis of differences in chemical shi
