The principal effects of mass degradation on polymer matrix composites (PMCs) are the decay of mechanical properties such as strength, elongation, and resilience. This degradation is a common problem of the PMCs under thermal cycling conditions. In this article, composite degradation was investigated by measurement of total mass loss (TML) using the Taguchi approach. Thermal cycling tests were ...

Background Increasing urban bicycling has established net benefits for human and environmental health. Questions remain about which policies are needed and in what order, to achieve an increase in cycling while avoiding negative consequences. Novel ways of considering cycling policy are needed, bringing together expertise across policy, community and research to develop a shared understanding o...

BACKGROUND Cycling is important for health, transport, environmental and economic reasons. Newspaper reporting of cycling reflects and can influence public and policy maker attitudes towards resource allocation for cycling and cycling infrastructure, yet such coverage has not been systematically examined. METHODS The Factiva electronic news archive was searched for articles referring to cycli...

The degradation process and the electrochemical behavior of two anti-corrosion anti-fouling coating systems (FW-1 FW-2) in a simulated diurnal cycling immersion environment (3.5% NaCl, 35 °C 12 h + 25 h) were investigated by impedance spectroscopy (EIS) technology. Combined with gloss, color difference, adhesion strength scanning electron microscopy (SEM) tests, micro morphologies variations pe...
