This book is the first to deal with the important topic of the fire behaviour of fibre reinforced polymer composite materials. The book covers all of the key issues on the behaviour of composites in a fire. Also covered are fire protection materials for composites, fire properties of nanocomposites, fire safety regulations and standards, fire test methods, and health hazards from burning composites.

High performance polymeric composites were investigated for their utilization in more hostile conditions in terms of temperature, humidity, and cycling. A number of commercially available composite systems and model systems developed in the Polymeric Composites Laboratory were selected in this study. The addition of rubber to the cyanate ester matrices was found to reduce the rate of matrix deterioration but caused a substantial increase in water uptake. The addition of a thermoplastic modifier to the cyanate ester matrices increased the thermal stability of the matrices more than the elastomer modifier, however, it did not affect the degradation of the material since degradation was mainly governed by the cyanate ester network. Fiber reinforcement and solvent content of an epoxy matrix composite changed the water absorption rate and mechanical properties of the composite. The changes observed in the hygrothermal cycling studies were examined with the transient simulated laminate methodology using unsymmetric laminates. Finally, a model using equivalent cycle time combined with time-temperature superposition theory was proposed to study long-term properties of composites.

From the late-1960’s, perfluorosulfonic acid (PFSAs) ionomers have dominated the PEM fuel cell industry as the membrane material of choice. The “gold standard’ amongst the many variations that exist today has been, and to a great extent still is, DuPont’s Nafion® family of materials. However, there is significant concern in the industry that these materials will not meet the cost, performance, and durability requirementsnecessary to drive commercialization in key market segments – es- cially automotive. Indeed, Honda has already put fuel cell vehicles in the hands of real end users that have home-grown fuel cell stack technology incorporating hydrocarbon-based ionomers. “Polymer Membranes in Fuel Cells” takes an in-depth look at the new chem- tries and membrane technologies that have been developed over the years to address the concerns associated with the materials currently in use. Unlike the PFSAs, which were originally developed for the chlor-alkali industry, the more recent hydrocarbon and composite materials have been developed to meet the specific requirements of PEM Fuel Cells. Having said this, most of the work has been based on derivatives of known polymers, such as poly(ether-ether ketones), to ensure that the critical requirement of low cost is met. More aggressive operational requi- ments have also spurred the development on new materials; for example, the need for operation at higher temperature under low relative humidity has spawned the creation of a plethora of new polymers with potential application in PEM Fuel Cells.
