The turn of the evolution in plastics came with the development of fiber reinforcements. With the introduction of reinforcement fibers to a base resin, the mechanical properties are improved drastically, allowing for the product to be implemented in a wide range of applications. These materials were discovered to have half the weight of their metal counterparts and a tensile strength that is more than doubled. Fibers within the system are ...
Thermal conductivity and thermal diffusivity of two poly(methyl methacrylates) were measured using multiple methods; temperature wave analysis, laser flash, transient plane source, transient line-source probe, and heat flux meter. The main reasoning behind this study was to compare results between methods, to ensure repeatability among methods. Good agreement was shown among thermal conductivity and thermal diffusivity results between instruments, however the transient plane source method repeatedly yielded 6% higher results ...
