An often overlooked factor in optimizing the ductility of PC is the rate at which the polymer is cooled in the mold.
In the final part of this five-installment series, we bring DMA to a practical level using the results for glass-filled nylon.
The presentation of DMA data can sometimes frustrate users and discourage its adoption. Those unfamiliar with DMA should insist on receiving data relevant to the manner in which the part they are developing will be used.
DMA provides a rich and detailed picture of polymer performance, and it can be challenging to understand all the things that we can and should know about our materials. But the fact that it may be hard does not mean that it should not be attempted.
Glass and carbon fibers are often used to increase material strength and modulus. To maintain these properties, the aspect ratio of these fibers must be maintained.
