Understanding polyester resin processing: the effect of ambient temperature on final part cure
September 29, 2021 @ 9:00 am - 10:00 am PDT
Controlling the curing parameters of resin, often referred to as thermal management, has a significant effect on the outcome of a thermoset polyester resin and therefore the overall performance of a composite part.
Allowing polyester resin to cure under ambient conditions is the most common technique used in industry. One major drawback of this technique, however, is the lack of control over temperature during the process. Often parts are cured in a facility with little temperature control leaving them susceptible to temperature variation throughout the day, week, month, and year. For example, the outcome of a composite part cured at room temperature in the winter may be different from a part cured in the summer.
In this webinar we will show the effect of ambient temperature on the cure of a polyester resin through experiment and simulation, discuss how this can affect the part, and present techniques to control it.
