Composite parts and structures exposed to high temperatures require a resin matrix designed to withstand the heat. Common resins here include polyimides, bezoxazines, bismaleimides and cyanate esters, among others.
As next-generation aerospace programs demand higher service temperatures in structural and hot section components, a variety of polyimides vie for program approval.
Next-generation aerospace programs demand higher temperatures for structural and hot-section components, fostering advances in thermoset resin chemistry.
