Evonik Industries (Frankfurt, Germany) has developed a new polyaryl ether amide resin system called CALIDUR, a single-component system suitable for applications in aircraft manufacturing. It features good fiber adhesion that reportedly helps it improve mechanical properties of bonded fiber materials to create components with high compressive strength and high shear strength. It also provides good temperature resistance, low moisture absorption, and good resistance to chemicals, as well as low exotherm and minimal shrinkage during cure. Fabrics treated with CALIDUR also are said to be more flame retardant than those treated with conventional epoxy resin, thus the material is suitable for aircraft interior applications. CALIDUR also features good shelf-life stability at room temperature.
