Tempering of composites

Composite materials need to be heat treated to achieve best results. Both their final strength and heat-resistance increase. The reason is that epoxy resins do not polymerize completely at room temperature. Though a higher final strength is without question relevant, heat resitance is from a practical point of view much more important. Who wants to have a nicely shaped airplane deform in a hot summer day? Not me! Continue reading “Tempering of composites”
