...oclave. Subsequently, emission tape (ET) was applied to all laminate surfaces. Thus, a constant emissivity of 0.95 was assumed for all specimens despite possible differences in surface conditions. To ensure that the same convection conditions prevail on both surfaces of a laminate, the specimens were fixed vertically. Afterwards, the specimens were inductively heated (Fig. 3). The maximum temperature on each of the two laminate surfaces was measured by means of two thermal cameras. The used indu...

...re control, extremely precise temperature control is achieved, which contributes to a stable production process. Extreme conditions of over 200 °C and more than 30 bar of system pressure prevail in the pressurized-water temperature control unit during operation. Under these conditions, salty water causes accelerated corrosion. Reactions in the water are accelerated by the high temperature. Chloride in the temperature control medium attacks the passive layer of the metal surface, which in turn le...
