    • An electrothermal heater mat (3) is provided for an ice protection system for an aircraft (1) or the like. The heater mat (3) is a laminated heater mat and comprises dielectric layers (50-58), a heater element (501) and a temperature sensor (507). Each dielectric layer (50-58) comprises thermoplastic material, and the temperature sensor (507) comprises a sprayed metal track (5010, 5012) deposited on a substrate (50, 5019) comprising thermoplastic material. The substrate may be one of the dielectric layers (50) or a separate carrier (5019) which is smaller than the dielectric layers (50-58). The substrate (50, 5019) is laminated to at least a first one of the dielectric layers (53, 58) and the thermoplastic material of the substrate is (i) the same as the thermoplastic material of the first dielectric layer such that the thermoplastic material of the substrate is dispersed or merged into the thermoplastic material of the first dielectric layer or (ii) compatible with the thermoplastic material of the first dielectric layer such that the thermoplastic material of the substrate is fused to the thermoplastic material of the first dielectric layer. Thus, the formation of an undesirable discontinuity at the interface between the substrate (50, 5019) and the first dielectric layer (53, 58) is substantially prevented or minimised.
    • 为飞机(1)等的防冰系统提供电热加热器垫(3)。 加热垫(3)是叠层加热垫,包括电介质层(50-58),加热元件(501)和温度传感器(507)。 每个电介质层(50-58)包括热塑性材料,并且温度传感器(507)包括沉积在包含热塑性材料的基底(50,5019)上的喷射金属轨道(5010,5012)。 衬底可以是电介质层(50)中的一个或小于电介质层(50-58)的单独的载体(5019)。 衬底(50,5019)被层压到至少第一个电介质层(53,58)中,并且衬底的热塑性材料是(i)与第一介电层的热塑性材料相同,使得热塑性塑料 衬底的材料被分散或合并到第一介电层的热塑性材料中,或(ii)与第一电介质层的热塑性材料相容,使得衬底的热塑性材料熔合到第一介电层的热塑性材料 。 因此,基本上防止或最小化衬底(50,5019)和第一介电层(53,58)之间的界面处的不期望的不连续性的形成。
