Abstract

A multilayer heating structure for controlling ice accumulation on a surface of an aircraft includes a carbon nano-tube (CNT) heater. The heater includes: a CNT layer; a first encapsulation layer (304) disposed on a first side of the CNT layer formed of a first encapsulation layer thermoplastic material; and a second encapsulation layer (306) disposed on a second side of the CNT layer formed of a second encapsulation layer thermoplastic material. The structure further includes for and aft composite structures (402, 404). The first and second encapsulation layer thermoplastic materials have higher melting temperatures that one or both the fore composite structure thermoplastic material and the aft composite structure thermoplastic material.
