    摘要: The invention refers to a panel structure (1) for an aircraft comprising at least one composite layer (3, 4) and at least one carbon nanotube (CNT) paper (2) laid over the at least one composite layer (3, 4), wherein the CNT paper (2) comprises an aggregation of carbon nanotubes suitable to be heated up to the curing temperature of the panel structure (1). The CNT paper (2) can be attached between two composite layers (3, 4). Alternatively, the CNT paper (2) can be attached to a surface of one composite layer (3, 4) to form the outermost layer of the structure (1) to cure the composite layers (3,4). In this last case, the CNT paper (2) may be covered by an Alkaline Earth Silicate layer (5). The invention provides a heatable panel structure (1). In addition, the panel structure (1) configuration allows the inspection of effects of accidental damages.

    摘要: The invention relates to a structure of composite material (1), comprising a continuous first layer (10) of composite material (1), a second layer (20) of viscoelastic material, and a continuous impact-protection third layer (30). The first layer (10) is formed by structural components in the form of a matrix (11) and fibers (12). The second layer (20) of viscoelastic material is added on top of the first layer (10) and said second layer (20) can be continuous or non-continuous. If a non-continuous second layer is used, elongate, circular or square cavities (25) are arranged inside said layer (20). Optionally, reinforcements (13) comprising carbon nanofibers or nanotubes are provided in either of the first and second layers (10, 20). The third layer (30) of impact-protection material is added in a continuous manner on top of the second layer (20), said third layer (30) forming the outermost layer of the composite material (1). In addition, this third layer (30) is electrically conductive. The composite material (1) has noise attenuation, impact resistance and electric conductivity properties.
