Other preferred matrices are structural thermoplastics such as polyether ether ketone (PEEK), polyether ketone ketone (PEKK), polyphenylene sulfide (PPS) or polyetherimide.
     The polymer matrix of the at least two outer (2) and (2 ’) sheets of the composite material of the present invention further comprises reinforcing fibers. The term "reinforcing fiber" should be understood as a fiber of an organic or inorganic material capable of conferring an improvement in the mechanical properties of the polymer matrix.
     Non-limiting examples of reinforcing fibers suitable for the composite material of the present invention include carbon fibers, glass fibers, aramid fibers, polymeric fibers (such as, for example, phenylene benzobisoxazole, polyethylene or polypropylene) fibers, textile fibers ( such as natural fibers of cotton or wool) and ceramic fibers.
     In a particular embodiment, the reinforcing fibers are carbon fibers.
    In a preferred embodiment, each of the at least two outer (2) and (2 ′) sheets of the composite material of the present invention has a thickness of between 1 and 100 mm, more preferably between 5 and 30 mm.
    The composite material of the present invention further comprises, such and as has been
     mentioned above, at least two inner sheets (3) and (3 ’), where each one comprises carbon nanotube fibers.
    In the context of the present invention, the term "carbon nanotube" refers to a structure considered as coming from a sheet of graphite wound on itself. Depending on the degree of winding, and how the original  sheet is formed, the result can have ananotubes of different diameter and internal geometry. The carbon nanotubes formed as if the ends of a sheet were joined by their ends forming the aforementioned tube, are called "monolayer nanotubes" or "single wall." Carbon nanotubes whose structure resembles a series of concentric tubes, included within each other,
     Matrioskas dolls, logically, of increasing diameters from the center to the periphery are called “multilayer nanotubes”.

    In a preferred embodiment, the salt is an ionic liquid.
     The term “ionic liquid” refers to liquid asales at room temperature, which are constituted by an organic or inorganic cation and an organic or inorganic union. Non-limiting examples of ionic liquids suitable for the polymer electrolyte of the composite material of the present invention include bulky and asymmetric organic cations such as 1-alkyl-3-methylimidazolium, 1

    The PYR14TFSI ionic liquid has a wide window of electrochemical stability and high ionic conductivity. On the other hand, the PVDF-co-HFP copolymer has high
     mechanical properties and semicrystalline character as polymer matrix.
    In a preferred embodiment, the polymer electrolyte has a thickness between 1 and 100 µm, more preferably between 1 and 50 µm, even more preferably between 1 and 20 µm, even more preferably around 10 µm.

    Magnetic and ultrasonic. The solution with these three components is injected even pre-evaporator (pre-heater) where the mixture is evaporated to then continue to a reactor that operates at a temperature between 1000 and 1400 ° C. In addition to the mixture, a stream of hydrogen is injected into the reactor. Inside the reactor, the reaction of the components of the initial mixture occurs, so that a carbon nanotube airgel is generated. From the bottom of the reactor, a rod is introduced that causes the agglomeration of said carbon nanotube airgel at the same time as said agglomerate adheres to the iron and is extracted from the reactor in the form of fiber. As the fiber formed is extracted, it is wound with
     help of rotating rollers, thus forming a condensed fiber. The procedure allows to obtain a fiber with a long length in a short period of time (see Figure 2a).
    The resulting carbon nanotube fibers can be deposited in-situ on a laminar support, such as a sheet of macroscopic fiber fabric
     such as Kevlar fibers, carbon fiber glass fibers.
    Once the sheets with the carbon nanotube fibers are obtained, the polymer electrolyte is assembled between at least two of them. Assembly takes place by impregnation methods in oenseco solution. In this way, the impregnation of the polymer electrolyte takes place in the pores of the sheets that
     comprise carbon nanotube fibers.
    Non-limiting examples of solution impregnation methods suitable for the preparation method of the present invention are immersion coating, spin coating, casting, spray coating, brushing and infusion, which are more preferably followed by a drying step.

    The method of the present invention further comprises a step b) of interleaving the
     structure resulting from step a) between the at least two (2) and (2 ’) outer sheets comprising a polymer matrix and reinforcing fibers to give rise to a sandwich structure.
    The outer sheets (2) and (2 ’) comprising a polymer matrix and reinforcing fibers can be previously prepared following methods known in the state

    The resulting structure of Example 1 was sandwiched between two sheets of resin
     epoxy containing embedded carbon fibers. This procedure was carried out by applying pressure on the combination obtained. A pressure of about 4MPa normal was applied to the plane of the laminar structure, using a pneumatic laboratory press of the CARVER brand model 3853. Subsequently, the resulting structure was cured in an oven at 60 ° C for two hours.
     Figure 4 (a) shows a structural supercapacitor comprising the resulting sheet composite material and Figure 4 (b) shows the resultant sheet material power and energy density during the different stages of the manufacturing process.
