Article having a three-dimensional extent, more preferably having a sheet-like form, more particularly being in the form of a strip or a sheet or a patch comprising: - a first layer L1 comprising a non-random fabric of bundles of carbon fibres; and - a second layer L2 comprising a thermosetting epoxy resin composition comprising: - 10 - 50 weight%, more particularly 20 - 45 weight%, preferably 20 - 35 weight%, most preferably 20 - 30 weight%, of at least one epoxy resin A having on average more than one epoxide group per molecule; - 1 - 6 weight%, more particularly 2 - 5 weight%, of at least one hardener B for epoxy resins which is activated by elevated temperature; - 0 - 3 weight%, more particularly 0.1 - 2.5 weight%, preferably 0.2 - 0.5 weight%, of at least one accelerator C; and - 10 - 50 weight%, more particularly 15 - 45 weight%, preferably 20 - 25 weight%, of at least one impact modifier D; based on the total weight of the epoxy resin composition, and the thermosetting epoxy resin composition is tacky at room temperature, more particularly, after the surface of the thermosetting epoxy resin composition has been pressed with a thumb, exerting a pressure of 5 kg for 1 second, a thermosetting epoxy resin composition having an intrinsic weight of 50 g can be lifted up for at least 5 seconds, and the second layer L2 has a thickness of 0.4 - 2.5 mm, preferably 0.5 - 2.0 mm. - a first layer L1 comprising a non-random fabric of bundles of carbon fibres; and - a second layer L2 comprising a thermosetting epoxy resin composition comprising: - 10 - 50 weight%, more particularly 20 - 45 weight%, preferably 20 - 35 weight%, most preferably 20 - 30 weight%, of at least one epoxy resin A having on average more than one epoxide group per molecule; - 1 - 6 weight%, more particularly 2 - 5 weight%, of at least one hardener B for epoxy resins which is activated by elevated temperature; - 0 - 3 weight%, more particularly 0.1 - 2.5 weight%, preferably 0.2 - 0.5 weight%, of at least one accelerator C; and - 10 - 50 weight%, more particularly 15 - 45 weight%, preferably 20 - 25 weight%, of at least one impact modifier D; based on the total weight of the epoxy resin composition, and the thermosetting epoxy resin composition is tacky at room temperature, more particularly, after the surface of the thermosetting epoxy resin composition has been pressed with a thumb, exerting a pressure of 5 kg for 1 second, a thermosetting epoxy resin composition having an intrinsic weight of 50 g can be lifted up for at least 5 seconds, and the second layer L2 has a thickness of 0.4 - 2.5 mm, preferably 0.5 - 2.0 mm. - 10 - 50 weight%, more particularly 20 - 45 weight%, preferably 20 - 35 weight%, most preferably 20 - 30 weight%, of at least one epoxy resin A having on average more than one epoxide group per molecule; - 1 - 6 weight%, more particularly 2 - 5 weight%, of at least one hardener B for epoxy resins which is activated by elevated temperature; - 0 - 3 weight%, more particularly 0.1 - 2.5 weight%, preferably 0.2 - 0.5 weight%, of at least one accelerator C; and - 10 - 50 weight%, more particularly 15 - 45 weight%, preferably 20 - 25 weight%, of at least one impact modifier D; based on the total weight of the epoxy resin composition, and the thermosetting epoxy resin composition is tacky at room temperature, more particularly, after the surface of the thermosetting epoxy resin composition has been pressed with a thumb, exerting a pressure of 5 kg for 1 second, a thermosetting epoxy resin composition having an intrinsic weight of 50 g can be lifted up for at least 5 seconds, and the second layer L2 has a thickness of 0.4 - 2.5 mm, preferably 0.5 - 2.0 mm. <EOS>
