    摘要： A prepreg is a blend of a fiber reinforcement, a matrix resin and a filler. Based on 100 parts by mass of the prepreg, the fiber reinforcement is 20-60 parts by mass, the matrix resin is 20-65 parts by mass, and the filler is 10-40 parts by mass. The filler is a flame-retardant organic microsphere or a blend of the flame-retardant organic microsphere and an inorganic filler, and the particle size of the filler is preferably 0.1 microns to 15 microns. A copper-clad laminate and a printed circuit board are also disclosed. In various embodiments, the stability of material properties of the prepreg can be improved, the prepreg manufacturing process is simplified, the prepreg production efficiency is improved. Due to the high production efficiency of the prepreg, the manufacturing cost of the prepreg, the copper-clad laminate and the printed circuit board can be reduced.

    摘要： A multilayer radar-absorbing laminate includes three juxtaposed blocks.
    A first electrically conductive block is arranged toward the inside of the aircraft in use.
    A second electromagnetic intermediate absorber block has a layer of electrically non-conductive fiber sheets is permeated by graphene-based nanoplatelets to achieve a periodic and electromagnetically subresonant layer, the conductive layers containing graphene nanoplatelets alternating with non-conductive layers.
    A third block of electrically non-conductive material is arranged towards the outside and forms part of the outer surface of the aircraft. The second block is produced by depositing on the fiber sheets a suspension of graphene nanoplatelets in a polymeric mixture, with controlled penetration of the graphene nanoplatelets into the fiber sheets. A plurality of dry fiber sheets sprayed with the suspension of graphene nanoplatelets is superimposed. An unpolymerized thermosetting synthetic resin is infused into a lay-up made of the first, second and third blocks. Afterwards, the thermosetting resin is polymerized.

    摘要： A remote frequency communication device and method of embedding the device into a physical product build from carbon fiber materials whereby the communication device can interact with an interrogation device such as a mobile phone or tablet. The method provides steps to layer the communication device in a way that prevents the conductive carbon fiber material from short-circuiting the electro-magnetic field of the interrogating device by integrating insulating and protective layers around the communication device.

    摘要： A composite structure having a number of thermoset resin containing elements and a number of thermoplastic elements and at least one interface between the thermoset resin containing elements and the thermoplastic elements is provided. The thermoset resin containing elements and the thermoplastic elements have functional groups at the interface which bond to each other when the composite structure is cured and the functional groups are independently selected from amines, carboxylic acids, acid anhydrides, oxiranes, and derivatives thereof in their non-bonded condition. Additionally, a blade having such a composite structure is provided.
