摘要： A surface modification method for modifying a surface of, in particular, a polymer material having a ketone group, a bonding method, a surface modified material, and a joined product are provided. The surface modification method is for modifying a surface 10a of a polymer material 10 having a ketone group and includes a contact step and a grafting step. At the contact step, an organic compound 12 having an epoxy group and an unsaturated bond-containing group are brought into contact with the polymer material 10. At the grafting step, light energy 16 is applied to the polymer material 10 being in contact with the organic material 12 to radicalize the ketone group in the polymer material 10, and the radicalized ketone group in the polymer material 10 is reacted with the unsaturated bond-containing group in the organic compound 12 to graft an organic compound chain 20c having the epoxy group based on the organic compound 12 onto a position 10b where the ketone group in the polymer material 10 existed.

摘要： Provided are a compression head for reducing the occurrence of temperature unevenness in a composite material during heating, a composite-material molding device, and a composite-material molding method. A compression head 20 is provided on the other side of a pre-reaction composite material 2 from a magnetic field coil 30 provided on one side of the composite material 2, the compression head 20 facing the magnetic field coil 30 via the composite material 2. The compression head 20 has a compression head body 22 and a high-thermal-conductivity-material layer 24. The compression head body 22 is formed from a material that is transparent to a magnetic field 32 applied by the magnetic field coil 30. The high-thermal-conductivity-material layer 24 is formed on the side of the compression head body 22 that faces the composite material 2, and is transparent to the magnetic field 32 applied by the magnetic field coil 30 and is formed from a material having higher thermal conductivity than the composite material 2.
