摘要： Provided is an apparatus for producing a joined-resin product in which two or more resin members are joined. The apparatus includes: a surface treatment mechanism comprising an electrode unit generating ionized gas, and a member holding mechanism arranged at a position separated from the electrode unit by a space and holding the resin member, the surface treatment mechanism activating a surface to be joined of the resin member held by the member holding mechanism, by the ionized gas generated by the electrode unit; and a joining mechanism bonding the two or more resin members together where at least one of surfaces to be joined facing each other is activated by the surface treatment mechanism, at the respective surfaces to be joined.

摘要： A preform is obtained by stacking two or more prepreg cut materials, each of which is obtained by cutting a sheet-like prepreg into an outline of a predetermined shape, and the sheet-like prepreg being formed of a matrix resin and reinforcing fibers aligned in one direction. This preform is characterized in that at least one prepreg cut material has first incisions that are regularly distributed throughout the whole in-plane region and a second incision that is longer than the first incision while being provided only in a predetermined specific region.

摘要： The present invention provides a porous carbon fiber which has an excellent permeation amount and excellent pressure resistance, which is prevented from the occurrence of detachment or cracking at an interface, and which can exhibit excellent properties needed for use as a support for a fluid separation membrane. The present invention is a porous carbon fiber having a bicontinuous porous structure, wherein
the average value Rave of the R value of the outer surface and the R value of the inside is 1.0 or more and 1.8 or less,
the absolute value ΔR of the difference between the R value of the outer surface and the R value of the inside is 0.05 or less, and
R value is a carbonization progression degree calculated from a Raman spectrum in accordance with the following formula: R value=(intensity of scattering spectrum at 1360 cm−1)/(intensity of scattering spectrum at 1600 cm−1).-
