摘要： Provided is a resin composition from which a three-dimensional molding can be produced at an appropriate speed and with high dimensional accuracy, wherein the obtained three-dimensional molding has high strength. This resin composition is used in a method for producing a three-dimensional molding composed of a cured product of a liquid resin composition by selectively irradiating the liquid resin composition with active energy rays. The resin composition includes at least: a first polymerizable compound, in a liquid state at room temperature, having radical polymerizability; a second polymerizable compound, in a liquid state at room temperature, having no radical polymerizability; and a filler, wherein the surface of the filler is covered with the second polymerizable compound.

摘要： A device for fabricating a composite material part by injecting resin into a fiber structure. The device includes: a first die presenting two adjacent support surfaces defining a reentrant angle between them; at least one chock with a wedge-shaped portion configured to press the fiber structure into the angle; and a second die movable relative to the first die, the first and second dies being configured to clamp on the fiber structure and the chock. The chock is connected to the second die by at least one link, the link being hinged relative to the second die and relative to the chock to guide the wedge-shaped portion towards the angle to press the fiber structure into the angle when the second die approaches the first die.
