This application provides a coating film having excellent durability and wear resistance that, when applied to a mold surface, has excellent releasability (non-adhesiveness) over a long period of time, and a fluoropolymer coating composition that is able to form such a coating film. The fluoropolymer coating composition contains a fluoropolymer and a fluoro oil, where the decomposition temperature of the fluoro oil is higher than the melting point of the fluoropolymer.

A composite material structure manufacturing jig (10) is used when manufacturing a composite material structure by adhering prepreg to a framework structure including a frame component that includes a channel extending along a longitudinal direction of the frame component. The composite material structure manufacturing jig (10) is inserted in the channel of the frame component and used therein. The jig (10) includes a tubular body (11) formed of an elastic material containing a reinforcement fiber, the body (11) including a trapezoidal transverse section that is a cross section orthogonal to a longitudinal direction of the body (11), the trapezoidal transverse section including an upper base and a lower base longer than the upper base. An inner surface of the body (11) is coated with an inner peripheral film (16) serving as a gas barrier layer.

Provided is a coating film having excellent durability and wear resistance, and utility as mold surface release coating. The coating film has excellent releasability (non-adhesiveness) over a long period of time. Further provided is a coating composition capable of forming such a coating film, the coating composition containing a fluoropolymer and an oil that is a liquid at 25° C., wherein the decomposition temperature of the oil is higher than the melting point of the fluoropolymer.

A method of forming a three-dimensional object is carried out by providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; filling the build region with a polymerizable liquid; irradiating the build region through the optically transparent member to form a solid polymer from the polymerizable liquid and advancing the carrier away from the build surface to form the three-dimensional object from the solid polymer, while also concurrently with the irradiating and/or advancing steps: (i) continuously maintaining a dead zone of polymerizable liquid in contact with the build surface, and (ii) continuously maintaining a gradient of polymerization zone between the dead zone and the solid polymer and in contact with each thereof. The gradient of polymerization zone comprises the polymerizable liquid in partially cured form (e.g., so that the formation of fault or cleavage lines between layers of solid polymer in the three-dimensional object is reduced). Apparatus for carrying out the method is also described.
