Abstract: The present invention provides an improvement relating to a method for producing a fiber-reinforced resin article at least partially having a structure comprising a bent or curved wall surface, such as a hollow structure part or a U-shaped cross-sectional structure part. A method for manufacturing a fiber-reinforced resin article according to the present invention has a molding step of heating, in a press metal mold, a prepreg preform together with a core comprising a wax material to obtain a cured product and a core removal step of removing the core from the cured product, where the core has an expansion part comprising a first wax material and a stamper part comprising a second wax material that is incompatible with the first wax material, the stamper part is disposed on a surface of the core, and a portion mirroring a shape of a surface of the stamper part is formed on a surface of the cured product.

Abstract: A liquid resin composition comprising: a first proportion of acryloyl morpholine monomers; a second proportion of a photoinitiator exhibiting photodissociation into reactive subspecies responsive to selective exposure to radiation within a spectrum, the reactive subspecies polymerizing the first proportion of acryloyl morpholine; a third proportion of a radiation blocker absorbing radiation within the spectrum to limit penetration depth of incident radiation within the spectrum in the liquid resin; a fourth proportion of a polymerization inhibitor limiting an average chain length of acryloyl morpholine polymer polymerized from the first proportion of acryloyl morpholine monomers; and a fifth proportion of a temperature-stabilizer increasing the heat-deflection temperature of acryloyl morpholine polymer polymerized from the first proportion of acryloyl morpholine monomers.

Abstract: A method of making a multi-section tank with composite material includes pre-tensioning the composite material, wrapping a soluble tool in the composite material, and curing the composite material around the soluble tool. The composite material is pre-tensioned with force to align fibers in the composite material.

Abstract: A process for molding a hollow structure comprising the steps of: a. Forming a mandrel in a shape of a proposed cavity from a water-soluble substance capable of withstanding temperatures and pressures from a predetermined compression molding process; b. Positioning the mandrel in a suitable mold for forming an article which includes the mandrel within the article; and, c. Removing the mandrel by loosening and dissolving the mandrel with a water solution, thereby creating a cavity in the article.

Abstract: A method for producing wound hollow profiles having variable curvatures and cross-sections. In this case, a core having at least one curvature or cross-sectional change is moved in a translatory manner relative to a system having at least a first and a second fibre feed which cause the formation of an axial fibre reinforcement and at least one first wound layer.
