A continuous forming apparatus of a fiber reinforced composite includes a tension detection mechanism, a drive motor, and a drive control device. The drive control device is configured so that a material roll is rotationally driven in a delivery direction of a reinforced fiber base material during a time period from a time point of end of pressurization in a forming process to a time point of end of a pulling-out process, and is also configured to perform tension control on the reinforced fiber base material based on a detected tension value from the tension detection mechanism and a target tension value, during a time period from a time point of start of the pulling-out process to a time point of end of the pressurization in the forming process in a next forming operation.

Continuous forming apparatus of fiber reinforced composite

An object of the present invention is to provide a fiber-reinforced thermoplastic resin sheet which can be manufactured into a molded body exhibiting excellent appearance quality as well as exhibits both high moldability and strength and a manufacturing method of such a fiber-reinforced thermoplastic resin sheet. The present invention relates to a fiber-reinforced thermoplastic resin sheet which is a random laminated body of a tape-shaped unidirectional prepreg and contains spread reinforcement fibers and a polymer (a) and in which the polymer (a) is a polymer of at least a bisphenol A type epoxy compound represented by Formula (1): where n is an integer of 1 to 4and a bisphenol compound selected from the group consisting of bisphenol A, bisphenol F, bisphenol S, bisphenol B, bisphenol E, and bisphenol P.

Fiber-reinforced thermoplastic resin sheet, molded body of fiber-reinforced thermoplastic resin sheet, and manufacturing method of fiber-reinforced thermoplastic resin sheet

A manufacturing method of a tank including a tubular body portion, and dome-shaped side end portions formed on both sides of the body portion, the manufacturing method includes forming a tubular compact serving as at least part of the body portion from one fiber reinforced resin sheet by winding the fiber reinforced resin sheet including reinforced fibers impregnated with thermoplastic resin is wound several times around a peripheral surface of a core from a direction perpendicular to an axial center of the core in a state where the thermoplastic resin is melted.

An object is to provide a method for producing a polysaccharide derivative without using a catalyst, a cocatalyst, or an active compound by esterification, etherification, or the like, from a polysaccharide such as cellulose as a source material, while maintaining a high molecular weight. Another object is to provide a method for producing a cellulose derivative in a separated condition directly from biomass containing lignocellulose. A method for producing a polysaccharide derivative of the present invention is characterized in that a reaction is carried out in a mixture comprising: a source material comprising a polysaccharide; an ionic liquid for which the pKa of a conjugate acid of an anion in DMSO is 12 to 19 and which is capable of producing a carbene; and a chain or cyclic ester compound or an epoxy compound. Preferably as a source material containing a polysaccharide, a biomass source material containing lignocellulose is used.
