Disclosed are: a reinforcing fiber bundle with excellent mechanical property and handling property, which contains a propylene-based resin (A), a propylene-based resin (B) comprising at least a carboxylic acid salt bonded to the polymer chain, and a reinforcing fiber (C) wherein the propylene-based resin (A) comprises more than 70% by mass but not more than 100% by mass of a component (A-1) having a weight average molecular weight of 150,000 or more, the amount of the propylene-based resin (B) is 3 to 50 parts by mass per 100 parts by mass of the propylene-based resin (A), and the total content rate of the propylene-based resin (A) and the propylene-based resin (B) is 0.3 to 5% by mass in the whole reinforcing fiber bundle; and a molding material comprising the reinforcing fiber bundle and a matrix resin.

Provided herein is a molding material that attains little fluctuation in amount of short fibers and powdery resin among individual products and that allows continuous production without damaging a die. In the step of pouring, slurry is poured onto a slurry diffusion member 7 from above the slurry diffusion member 7. The slurry diffusion member 7 extends in an upward direction, and is shaped such that the area of a transverse section taken along a direction orthogonal to the upward direction becomes smaller as the slurry diffusion member 7 extends in the upward direction. In the step of cleaning, a dispersion medium that is the same as the dispersion medium used in the step of pouring or water is poured onto the slurry diffusion member 7 from above the slurry diffusion member 7 to cause the short fibers and the powdery resin adhering to a slurry diffusion portion 71 of the slurry diffusion member 7 to fall down. After that, the dispersion medium is discharged from a cylindrical die 3 to accumulate the short fibers and the powdery resin in the cylindrical die 3 to obtain an aggregate 38 of the short fibers and the powdery resin. Then, the aggregate 38 is compressed.

A molded article of a fiber-reinforced resin contains at least a bundled aggregate [A] of discontinuous reinforcing fibers and a matrix resin [M], wherein the average layer thickness h in the molded article of the fiber-reinforced resin is 100 ?m or less and the CV value of the average layer thickness h is 40% or less; and a compression molding method therefor. It is possible to reliably and greatly reduce the occurrence of stress concentration in the molded article and to thereby achieve higher mechanical properties and further reduce variation in the mechanical properties.

Branched aramid nanofibers (ANFs) can be made by controlled chemical splitting of micro and macroscale aramid fiber by adjusting the reaction media containing aprotic component, protic component and a base. Branched ANFs have uniform size distribution of diameters in the nanoscale regime (below 200 nm) and high yield exceeding 95% of the nanofibers with this diameter. The method affords preparation of branched ANFs with 3-20 branches per one nanofiber and high aspect ratio. Branched ANFs form hydrogel or aerogels with highly porous 3D percolating networks (3DPNs) frameworks that are made into different shapes. Polymers and nanomaterials are impregnated into the 3DPNs through several methods. Gelation of branched ANFs facilitates layer-by-layer deposition in a process described as gelation assisted layer-by-layer deposition (gaLBL). A method of manufacturing battery components including ion conducting membranes, separators, anodes, and cathodes is described. The method of manufacturing of materials with high mechanical performance based on branched ANFs and 3DPNs from them is disclosed.
