The present invention relates to a reinforced composite material and a method for its production. The composite material comprises at least one cured resin having a reinforcing material. Preferably the reinforcing material is a plurality of glass fibers which are treated such that the properties of the interphase substantially surrounding each fiber are substantially equivalent to those of the bulk cured resin. The fiber treatment may be selected from the group consisting of a polymeric coating, a hydrophilic surface coating, a surface coating of a free radical inhibitor, or a reduction in the total surface area of the fibers. The reinforced composite material of the invention provides improved long-term mechanical properties compared to traditional glass fiber reinforced materials.

The present invention belongs to the field of functional fibrous materials, and discloses a magnetic fibrous material and a preparation method and application thereof. A polymer and a magnetic load raw material are dissolved in a solvent to obtain a uniform spinning solution; a solute component that reacts with the magnetic load raw material is added into a coagulation bath solvent to obtain a reactive coagulation bath solution; the spinning solution is electrospun, and the produced fiber is collected with the reactive coagulation bath solution, so that the magnetic load raw material in the fiber reacts in situ with the solute in the reactive coagulation bath solution to obtain the magnetic fibrous material.

Disclosed is a flexible composite prepreg material. The prepreg material includes a fiber bundle of fiber tows having a predetermined cross-sectional shape, wherein exterior surface fibers of said fiber bundle have a thin, irregular sheath of matrix resin on and around said exterior surface fibers of said fiber bundle, wherein substantial number interior fibers filaments remain uncoated by the matrix resin, with discreet areas of through the thickness resin bridges made of the matrix resin.

Solutions formed by combining poly((1.fwdarw.3) glucan) with CS.sub.2 in aqueous alkali metal hydroxide solution have been shown to produce the xanthated form of the poly((1.fwdarw.3) glucan). The solutions so formed have been shown to be useful for solution spinning into fiber of poly((1.fwdarw.3) glucan) when the spun fiber is coagulated in an acidic coagulation bath. The fibers so produced exhibit desirable physical properties. The poly((1.fwdarw.3) glucan) employed was synthesized by fermentation.

An alginate fiber and a preparation method thereof are provided. The preparation method of the alginate fiber includes: S10: preparing a spinning solution with a raw material including sodium alginate; S20: extruding the spinning solution obtained in S10 into a solidification bath to allow solidification molding to obtain a primary fiber; S30: drawing and water-washing the primary fiber obtained in S20 to obtain an alginate fiber; and S40: soaking the alginate fiber obtained in S30 in a finishing agent to allow a post-treatment, where at least one of the raw material in S10, the solidification bath in S20, and the finishing agent in S30 includes a five-membered cyclic quaternary ammonium salt polymer. The alginate fiber obtained above has a high dye uptake, a small fiber strength loss, and a high soaping fastness.
