    摘要： A method for making a fiber-reinforced composite comprises dispensing a reactive liquid into a mold. The mold comprises fibers and a single-component activator on the fibers. The reactive liquid comprises a cyclic olefin, and the mold comprises fibers and a single-component ROMP activator on the fibers. Composites formed by the method may have high fiber densities.

    摘要： A curing composition comprises a zeolite molecular sieve containing in the absorbed state an organic peroxide, an organic amine containing at least 3 carbon atoms, an aldehyde, a thiazole, a thiocarbamate or ammonia. The actual curing agent is desorbable from said molecular sieve on heating to the curing temperature of the material to be cured. Exemplified curing agents are di-tertiary-butyl peroxide, methyl ethyl ketone peroxide, diethylene triamine, piperidine, diethanolamine, diethylamine, propylene diamine and di-n-butylamine. An extremely active accelerator containing mercaptobenzothiazole and di-butyl ammonium thiocarbamate can be added to rubber compounds in the presence of a zeolite with safety.ALSO:A curing composition comprises a zeolite molecular sieve, (i.e metal-aluminium-silicates) containing in the adsorbed state an organic peroxide, an organic amine containing at least 3 carbon atoms, an aldehyde, a thiazole or a thiocarbamate or ammonia. The actual curing agent is desorbable from said molecular sieve on heating to the curing temperature of the material to be cured. Exemplified curing agents are ammonia, paraformaldehyde, di-tertiary-butyl peroxide, methyl ethyl ketone peroxide, diethylene triamine, piperidine, diethanolamine, diethylamine, propylene diamine and di-n-butylamine. An extremely active accelerator containing mercaptobenzothiazole and di butyl ammonium thiocarbamate. can be added to rubber compounds in the presence of a zeolite with safety. Resins and rubbers cured are co-polymers of butadiene and acrylonitrile, co-polymers of butadiene and styrene, natural rubber, copolymers of butadiene and an acrylic ester, a resorcylic end-blocked polysiloxane, unsaturated polyesters containing an unsaturated grouping such as a maleic ester group in a solution of a styrene monomer, phenolformaldehyde resins, neoprene, epoxy resins, nitrile rubber, butyl rubbers, and polyvinyl chloride/polyethylene glycol acrylic diester mixtures. Additional agents which may be incorporated into the composition for curing are carbon black fillers, zinc oxide, sulphur, zinc stearate, N-cyclohexyl-2-benzothiazole sulphenamide and dioctyl phthalates. Specifications 777,232 and 777,233 are referred to.

    摘要： An aerogel carrying an active material, and a composite of a hydrogel and the aerogel are provided. The method for preparing the composite according to the present invention comprises the steps of preparing a plurality of aerogel particles having an active material in the pores, preparing a polymer solution in which a polymer is dissolved in a water-soluble solvent, preparing an aerogel/polymer dispersion by homogenizing after mixing the aerogel particles in the polymer solution, and preparing an aerogel/hydrogel composite carrier by mixing the dispersion with a crosslinking agent solution. According to the present invention, by producing a hydrogel composite in which a plurality of aerogel particles is distributed, a complex carrier in which oil and moisture can be carried simultaneously without any surfactant can be provided. Furthermore, a composite carrier having improved properties such as low density, high strength, high component content and stable desorption can be prepared.
