The invention provides a carbon fiber felt reinforcement inorganic polymer matrix composite and a preparation method of the carbon fiber felt reinforcement inorganic polymer matrix composite, and relates to an inorganic polymer matrix composite and a preparation method of the inorganic polymer matrix composite, in particular to the carbon fiber felt reinforcement inorganic polymer matrix composite and a preparation method of the carbon fiber felt reinforcement inorganic polymer matrix composite. The problems that an existing inorganic polymer material is poor in mechanical performance and low in toughness and the operation for adding short carbon fiber is complex are solved. The product is prepared through inorganic polymer material pulp and carbon fiber felt. The inorganic polymer material pulp is prepared through potassium hydroxide, silica sol and aluminosilicate powder. The method includes the steps of firstly, preparing the inorganic polymer material pulp; secondly, washing the carbon fiber felt; thirdly, preparing a prefabricated material blank; fourthly, preparing the carbon fiber felt reinforcement inorganic polymer matrix composite. The method is simple in process, low in cost, environmentally friendly and capable of being use for large-area preparation, and the prepared composite is good in mechanical property and wider in application range.

The invention relates to a method for manufacturing a fiber reinforced plastic plate type spring. The method comprises the following steps of prepreg preparing, clipping, layering, heat forming and post-processing. The implementation process includes clipping a unidirectional fiber prepreg and a bidirectional fiber prepreg into needed shapes, and attaching the clipped unidirectional fiber prepreg and the bidirectional fiber prepreg on a die to be manufactured into a preformed body according to a set layering mode. The preformed body can be one layered through one or more of the unidirectional fiber prepreg and the bidirectional fiber prepreg. The preformed body can be manufactured into a needed composite material plate type spring through lamination forming, post heat treatment and mechanical processing. Heat forming of plate springs is controlled through temperature, time and pressure. The composite material plate type spring has the advantages of being high in strength, light in quality, fatigue resistant, good in heat stability and small in deformation.

The invention discloses a tungsten-based plasma facing material and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing tungsten powder and tungsten fiber by a powder mixing method which does not damage the tungsten fiber; and sintering to prepare a bulk fiber toughened tungsten-based material by a hot isostatic pressing process. The tungsten powder is one of pure tungsten powder, tungsten-rhenium alloy powder, and tungsten powder doped with carbide and oxide; and the tungsten fiber is a pure tungsten wire, a tungsten-rhenium alloy wire or the like. The tungsten-based plasma facing material has the advantages of high thermal conductivity, high melting point temperature, low sputtering yield, low hydrogen isotope retention and low vapor pressure, as well as low cost and greater toughness.

The invention discloses a tipping paper base paper with functions of clearing away heat and relieving alcohol, which is characterized in that it is prepared from the following raw materials in parts by weight: 3-4 parts by weight of ashweed, 1-2 parts of nigella seed oil, and 41 parts by weight of pomegranate pulp -46, cork pulp 52-55, pterygium 2-4, mannitol 1-1.5, Hovenia dulcis 1-2, taurine 0.5-0.7, activated clay 3-4, iron oxide yellow 1-2, Carboresin 2-3, Ammonium Bicarbonate 1-1.6, Calcium Peroxide 2-2.5, Calcium Propionate 1-2, Auxiliary 1-2, appropriate amount of water; the present invention adds Pterocephala clearing heat and detoxifying, Hovenia dulcis Alcohol poisoning, the production of tipping paper base paper has certain health effects, suitable for social use, adding additives, not only can increase the amount of tar adsorption, but also has a natural fragrance, fresh and pleasant, reducing bad breath, and the fiber distribution of the product of the present invention Uniform, small fluctuations in thickness, tightness, air permeability and other indicators, easy to print.

The invention discloses raw tipping paper with high quality and good breaking resistance degree. The raw tipping paper is characterized by being prepared from following raw materials in parts by weight: 45-48 parts of pine pulp, 53-56 parts of fluff pulp, 4-6 parts of phoenix tree barks, 1-2 parts of gelonium, 2-3 parts of polyvinylpyrrolidone, 1-2 parts of alums, 2-3 parts of calcium carbonate, 2-4 parts of a zeolite molecular sieve, 1-3 parts of silicone rubber, 0.8-1 part of beta-carotene, 1-2 parts of lithopone, 2-3 parts of carboxymethylcellulose, 1-2 parts of an auxiliary agent and suitable amount of water. According to the raw tipping paper, prepared phoenix tree bark fibers are added into papermaking pulp so that a product has white fibers which are uniformly distributed; a paper sheet is firm and durable, has good breaking resistance degree and is smooth and fine; the raw tipping paper has a good printing ink leveling performance; the auxiliary agent is added so that the raw tipping paper has a certain adsorption effect, has a pleasant aroma and can be used for improving the spicy taste of smoke.

The invention relates to a glue-bonding-free composite filter material manufacturing device and an application method thereof. The device mainly comprises a heat-resistant fiber filter material roller, a filter material heating component, a short fiber paving component, a hot rolling roller, a guiding roller, a cooling water tank, a composite filter material roller, and an oven. The application method comprises the following steps: making a heat-resistant fiber filter material go through the heating component so as to heat the surface of the filter material to a certain temperature; rapidly paving the short fibers on the surface of the heat-resistant fiber filter material through feeding the short fibers into a groove, a gear-shaped conveying belt, and the short fiber paving component, making the short fibers be melt and attached on the filter material; then making the filter material coated by the short fibers go through the hot rolling roller so as to strengthen the adhesion effect; then making the filter material go through the guiding roller which can immediately soaking the composite filter material into the cooling water so as to make the composite filter material be tightly adhered, and finally placing the wet composite filter material in the oven to carry out a drying treatment so as to obtain the finished composite filter material. The composite filter paper is prepared through a glue-bonding-free technology, the filter material void fraction is largely improved, the one-time service life and filter efficiency of the filter material are increased, and the manufacturing method of the filter material has the advantages of reasonable design, high production efficiency, simple technology, and even fiber thickness of composite layer.
