Abstract: The paper analyze development process of the advanced resin matrix composite materials forming technology, that is low pressure molding, pultrusion process, molding, filament winding forming process, placement molding process, molding process of RTM, and analyze the key technology in the development process, to study the evolvement of advanced composite material molding process, so as to explore the future development direction of forming resin based composite material technology.

Abstract: Expanded graphite is a new porous carbon-based adsorption material with well-developed pore structure and large adsorption capacity for nonpolar molecules pollutants. In this paper, research of the expanded graphite as novel functional carbon material in the fields of environmental remediation of oil pollution and wastewater treatment are reviewed. Based on this, the problems that exist in the current research on expanded graphite in treatment of environmental pollution are analyzed, and the main development trend of research on expanded graphite in the field of water environmental protection is put forward.

Abstract: An important and basic issue of compound material surface analysis was raised in this paper, that was, the picking basic element which that material microstructures were well characterized according to the research subject of material. Here, the five kinds of basic element were proposed for picking, they were separately ellipse, regular triangle, rectangle, square and circle. At first, the counting methods and rules of area radio base on elements and pictures, and the formula of the merging difference was introduced, then block experiment design in modern statistics was used to pick among the five elements. At last, through experiment and analysis, the result of picking was that ellipse element was most appropriate one among five elements. Meanwhile, it was pointed in this paper with regard to the area radio of picture based on element that the approaching extent of the ellipse was most suitable among five elements.

Abstract: Based on the elliptic element model, the new sorting method on the same pattern compound materials was given in this paper according to the pictures obtained by electronic microscopy systems on the surfaces. Here, the block design combined with variance analysis was introduced to sort the compound materials that contained that the copper-base mingled with graphite, silica and other non-pronounced components. Here, the five kinds of the same pattern compound materials were proposed for sorting, only the graphite distribution was considered and their mixture ratios of components were separately 10%, 15%, 20%, 25%, 30%. At last, through experiment data and statistical analysis, the result of sorting was basically corresponding to the above mixture ratios of components.

Abstract: The author had used salivation method to prepareQuercetin-ornidazole-chitosan composite material (QOCCM) and then used this film to the treatment for the rat model of oral ulcer. and finally found that it can promote the healing of ulcers. In order to investigate the mechanism of action in the treatment of oral ulcers, we prepare Quercetin-ornidazole-chitosan complex solution, and then used the application of carrageenan induced paw edema and croton oil-induced mouse ear swelling to observe its anti-inflammatory role, application of hot plate method to observe the analgesic effect of inflammatory and evaluate the effects of chitosan composite materials.

Abstract: With the drug-loaded chitosan as film forming materials, use salivation method to prepare Quercetin-chitosan composite film of oral ulcer and use this film to the treatment for the rat model of oral ulcer. To study the therapeutic effect for oral ulcer of the Quercetin-Chitosan composite film by measuring the area, the volume and the healing speed of the ulcer, observing edema and congestion degree of ulcer surface, and detecting the pathological changes of ulcer tissue by HE staining.

Abstract: Accoding to the current situation of deck surfacing with Epoxy asphalt and its development in China and abroad, this paper has analyzed the feature of the function of Epoxy asphalt used on surface pavement of cement concrete bridge through analyzing the physical and chemical properties of Epoxy asphalt and further testing the superiority of Epoxy asphalt in the road construction.

Abstract: Harmful algal blooms have long been an issue worldwide owing to their adverse effects on drinking water treatment processes as well as drinking water quality. In this paper, chitosan-bentonite compound material was prepared by the supporting of chitosan on pillared bentonite and used for removal of harmful algae from water. The results showed that the compound material was effective for the removal of cyanobacterial Microcystis aeruginosa.
