Effect of gravity on resin flow behavior by VARI process Chenhui Zhao, Guangcheng Zhang Department of Applied Chemistry, School of Natural and Applied Science, Northwestern Polytechnical University, Xi’an, 710129, P.R.China zhaohui18201@163.com, zhangguc@nwpu.edu.cn Keywords: VARI; foam sandwich; foam grooves; resin flow behavior Abstract：The resin flow behavior in vacuum assisted resin infusion molding process (VARI) of foam sandwich materials was studied through visualization flow experiments.
Because VARI process is usually used to produce the large-scale composite structures such as ships, refrigerated containers and bridge deck [6], effect of resin gravity on resin flow behavior can not be neglected[7-8].

It is advantageous that the flexibility of these materials can be controlled by changing the mixing ratios of the organic and inorganic components and that the silanol groups can be incorporated in the structure.

To prevent wood’s structure damaging, wood should not be absolute dry.

On the other hand, all of these data above indicate that not only the molecular weight increased, make copolyester structure be consistent with the addition ratio, but also the generating of blocky alignment decreased by addition of acetic anhydride.

QSAR Models to Predict Effect of Concentration on the Adsorption of Phenolic Compounds onto XAD-4 and ZH-01 Yunlan Gua, Zhenxing Lib, Zhenghao Feic*, Gencheng Zhangd Jiangsu Provincial Key Laboratory of Coastal Wetland Bioresources and Environmental Protection,Institute of Applied Chemistry & Environmental Engineering, Department of Chemistry,Yancheng Teachers university, Jiangsu 224051, China aanyangkongweize@163.com, blzx76@126.com, cfeizhenghao@163.com,dzgchx406@163.com Keywords: Phenolic compounds, Adsorption capacity, DFT, QSAR.
The utility of this concept has been demonstrated by incorporating concentration as a parameter in quantitative structure-activity relationship (QSAR).

However, for the large model, except the change of Si-O-Si bond angle, its structure has no other significant changes.
As shown in Fig. 9(a) and (c), it can be summarized from the O-Si-O BAD of 50 Å and 150 Å models that there arises an irreversible change of the structure of the 50 Å model while the structure only slightly changes and resumes finally after the model failures for the 150 Å model.
In future study, we will discuss how porous structure would affect the mechanical property in micro-scale and nano-scale along with structure of diatom.
