Environmental-Friendly Soy Protein Isolate/Poly(Vinyl Alcohol) Blend Films: Biodegradation Behaviors
Online since: December 2010
Authors: Jun Feng Su, Wen Long Xia, Shan Shan Wang
In general, similar to other protein (wheat, corn) films, SPI films provide lower mechanical properties and higher moisture sensitivity.
Moreover, literature [2] has confirmed that SPI films without other secondary components do not show good mechanical and barrier properties.
These blend films showed enhanced mechanical properties comparing to pure SPI films.
As a kind of protein-based packaging film, it is well known that the appearance, moisture sensitivity and mechanical properties will be important characters greatly affecting consumer acceptance of such protein-based films.
These results indicated that the color was greatly affected by the factors of pH value, cross-linkage degree, plasticizer addition, thermal treatment, fabrication process and weight contents of blends [6].

Introduction
The factors affecting the slope stability are numerous.
But the influencing degrees of these factors vary with different slopes.
When the test factors and factor levels are more, there is some difficulty for the method.
The physical and mechanical properties of rock-soil are determined by the surrounding natural environment.
The thirteen influencing factors can be seen from table 1.

Yarn tension during weft insertion is one of important factors which affect fabric properties.
Moreover, weft tension has a direct influence on fabric properties such as air permeability, abrasion resistance, tensile strength, etc [2].
Although numerous factors acting on weft tension have been discussed, still many problems are waiting to be solved.

Fluctuations in material properties.Different grade pipeline steel plates have different mechanical properties and present significant difference in forming performance, process parameters and forming shape of the parts.
Table 1 shows mechanical properties fluctuations for X70 in the different volume.
So it is a prerequisite to investigate the impact of the mechanical properties on the springback to obtain high-quality qualified pipe.
Experimental factors levels were shown in Table 2.
RBF network can be used to study and deal with the relation between multiple factors and the response variable.

Mechanical performance of CF/PEEK composites
Carbon fiber can greatly improve the mechanical properties of PEEK composites.
However, there are various factors can affect the mechanical properties of CF/PEEK.
They analyzed the effect of molding press parameters on the mechanical properties of CF+G/PEEK composite material.
They found that the mechanical properties are improved if higher forming temperatures are used, but the increase is most dramatic in mode I delamination behavior and the improvement in mechanical properties with forming temperature is due to an increase in interfacial strength between fibre and matrix.
The evaluation of the tensile properties and the short beam shear strength of the consolidated samples suggest that successive consolidations can affect the mechanical behavior of the CF/PEEK composites.
