  composites
In this paper, the so-called approximate convexity and concavity properties of generalized Gr?tzsch ring function μα(r) by studying the monotonicity, convexity or concavity of certain composites of μα(r) are obtained.
      
Preparation and properties of polymer and quantum dot composites
      
The prepared composites were characterized with UV-Vis, PL, TEM, FTIR, CLSM and conductance titration etc.
      
Spectra results indicated that there existed interactions between nanocarbon and the polymethyl methacrylate (PMMA) matrix, which was consistent with the decrease in glass transition temperature of the composites with increase of carbon content.
      
TEM images revealed that a carbon encapsulated core/shell structure was formed in the composites, which could ensure good dispersion of carbon nanoparticles within the PMMA matrix.

The theory of tensile strength of composite materials are considered In eluded are analyses of tensile strength of fibers, fiber boundles and the different failure machanisms of composites.Most of the reinforcing fibers presently in use are known fo be brittle with a wide scatter in their tensile strength values, and a statistical approach is then called for the discription of strength characteristics of fiber, fiber bundles and conposite materials. In this paper, the probability desity funcfion to present the strength distribution of a single fiber is of the weibull form and that for large bundles the Gaussian type. The above information is ultilized to form theoretical models of composite strength. Both the cumulative weaking model with or without stress concentration are considered.Most recent works are summerized. Experimental data are compared to the analytical results and review be given in this study.

本文介绍复合材料的轴向拉伸强度的理论。涉及纤维、纤维束的强度和复合体的拉伸破坏型式分析。 常用纤维加劲材料,大都是脆性纤维。脆性纤维强度变化幅度很大,为此纤维复合材料,须用概率论方法来分析。本文按纤维强度分布为Weibull型,纤维束强度分布为Caussian型,而后采用环链模型理论,就考虑和不考虑应力集中来分析复合体强度。 本文中介绍了新近的科研成果,有理论与实验的验证材料和评论。

This paper has evaluated the fractographic features from wc-steel composite structures,obtained by scanning electron microscopy from the alloy I WC 50% C 0.25 %,Cr 0.5%,Mo 0.25%.It will be shown that those fractures are similar to D-B fractographic features in conventional composite materials,and the Matrix is also similar to common steels.The larger dimples are obviously centered around WC particles.Sometimes cleavage fractures originate at the WC particle surface. Through the examination we have found that most cracking paths are through the interfaces of WC particles and the matrix.According to different conditions of heat treatment,we can get the dimple fractures,quasi - cleavage fractures or TTS fractures. If you want to improve the mechanical properties of the alloy,it is important to increase the ductility of the matrix and improve the wetting characteristics of the interfaces of WC-steel composites,

采用扫描电镜研究了WC——钢复合结构的断口形态。试验用的合金为:WC 50%,C 0.25%,Cr 0.5%,Mo 0.25%。结果证实此类断口与普通复合材料的韧——脆性断口相似,而基体的断口与普通钢的断口相类似。很明显,断口中的大韧窝是以WC颗粒为中心的。有时在WC颗粒表面出现解理断口。通过试验发现裂纹扩展途径主要是沿着WC与基体的界面进行。通过不同的热处理,可以获得韧窝断口,准解理断口或撕裂型断口。为了提高此类合金的机械性能,改善基体的韧性与WC——钢界面的浸润性是十分重要的。
