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。

A study of the carbon/epoxy composite with 0° ply and qqqqq 45 ° ply specimens (unnotched, with single edge notch and with double edge notches normal to the load) was carried out under tensile testing. Results were compared with each other. Strain extensometers were used to record load-displacement curves automatically, from which the moduli and ultimate stresses were determined. Acoustic emission and high speed photography were used to observe and record the process of failure. Fracture surface was examined...

A study of the carbon/epoxy composite with 0° ply and qqqqq 45 ° ply specimens (unnotched, with single edge notch and with double edge notches normal to the load) was carried out under tensile testing. Results were compared with each other. Strain extensometers were used to record load-displacement curves automatically, from which the moduli and ultimate stresses were determined. Acoustic emission and high speed photography were used to observe and record the process of failure. Fracture surface was examined by scanning electron microscope.Results of experiment show that when notched specimens are axially loaded in tension, crack does not propagate along the direction of notch. Instead, it propagates along the fiber direction. This demonstrates notch insensitivity of fiber reinforced composites. The ultimate strength of notched specimens are about the same as that of the specimens without notch (based on net cross sectional area). The notch appears to have no substantial effect on the stresses in the un-notched portion. Fracture toughness of the experimental material was estimated and the failure mode was discussed.

本文对碳纤维增强环氧复合材料0°和±45°铺层带边缘缺口试件进行了拉伸破坏实验研究。结果表明:带有垂直于载荷方向边缘缺口的此种碳纤维增强复合材料受拉伸时,裂缝不是沿缺口长度方向扩展,而是沿纤维方向产生并扩展,缺口的存在基本上不影响其余无缺口部分的应力。对缺口不敏感特性与破坏模型进行了讨论。这种材料的破坏机理与各向同性材料相比具有明显的差别。

The fracture characteristics of fiber reinforced materials subjected to off-axis tensile load are observed to indicate that there is a certain angle in which direction the off-axis tensile fracture approximates well to pure shear fracture. A method of optimal angle for off-axis tensile test is then provided for determination of the shear stress-strain characterization of composites. Other testing methods, for example, [±45°]s off-axis tensile test suggested by Rosen or/and 10°off-axis tensile test suggested...

The fracture characteristics of fiber reinforced materials subjected to off-axis tensile load are observed to indicate that there is a certain angle in which direction the off-axis tensile fracture approximates well to pure shear fracture. A method of optimal angle for off-axis tensile test is then provided for determination of the shear stress-strain characterization of composites. Other testing methods, for example, [±45°]s off-axis tensile test suggested by Rosen or/and 10°off-axis tensile test suggested by Daniel and Chamis can be regarded as the specific case of,this method. The method provided in this paper, therefore, is seemed to be more perfect and has more general significance. Tests with various off-axis angles have been performed and the results are in good agreement with those predicted theoretically. Thus, the validity of this method is verified.

本文通过对偏轴拉伸下破坏特点的分析,说明在特定最优偏轴角下的偏轴拉伸破坏十分接近于纯剪破坏,提出了测定完整(ι_(12)~γ_(12))曲线的最优偏轴角拉伸试验方法。它概括了Chamis和Sinclair~([1]-[3]的10°偏轴和Rosen~[4]的45°偏轴拉伸方法,使偏轴拉伸法更完善并具有更普遍的意义。通过对1:1玻璃布/环氧、4:1玻璃布/环氧、7:1玻璃布/环氧三种玻璃钢的偏轴拉伸试验,得到与理论分析相当一致的结果,验证了这一方法的可靠性。
