  fiber pull out
In a composite material reinforced by short random fibers, damage results from different elementary failure mechanisms such as matrix microcracking, fiber pull out, failure of the fiber/matrix interface, failure of fibers, etc.
      
Furthermore, residual fiber pull out of the fragmented fibers aids in additional load carrying capability.
      
Single fiber pull out test was applied to determine the interfacial shear strength of carbon-polyimide.
      
Some fibers are broken, but predominantly fiber pull out occurs.
      
Secondary nucleation or growth was investigated in the fiber pull out device.
      


Energy dissipation, i. e., the work of fracture, and the fracture mechanisms of fibre reinforced composite have been discussed. The work of fracture for composite materials is different from that of a monolithic brittle solid which consists of the surface energy only. The total work of fracture is associated with fibre pull-out, dcbonding, post debonding frictional work and surface energy, by which the fracture toughness of composite is characterised.

本文讨论了纤维增强复合材料断裂时的能量消耗即断裂功及其机制。单质固体的断裂功仅仅是由表面能决定的,而复合材料的断裂功不同于单质脆性固体,其总的断裂功与以下四方面有关:①纤维的拉出,②脱粘,③脱粘后的摩擦功,④表面能,复合材料的断裂韧性可以用断裂功来表征。

In this paper,the reinforcing effect, the stretching and compressing destructive mechanism in the polyurethane foam plastics reinforced by short cutting glass fibres have been studied. The results show that the reinforcing effect is best when the fibre length is 12 mm and the fibre content is 6 wt%. The stretching intensity, the compressing intensity and the compressing modulus are increased by 75%, 25% and 30%, respectively. When the foam reinforced by fibres is stretched, the cracks are produced and the...

In this paper,the reinforcing effect, the stretching and compressing destructive mechanism in the polyurethane foam plastics reinforced by short cutting glass fibres have been studied. The results show that the reinforcing effect is best when the fibre length is 12 mm and the fibre content is 6 wt%. The stretching intensity, the compressing intensity and the compressing modulus are increased by 75%, 25% and 30%, respectively. When the foam reinforced by fibres is stretched, the cracks are produced and the cracks spread. They may stop spreading (as the stress is low) or may present deflection (as the stress is high) when the cracks meet fibres. Different destructive shapes (the fibres are pulled out, broken and so on) may occur when the foam is destroyed. The prop of the foam structure may be crooked, twisted and out of shape when the foam reinforced by fibres is compressed destructively. It leads to rupture of foam wall, losing stability of prop and destruction of material.

研究了用短切玻璃纤维对硬质聚氨酯泡沫体的增强效果及拉伸、压缩的破坏行为。结果表明当纤维长为12 m m 时,6 w t% 纤维含量的增强效果为最好,可以使泡沫体的拉伸强度提高75% ,压缩强度提高25% ,压缩模量增加约30% 。纤维增强的泡沫体拉伸产生的裂纹扩展时,遇到纤维可能终止扩展(应力不大时),也可能发生偏转(应力较大时);泡沫破坏时,可能出现纤维拉出、拉断等不同的破坏形式。增强泡沫体在压缩破坏时,主要是泡沫结构的支柱弯曲、扭转变形引起泡壁破裂和支柱失稳,并导致材料的破坏。

A specially designed mold was employed to prepare single fiber Nicalon/glass composite specimens for pull out test.The quasi linear dependence of Raman shift upon fiber strain was first used to measure the residual thermal strain along the fiber axis.Then the same dependence was used to determine the fiber strain during pull-out test.Finally the distribution of striain along the fiber axis was converted to the distribution of interfacial shear stress.The results show that for the given experimental conditions...

A specially designed mold was employed to prepare single fiber Nicalon/glass composite specimens for pull out test.The quasi linear dependence of Raman shift upon fiber strain was first used to measure the residual thermal strain along the fiber axis.Then the same dependence was used to determine the fiber strain during pull-out test.Finally the distribution of striain along the fiber axis was converted to the distribution of interfacial shear stress.The results show that for the given experimental conditions the length of interfacial stress transfer is 0.18 mm and the maximum ISS is located at x =0.11 mm.

使用一专门设计的模型制作了碳化硅(Nicalon)/玻璃复合材料单纤维拉出试样。利用纤维拉曼峰波数偏移与纤维所受应变的近似线性关系,首先测定纤维热残余应变的分布,随后对伸出玻璃基体外的纤维段施加给定的拉伸应变,沿纤维轴向用拉曼光谱术逐点测定基体内外纤维的应变,最后依据力平衡原理将应变分布转换为界面剪切应力沿纤维轴向的分布。结果表明:在给出的实验参数下,界面传递应力长度为0.18mm,最大界面剪切应力的位置在x为0.11mm处。
