    How to toughen an epoxy resin system for glass and carbon fiber composites is investigated.The system consists of butadiene-acrylonitrile rubber with random carboxyl groups(CTBNX),epoxy resin of diglycidyl ether of biphenol A(DGEBA)and 2-ethyl-4-methylimidazol.The main objectives of this research are:(1)to toughen epoxy resins with commercially available elastomer CTBNX;and(2)to determine the effectiveness of this CTBNX-modified epoxy resin system in fiber reinforced composites.The authors'previous studies(4,5)show that the toughened epoxy resin can be prepared with CTBNX or CTBNX-bisphenol A to form a two-phase system.The toughened epoxy resins exhibit significant improvements over the unmodified ones in impact strength,modulus of toughness(area under the stress- strain curve)and fracture surface energy,by as much as 2 to 10 times,0.5 to 11.5 times and 1 to 4 times respectively.This paper presents the research results of the effects of matrix toughness on the crack resistance,impact strength and mechanical properties of unidirectional glass fiber composites and describes the technique of measuring the fracture toughness KQ of fiber composites.Test results show that:1.In the unidirectional glass epoxy composites,the increases of transverse and longitudinal impact strengths,fracture surface energy and candidate stress intensity factor KQ depend mainly on enhancement of the resin matrix toughness,but are not so large as in bulk resins and only modest,though still the increases obtained are significant.Wtih enhancing the matrix toughness,short beam interlaminar shear strength and all transverse mechanical properties except tensile modulus of composites increase,while all longitudinal mechanical properties and flexural properties change inappreciably.2.The use of double edge notched tension specimen(DEN)for determining fracture toughness of unidirectional fiber composites is recommended.

    以双酚A型环氧树脂——无规羧基丁腈橡胶——2-乙基-4-甲基咪唑体系为代表,考察了树脂基体的韧性对单向玻璃纤维复合材料力学性能的影响。试验结果表明:随着树脂基体韧性的提高,所得复合材料的伉断裂性能相应地增加,但提高的幅度较树脂基体本身韧性的提高值小;复合材料的短梁剪切强度、除拉伸模量以外的横向力学性能也随树脂基体韧性的增加而提高,而弯曲性能及纵向力学性能受树脂基体韧性的影响不明显。

    The tensile failure behaviours of six multi-ply carbon/epoxy composites ([0/90]s, [±45]s, [30/60] and three kinds of carbon cloths) have been investigated. Acoustic emission technique was employed in monitoring their damage process together with microscopical observation.The occurrence of acoustic emission weighted ringdown signals indicate the release of strain energy at the initial damage of the composite materials. Generally, for [±45]s, [30/60] ply and transverse carbon cloths specimens whose stress-strain...

    The tensile failure behaviours of six multi-ply carbon/epoxy composites ([0/90]s, [±45]s, [30/60] and three kinds of carbon cloths) have been investigated. Acoustic emission technique was employed in monitoring their damage process together with microscopical observation.The occurrence of acoustic emission weighted ringdown signals indicate the release of strain energy at the initial damage of the composite materials. Generally, for [±45]s, [30/60] ply and transverse carbon cloths specimens whose stress-strain curves all have an inflection, initial damage acoustic emission signals occur al this location, for most of them in the vicinity of 40% ultimate strength and maximum strain. Their maximum weighted ringdown counts are of the same order of magnitude, but their total A. E. weighted ringdown counts differ magnificantly. This shows that the total energy of damage released is quite different for the differently plied composites. Due to deformation and damage, the A. E. pattern of the carbon cloth specimen demonstrates continuous energy release, but that of bidirectionally plied specimen shows discontinuity. The A. E. signals of cross-ply specimen occur at regular intervals with little change in the amplitudes of the weighted ringdown signals. This indicates homogeneous orthotropy for [0/90]s specimens. However, for [±45]sand [30/60] specimens energy release is concentrated at the final stage.

    本文对六种多向铺层的碳纤维增强环氧复合材料的拉伸破坏性能进行了研究,并采用声发射技术监测其损伤扩展过程,分析了它们的破坏机理。 新型的高性能碳纤维增强环氧复合材料应用于宇航、机械及体育器具等,由于工作条件及受力情况是复杂的,采用多向铺层才能满足受拉、压、弯、剪、扭等不同载荷的分别组合,具体铺层设计要针对主要承力情况来确定。多向铺层复合材料的损伤破坏比单向铺层的情况复杂,更需要采用试验的手段来研究它们的力学性能和破坏机理。在非破坏性测试中声发射技术的特点在于能够配合加载装置在进行试验过程中检测并记录复合材料的破坏过程,而且不移动探头的位置即可监测材料的较大区域,因此应用愈来愈多。声发射技术是利用材料或构件受力变形或损伤过程中应变释放产生弹性波这一原理来检测材料的缺陷、退化和破坏,评定材料的性能。声发射技术可以检测复合材料的剪切破坏及拉伸屈服破坏、分层及纤维断裂、粘接强度等。 本工作对六种多向铺层碳/环氧复合材料(包括0/90、±45°、30/60和三种碳布)进行拉伸试验,确定了它们的强度、模量、最大应变率及泊松比,给出六种不同铺层的应力应变关系以及声发射信号量的关系。采用声发射技术配合显微镜观测手段分析不同铺层...

It was found that a dense polymeric interface layer would be formed on the surface of solid fillers due to the interaction between paniculate filler surface and epoxy matrix. The properties of interface layer are different from that of matrix. These composites are considered as three-element systems, consisting of filler, interface and bulk resin.

    本文对氧化铝(Al_2O_3)、氟化钙(CaF_2)和玻璃微珠颗粒填充环氧基(E51环氧—胺固化体系)复合材料的密度和动态力学性能进行了研究。结果发现由于颗粒填料表面和环氧基体的相互作用,从填料表面开始形成了一层致密的聚合物界面层。它的性质与本体树脂有明显的差别。把填充复合材料看成由填料、界面层和树脂本体组成的三元体系,从“临界填料含量”概念出发,求得了界面层的密度,界面层的厚度和界面层的体积分数。
