【摘要】：纖維增強(qiáng)復(fù)合材料是由增強(qiáng)體纖維材料,如玻璃纖維,碳纖維等,與基體材料經(jīng)過濕法纏繞,模壓或拉擠等成型工藝而形成的復(fù)合材料。因其具有高比強(qiáng)度、比剛度等特點,被作為結(jié)構(gòu)工程材料廣泛應(yīng)用于航海、航空航天、汽車、體育器械等重要領(lǐng)域。纖維和基體相互接觸部位因為發(fā)生物理或化學(xué)反應(yīng)會形成界面,界面是纖維和基體之間的一個過渡區(qū)域,其力學(xué)性質(zhì)和基體、纖維都有所不同。纖維和基體之間的界面性質(zhì)無法直接測量,一般用纖維和基體材料之間的粘結(jié)強(qiáng)度來表征界面性質(zhì)。纖維和基體的粘結(jié)強(qiáng)度對纖維增強(qiáng)復(fù)合材料的力學(xué)性能起著非常重要的作用,粘結(jié)強(qiáng)度低,會影響材料的最終力學(xué)性能。因界面的表面積非常大,復(fù)合材料的微細(xì)觀結(jié)構(gòu)缺陷,例如小孔、雜質(zhì)和微裂紋,在界面層位置比較多,這些結(jié)構(gòu)缺陷會導(dǎo)致應(yīng)力集中,降低界面的載荷傳遞效率,最終影響纖維增強(qiáng)復(fù)合材料的宏觀力學(xué)性能。本文發(fā)展了纖維束復(fù)合材料的測試技術(shù),用以模擬常規(guī)單向?qū)雍习宓臋M向拉伸試驗和剪切試驗,對T700碳纖維增強(qiáng)E51環(huán)氧樹脂基復(fù)合材料的界面粘結(jié)強(qiáng)度進(jìn)行了試驗研究。通過對比纖維束復(fù)合材料和單向?qū)雍习宓脑囼灲Y(jié)果,以及其相應(yīng)的破壞形態(tài),建立纖維束復(fù)合材料測試結(jié)果與其模擬的單向?qū)雍习宓牧W(xué)試驗結(jié)果的關(guān)系�；谠摮晒�,可以實現(xiàn)用較為簡單的纖維束復(fù)合材料試驗的結(jié)果評估或預(yù)測相應(yīng)的單向?qū)雍习宓暮暧^界面力學(xué)性能。
[Abstract]:Fiber reinforced composites (FRC) are composites formed by fiber reinforced materials, such as fiberglass, carbon fiber, and matrix materials, which are formed by wet winding, moulding or pultrusion. Because of its high specific strength, specific stiffness and other characteristics, it is widely used as structural engineering materials in navigation, aerospace, automobile, sports equipment and other important fields. The interface between fiber and matrix is formed because of physical or chemical reaction. The interface is a transition region between fiber and matrix, and its mechanical properties and matrix are different from each other. The interfacial properties between fiber and matrix can not be measured directly. Generally, the bond strength between fiber and matrix is used to characterize the interfacial properties. The bond strength between fiber and matrix plays an important role in the mechanical properties of fiber reinforced composites. The low bond strength will affect the ultimate mechanical properties of the composites. Because the surface area of the interface is very large, the microstructural defects of the composite, such as pores, impurities and microcracks, are more in the interfacial layer. These structural defects will lead to stress concentration and reduce the load transfer efficiency of the interface. Finally, the macroscopic mechanical properties of fiber reinforced composites are affected. In this paper, the testing technique of fiber bundle composites has been developed to simulate the transverse tensile test and shear test of conventional unidirectional laminates. The interfacial bond strength of T700 carbon fiber reinforced E51 epoxy resin composites has been studied experimentally. By comparing the experimental results of fiber bundle composites and unidirectional laminates and their corresponding failure patterns, the relationship between the test results of fiber bundle composites and the mechanical test results of unidirectional laminated plates simulated by fiber bundle composites was established. Based on this result, it is possible to evaluate or predict the macroscopic interfacial mechanical properties of unidirectional laminates with the results of simple fiber bundle composite test.
