“…For the metal layer, lightweight alloys of aluminium [5], titanium [1,6] and magnesium [7] have been employed. For the composite layer, various types of reinforcing fibres including aramid [8], carbon [9] and glass [10] fibres in a thermosetting or a thermoplastic matrix have been investigated.…”

High-velocity impact deformation and perforation of fibre metal laminates

The quasi-static flexural and impact performance, up to projectile impact velocities of about 270 m s -1 , of fibre metal laminates (FMLs), which consist of relatively thin, alternately stacked, layers of an aluminium alloy and a thermoset glass fibre epoxy composite, have been investigated. The effects of varying (a) the yield strength, tensile strength and ductility of the aluminium alloy layer, (b) the surface treatment used for the aluminium alloy layers and (c) the number of layers present in the FML have been studied. It was found that increasing the strength of the aluminium alloy increases the quasi-static flexural strength of the FML, providing that good adhesion is achieved between the metal and the composite layers. Further, increasing the number of alternating layers of the aluminium alloy and fibre composite also somewhat increases the quasi-static flexural properties of the FML. In contrast, increasing the strength of the aluminium alloy had relatively little effect on the impact perforation resistance of the FML, but increasing the number of alternating layers of aluminium alloy and fibre composite did significantly increase the impact perforation resistance of the FML. The degree of adhesion achieved between the layers had only a negligible influence on the impact perforation resistance.

“…The main problem with these products is their predominant brittleness so that they are strongly limited by their deformation processes. 22 In contrast to FMLs, metal/polymer/metal sandwiches exhibit a good formability for different sheet forming processes, 23 coming close to the values of the monometal used. They generally consist of alternating layers of metal and polymer, normally bonded by an adhesive layer.…”

“…19,20 Compared to the monomaterials used, Al and FRP-FML show an improved behavior. 21,22 They exhibit excellent fatigue and high-specific-static properties as well as an improved impact resistance, flame resistance and ease of manufacture and repair. 23,24 As described by Bourlegat et al, 25 these type of sandwiches can be divided into three groups following the different fiber adhesive layers used.…”

“…They generally consist of alternating layers of metal and polymer, normally bonded by an adhesive layer. More and more, they find their field of application in the automotive industry and are used for parts in automotive bodies such as roofs, bonnets, oil pans and floor parts due to their good formability and the possibility to combine properties of the single materials -such as high stiffness and strength, 22 high acoustic and damping capacity, vibration resistance and lightweight -in a hybrid system. 31 Using a polymer as sandwich core, some properties such as elasticity, high damping, high energy absorption and acoustic capacity can be designed in a wide range.…”

Multifunctionality and the demand for improving the properties of construction materials make it necessary to leave the approach of monomaterials and combine them to fabricate composite structures, such as combinations of metals with polymers. This article focuses on metal-polymer-metal sandwich sheets. Bonding is improved using adhesive layers. These sandwich sheets are designed for their mechanical and thermal properties, working capacity and so on. A short background of composites structures, to be used in the automotive and aerospace industry, is presented. Moreover, fabricating processes and forming methods for composites are briefly introduced. Finally, a study of 316L/polypropylene/316L sandwich sheets, manufactured in a roll-bonding process and heating press process, is introduced. Their mechanical behavior and formability by deep drawing are discussed. IntroductionAspects of environmental protection and recycling are becoming more and more important in our society and are the driving forces for development, especially in the area of aviation as well as automotive and transport. To fulfill the rising demands, ecological standards for new products can be a solution -for example, taking factors such as saving resources, sustainability and recycling as well as functionality, design and others into consideration. Novel materials with new and improved functions engender a high interest in the industrial community.Monomaterials of metals, ceramics or polymers cannot fulfill all the technological requirements for a variety of industrial applications. The activities in physics and chemistry as well as engineering are leading to materials with superior properties -often by combining monomaterials to hybrids. 1 Some industrially applied composite materials can be classified as follows: Sandwich composites are understood to be multilayered structures. By using these combinations, it is possible to 'tailor' the properties of special components by choosing the accurate combination of monomaterials, thus providing functionality to fulfill the qualified demands on modern materials and structures. 7 As defined by Zenkert, 8 they are a combination of materials with minimum one of higher strength to create a composite with selected lightweight properties. They are represented, principally, by fundamental patterns of two skin sheets, which are thin but of high strength and stiffness. These skins include a relatively thick, low-density core. These sandwich composites are widely used for engineering applications because of the extremely high stiffness-to-mass ratio.Sandwich materials can be formed with numerous skin (e.g. steel, aluminum alloy sheets etc.) and core materials (polymer foils or fiber-reinforced plastics (FRP), with polymer layers being homogenous or structured), and they are often bonded together using an adhesive agent. Because of being quite simple to manufacture using lamination, roll-bonding or heat-press joining processes as sketched in Figure 1, they exhibit a great potential for future use. 9,10 Moreove...

“…Este fato pode levar a deficiências na resistência (mecânica, térmica e de degradação) da estrutura em que o compósito foi aplicado. A absorção de umidade pode alterar a T g e este fato pode ser observado na curva da tan δ do DMA [45][46][47]. A técnica de DMA pode ser utilizada ainda para avaliar o comportamento desses compósitos e compará-los com materiais convencionais, além de verificar a influência dessas mudanças de condições ambientais nas suas propriedades [31].…”

ResumoMateriais compósitos poliméricos vem sendo estudados nas mais diversas áreas da ciência dos materiais com o objetivo de substituir outros tipos de matérias-primas e melhorar o desempenho na sua aplicação. Dentre as diversas técnicas existentes, a análise dinâmico-mecânica (DMA) tem-se mostrado uma boa alternativa para avaliar as propriedades destes compósitos, em especial os parâmetros viscoelásticos em função do tempo, temperatura ou frequência. Propriedades importantes como como módulos de armazenamento e perda, e temperaturas de transição podem ser obtidas através desta técnica. O presente artigo traz uma revisão a respeito da técnica de DMA, suas vantagens em relação a outras análises térmicas e mecânicas, o comportamento de materiais compósitos poliméricos durante a análise e os parâmetros que podem ser estudados por ela. A importância da análise no estudo de materiais de engenharia também é relatado, em especial em aplicações aeroespaciais.

Dynamic Mechanical Analysis (DMA) of Polymeric Composite Materials AbstractPolymeric composite materials have been studied in many fields in materials science, with the aim of replacing other materials and reaching better performance when applied. Among the existing techniques, a great alternative to evaluate composites properties is dynamic mechanical analysis (DMA), especially when viscoelastic parameters need to be studied as a function of time, temperature or frequency.Important properties, such as storage modulus, loss modulus and transitions temperaturescan be determined by this technique. The present paper brings a review about DMA, the advantages of this technique compared to others thermal and mechanical analysis, the behavior of polymeric composite materials during the tests and the properties which can be determined by DMA. The importance of DMA in the study of engineering materialsis also presented, especially when applied in aircraft structures.
