Advantages and Disadvantages of Using Composite Laminates in The Industries

With today’s growing interest toward composite materials and their augmentation as part of integrated business from aerospace engineering, medical applications and others, which are getting increasing dependency on composite materials in recent operations. However, the most sophisticated composite materials still need to rely on the other integrated sub-sets of components. On the other hand, there certain limitation and flaws that exist within composite materials’ component that can cause and error to grow way beyond control and can impact its main master component. These sorts of limitation and flaws also would impact the engineering targets from perspective of resiliency built into the daily operations that is also pointed it out in current article.


Benefits and Drawbacks of Using Composites
Polyesters are the most widely used resin systems. Epoxies comes in second for their higher cost, with advantages of having higher adhesion and less shrinkage than polyesters. Using composites has their own pros and cons. Depending on their purposes, trade-offs should be considered when implementing composites in a design. (Table 1)summarizes the advantages and disadvantages of composites. ii. Resistant to fatigue and corrosion degradation.
ii. Matrix is susceptible to environmental degradation.
iii. High strength-to-weight ratio.
iii.Transverse properties may be weak.
iv. The fibre pattern can be tailored to efficiently sustain the applied loads. This directional tailoring capabilities allow products to meet the design requirements.
iv.Costs of raw materials and fabrication are expensive.
Composites have been incorporated in many fields. This    Fibre-reinforced composite materials own various functions in most industries, especially the aerospace industry, due to the high specific stiffness. Nonetheless, the expense of conventional composites is also noticeable. Ordinarily, Haphazard divided fibre reinforced composite materials appeared as affirming the most outstanding alternative materials for unique manufacturing challenges, joining the methods and the basic material selection considerations for multi-material lightweight structures due to the mass production capabilities and low cost [2]. For instance, the possible use in the automotive industry was recorded. In contemplation of expanding the application, meticulous material characterisation is needed. Subsequently, the major complication in the quite exploring models of the geometry at the micro-level of 35-40% fibre volume ratios, which is even more appeared at the highest aspect ratio among the different types of reinforcements [3].
Glass-fibre reinforced composite materials showed limited applications in terms of construction and building industry for several years. Recently, well potential for the applications of fibrereinforced composite materials for the numerous applications due to expeditiously retrofit and repair deteriorating infrastructure is being achieved [4]. Moreover, mechanical properties of fibrereinforced composite materials closely depend upon the properties of the component materials such as void content, type, orientation, fibre distribution and quantity. On the other hand, the main concept of the interfacial bonds and the mechanism of load transfer at inter laminar also play a vital role [5].Accordingly, varied researchers discuss about the design process of short fibres reinforced composite materials. Therefore, they are ready for using to aim attention at the strength properties of the composite materials that reported the effects of them on shapes of the fibres in shortfibres glass composite materials [6]. The flexural strength, vertical stress generated by bending moment of avoided short-fibres reinforced composites were studied by considering the effects of fibre orientation and length on mechanical properties. In addition, a short while ago, efforts to reduce the weight of automobiles by the increased use of plastics and their composites, have led to a growing penetration of short-fibre reinforced injection moulding thermoplastics into fatigue-sensitive applications [7]. Mainly, shortfibre-resin matrix composite materials are minor fatigue resistance than the correspondingly continuous fibre reinforced composites, which is extensively applied in the piping and pipeline systems and the pressure vessels for all major chemical industries [8].
