Fibre Reinforced Composites

Fibre reinforced polymeric composites used in pressure retaining structures are seen as an attractive alternative to products made from conventional materials due to their corrosion resistance and high strength-to-weight ratio. The reluctance in adopting composite materials, however, is due to a limited understanding of the material behaviour under a variety of loading and environmental conditions, and lack of qualified design methodologies. It is the purpose of this paper to address fundamental and applied issues regarding their feasibility and current limitations in pipeline applications. A review of pertinent research results with respect to the local and global behaviour in composite pipes will be discussed.

Electroless Ni

Magnesium alloys are being used as structural components in industry because of their high strength to weight ratio. But their high electrochemical activity and poor corrosion resistance limited their applications. Therefore, surface modifications are needed for protection purpose. This paper studied the anodic micro-arc oxidation and electroless Ni-P plating surface modifications on AZ80 magnesium alloy. The SEM, XRD and EDS were used to characterize the surface coating. It shows that a micro-porous MgO layer with the pores size 5 – 20 μm was fabricated on the bare magnesium alloy. The nodule Ni-P deposition could be prepared on the out layer of MgO with Ni/P atomic ratio being 1.4. The pores in MgO layer could be sealed by the following Ni-P deposition. Therefore the corrosion resistance of the magnesium alloy could be further improved.

Abstract The use of lighter materials is one of the efficient means to mitigate the increasing demands on fuel resources, reduce CO2 emissions. Mg is one of the lightest material available and possesses exciting range of properties such as low density and high strength to weight ratio. Despite such exciting properties, the applications of Mg and its alloys were very limited in aerospace, automotive and biomedical industries but recently the application is picking-up. The restricted application is attributed to anisotropy, poor corrosive resistance and inflammability of Mg. The current review addresses the barriers limiting the widespread application of Mg based materials. Furthermore, the mitigation of the problems of anisotropy, poor corrosion resistance, ductility and inflammability of Mg are critically reviewed. The findings of this research provide insights of the processing techniques, properties and how to address the potential barriers of limited applications. The review paper will assist and motivate the researchers to ponder and overcome numerous problems related to Mg and its alloys by understanding the importance of each problem discussed in this review. An attempt has also been made to arrange research status on issues and the mitigation thereof with respect to Mg and its alloys as single reference point.

Fibre Reinforced Composites

The conventional homogeneous materials can no longer effectively satisfy the growing demands on product capabilities and performance, due to the advancement in products design and materials engineering. Therefore, the fibre reinforced composites with better properties and desirable applications emerged. Natural fibres have high strength to low weight ratios and have good sound and thermal insulation properties. Combination of organic filler and inorganic matrix creates high-quality products such as fibre boards and composites. The great importance is attached to industrial hemp as source of the rapidly renewable fibres and as non-waste material. Industrial hemp fibre has great potential in composite materials reinforcement. However, improving interfacial bonding between fibres and matrix is an important factor for its using in composites. This paper deals with hemp fibre reinforced composites in civil engineering as component part of sustainable construction. Prepared lightweight composites based on original and pre-treated hemp hurds are characterized by selected physical and mechanical properties (density, thermal conductivity, water absorbability, compressive and tensile strength) in dependence on used inorganic binder (traditional Portland cement and alternative MgO-cement).

In this paper the various failure modes which occur in long fibre composites are described and discussed. The significance of each of these fracture mechanisms, in terms of their energy-dissipating capacity as well as their effect on the residual load-bearing properties, is considered. A brief review of both the destructive and non-destructive techniques used for detecting and characterizing defects and damage is presented. The ability of each technique to identify the various fracture mechanisms involved in the failure of long fibre reinforced composites is discussed and their overall suitability for damage detection evaluated.

The need for metallic biomaterials will always remain high with their growing demand in joint replacement in the aging population. This creates need for the market and researchers to focus on the development and advancement of the biometals. Desirable characteristics such as excellent biocompatibility, high strength, comparable elastic modulus with bones, good corrosion resistance, and high wear resistance are the significant issues to address for medical implants, particularly load-bearing orthopedic implants. The widespread use of titanium alloys in biomedical implants create a big demand to identify and assess the behavior and performance of these alloys when used in the human body. Being the most commonly used metal alloy in the fabrication of medical implants, mainly because of its good biocompatibility and corrosion resistance together with its high strength to weight ratio, the tribological behavior of these alloys have always been an important subject for study. Titanium alloys with improved wear resistance will of course enhance the longevity of implants in the body. In this paper, tribological performance of titanium alloys (medical grades) is reviewed. Various methods of surface modifications employed for titanium alloys are also discussed in the context of wear behavior.
