AbstractThe influence of flexible interlayers/interphases on the performance of unidirectional fiber reinforced composites is studied. Micromechanical analysis based on the embedded composite cylinders model is used to study the stiffness as well as the internal stress distributions within the matrix phase of composites. Based on the results of the analysis, a criterion is proposed for the selection of optimal interlayer thickness for fiber composites. The proposed criterion gives results which seem to correlate well with the experimental data published in the literature.

Sisal fiber reinforced composites are being replaced with manmade composites as these materials are difficult to manufacture and non biodegradable. On the other hand, the natural fiber reinforced composites such as sisal fiber reinforced composites shows less strength compared to manmade composites. The objective of the present work is to explore the mechanical properties of sisal fiber composites and hybrid sisal composites using analytical and experimental methods. The sisal composites and hybrid sisal composites are prepared by using hand layup techniques. The hybrid composites are prepared by reinforcing nano carbon powder and sisal fibers in a polymer matrix with the weight fraction of 9% of carbon powder and 50% of sisal fiber. The elastic modulus of polymer matrix with carbon powder reinforcement and polymer matrix, carbon powder and sisal fiber reinforced composites are identified by conducting suitable experiments. Later by using the finite element method, the fracture behavior of sisal fiber composites and hybrid composites are estimated. The energy released (ER) and energy required to create the surface (ES) are estimated to identify the critical crack length of the respective material. The present work is used for the design of sisal fiber composites with respect to young’s modulus and fracture response.

The objective of this study is to investigate the fatigue behavior of sisal fiber reinforced with carbon nanotubes. The hand lay-up technique is used to prepare the composite material samples. The fatigue response of pure polymer matrix, composite material which is prepared by reinforcing a sisal fiber reinforced with a polymer matrix was studied. The effectiveness of nano reinforcement of fatigue response is identified from experiments. Later, the fatigue response of sisal and nano particle reinforced sisal fiber composites (hybrid composite) is identified with irregularities by using finite element based software ANSYS. The elastic properties of sisal fiber reinforced composite and carbon nanotube reinforced composite is estimated by using the principles of Micromechanics and Macro-mechanics. The failure mechanism of polymer, conventional sisal fiber composites and nano filled sisal fiber reinforced composites are identified. The effect of the shape of the irregularities on the fatigue response is also identified from ANSYS software. From the present work, it is observed that, the reinforcement of nano reinforcement has considerable influence on the fatigue response of the resulting composite.

A hybrid composites mechanical properties consisting of un-treated and treated bast Kenaf fiber and E- glass fiber was investigated by varying the fiber glass weight ratio and using interplay fabrication method. A further comparison was made with corresponding properties of 100% wt E-glass fiber composites sample. The expected results were to have better composites performance in terms of toughness and impact strength as a comparison between the E- glass fiber reinforced composites and Kenaf fiber reinforced composites alone. All samples are prepared using typical samples preparation techniques. Result shows that the incorporation of E – glass fiber resulted in brittle failure and a higher amount of E-Glass fiber with low percentage of Kenaf fiber resulted in high strength, low ductile and low toughness behavior.

A study has been carried out to investigate the delamination and tensile properties of drilled composites made by reinforcing the natural fibers like hemp, jute, banana and vakka into a polyester resin matrix. The fibers extracted by retting and manual processes have been used to fabricate the composites. These composites are tested for delamination and tensile strength after drilling and compared with those of established composite like glass made under the same laboratory conditions. The Taguchi method with orthogonal array of L9 (34) was selected to realize the influence of the drilling parameters (cutting speed and feed rate) on delamination and tensile strength for various fiber reinforced composites. The results indicate that the delamination of the drilled natural fiber composites were in some cases better than those of glass fiber composites.

Purpose The purpose of this paper is to propose a comparative study between different structures composed of fiber-reinforced composite materials. Plates, cylinders and cylindrical and spherical shell panels in symmetric 0°/90°/0° and antisymmetric 0°/90°/0°/90° configurations are analyzed considering carbon fiber, glass fiber and linoleum fiber reinforcements. Design/methodology/approach A free vibration analysis is proposed for different materials, lamination sequences, vibration modes, half-wave numbers and thickness ratios. Such an analysis is conducted by means of an exact three-dimensional shell model which is valid for simply supported structures and cross-ply laminations. The employed model is based on a layer-wise approach and on three-dimensional shell equilibrium equations written in general orthogonal curvilinear coordinates. Findings The proposed study confirms the well-known superiority of the carbon fiber-reinforced composites. Linoleum fiber-reinforced composites prove to be comparable to glass fiber-reinforced composites in the case of free vibration analysis. Therefore, similar frequencies are obtained for all the geometries, thickness ratios, laminations sequences, vibration modes and a large spectrum of half-wave numbers. This partial conclusion needs further confirmations via static, buckling and fatigue analyses. Originality/value An exact three-dimensional shell model has been used to compare several geometries embedding carbon fiber composites and natural fiber composites.

Recent Developments

The longitudinal compression strength of single-directional fiber-reinforced composite is related to many factors, such as the mechanical properties, the fractions of components, and the distribution of flaws. There are no abroad and uniform opinions about its longitudinal compressing break mechanism yet. Thus, a review of recent developments in the compression strength mesomechanical forecasting models of single-directional fiber-reinforced composites is presented. The damage mechanisms based by these models and the affecting factors considered in them are analyzed. The application conditions of each models are shown, and the model choosing method of combining experiment and theoretical analyze is suggested.
