Properties Of Composites

This paper provides an theoretical analysis of the properties of fibre reinforced composite materials under antiplane waves. A self-consistent scheme is adopted in calculating the effective material constants. A new averaging technique is developed to account for the effects of the waveform. The model is then used to evaluate the effective dynamic properties of composites with randomly distributed fibers. Typical examples are presented to show the effects of different pertinent parameters upon the effective wave speed and the attenuation.

Drilling of fiber reinforced composite materials presents a plethora of questions to the engineers and scientists. A number of research endeavors have been made in the recent years to fully characterize the drilling process of fiber reinforced composite materials. The efforts have been made in the direction of optimization of the operating variables and conditions for minimizing the drilling induced damages. This paper presented the delamination analysis of drilled holes in coir fiber-reinforced polyester composites. The results indicated that the delamination factor in coir fiber-reinforced composites is lower comparing with glass fiber reinforced composites.

Metals are known for high ductility and have, been used to design and fabricate structural components for many years. However, composite materials are taking over traditional materials owing to their significant mechanical properties. Fiber-reinforced composites exhibit lower ductility and failure strain, resulting in brittle failure, limiting their application where high ductility is desired. In this study, an effort has been made to design, fabricate, and test continuous fiber-reinforced composites with improved ductility. A comparative analysis was performed for optimizing the failure strain of different woven fiber-reinforced composite materials under both on-axis (0°/90°) and off-axis (±45°) loading. The materials include carbon/epoxy, E-glass/epoxy, and jute/epoxy composite. The tests were performed according to ASTM D3039 standard. The strength of all tested composites in on-axis and off-axis loading was obtained from tensile test results. But failure strain was limited in on-axis loading. Interestingly, glass/epoxy composite showed improved failure strain, by 90%, without much loss in tensile strength in off-axis loading than on-axis loading. The jute fiber revealed limited tensile strength and failure strain in both loading conditions.

Composite Bridges

Composite materials are often used in the construction industry nowadays. Including such industries as construction of bridges – unique structures. Today it is possible to produce from FRP not only separate bridge parts and single structural elements, but also entire span structures and one-piece composite bridges made as a monoblock element. The architecture of contemporary footbridges built with the use of fiber reinforced composite plastics in recent decades is being studied and analyzed in the article. The case-study examines the history of plastic composites as structural materials and the trends and evolution of the design of plastic products. The paper proposes a classification of modern pedestrian bridges made of fiber reinforced composites (based on a combination of innovation in the use of materials and in the design). The following three classes are distinguished: composite materials + traditional design; composite and traditional materials + hybrid design; composite materials + new design. The most recent examples of objects belonging to each of the three groups identified in the classification were reviewed and analyzed in course of the study (including contemporary Russian examples of composite pedestrian bridges). Particular attention is paid to the most advanced technologies, such as 3D-printing of composite bridges, as well as a number of other contemporary experimental production methods. The experience of scientists and manufacturers from Germany, Spain, Great Britain, China and other regions of the world has been studied. Further research and application of modern fiber-reinforced composites in combination with the latest production technologies of 3D-printing and computer parametric design can contribute to the development of modern bridge construction, which would be helpful for expanding the typology of structures and improving the design of new structures.
