This current effort appraised the effect of fiber alignment on mechanical possessions of ramie fiber reinforced epoxy composites. In this study ramie fiber is used by means of reinforcement which treated with NaOH solution for improving the attachment strength among fiber and resin by eliminating moisture substances. Models of dissimilar alignments of ramie fiber reinforced composites remained made-up by hand – layup process and studied their mechanical possessions like tensile power and flexural power. The effort of this investigational study devises remained approved out to determine the mechanical properties. The results of this study indicate the orientation 0o /0o shows the enhanced mechanical properties compare to 0o /90o , 45o /-45o and 0o /45o /-45o /90o . It remained projected that the usage 0 o /0o orientation of ramie fiber composite as the alternates for artificial fiber in the development of the automobile body and engineering structure

Natural fiber composite is the most preferable research area in the modern situation due to its availability, applications, and ecofriendly quality. This paper deals with the influence of hemp fiber with the various compositions of the ramie fiber and some basic mechanical properties of banana fiber composites. The hemp fiber is maintained as 20 percentage of total volume. Then, the remaining volume percentage is shared with the ramie fiber and banana fiber with various combinations. Eleven specimens were prepared to identify the some basic mechanical properties. The chemical compositions were mentioned as a pie chart, and then experimental results were plotted as graphical representations like line diagram and radar diagram for clear identification that the composite with higher ramie fiber concentration provided the greater results in the mechanical behaviors. The suitable composite combinations were recommended based on their superior properties as conclusions.

With the “ecological consciousness” awakening of people, the natural fibers are very popular owing to their advantages such as environmental protection, low cost, easy to get and low density, and are used widely in the research and development about medical products. So, using natural fibers to make medical splint will also become a research hotspot. This paper introduces the research status of the medical splint and the characteristics of ramie fiber composite materials, and put forward the viewpoint of using ramie fiber composite materials to make medical splint and making it be intelligent. It has significance meaning for the further research of the intelligent splint for medicine on ramie fiber composite material.

AbstractSince the cytocompatibility of carbon nanofibers with respect to neural applications remains largely uninvestigated, the objective of the present in vitro study was to determine cytocompatibility properties of formulations containing carbon nanofibers. Carbon fiber substrates were prepared from four different types of carbon fibers, two with nanoscale diameters (nanophase, or less than or equal to 100 nm) and two with conventional diameters (or greater than 200 nm). Within these two categories, both a high and a low surface energy fiber were investigated and tested. Astrocytes (glial scar tissue-forming cells) and pheochromocytoma cells (PC-12; neuronal-like cells) were seeded separately onto the substrates. Results provided the first evidence that astrocytes preferentially adhered on the carbon fiber that had the largest diameter and the lowest surface energy. PC-12 cells exhibited the most neurites on the carbon fiber with nanodimensions and low surface energy. These results may indicate that PC-12 cells prefer nanoscale carbon fibers while astrocytes prefer conventional scale fibers. A composite was formed from poly-carbonate urethane and the 60 nm carbon fiber. Composite substrates were thus formed using different weight percentages of this fiber in the polymer matrix. Increased astrocyte adherence and PC-12 neurite density corresponded to decreasing amounts of the carbon nanofibers in the poly-carbonate urethane matrices. Controlling carbon fiber diameter may be an approach for increasing implant contact with neurons and decreasing scar tissue formation.

ABSTRACT This paper presents an evaluation study of the feasibility of harvesting energy from rolling tire deformation and using it to supply a tire monitoring device installed within the tire cavity. The developed technique is simulated by using a flexible piezoelectric fiber composite transducer (PFC) adhered onto the tire inner liner acting as the energy harvesting element for tire monitoring systems. The PFC element generates electric charge when strain is applied to it. Tire cyclic deformation, particularly at the contact patch surface due to rolling conditions, can be exploited to harvest energy. Finite element simulations, using Abaqus package, were employed to estimate the available strain energy within the tire structure in order to select the optimum location for the PFC element. Experimental tests were carried out by using an evaluation kit for the energy harvesting element installed within the tire cavity to examine the PFC performance under controlled speed and loading conditions.
