Performance testing of a carbon fiber array cathode in a hard-tube MILO

Preparation and performance testing methods of short carbon fiber reinforced wood(SCFRW) were briefly introduced and utilized. Mechanical properties and electric conductivity of SCFRW veneering sample boards were analyzed with carbon fiber and woodiness fiber in different quality ratios, moreover, conductivity models were put forward according to the temperature influence on surface resistivity of composites. The experimental results showed that the performance of woodiness fiber boards were effectively improved by joining of carbon fiber, especially the modulus of elasticity. Meanwhile, it also endowed composites good electric conductivity, and nonlinear least squares fitting models was intuitively suitable for the negative effect relationship between surface resistivity and temperature, which provided basis and guidance for preparation and processes optimization of conductive woodiness functional composites.

This study aimed to develop an extrusion and pultrusion system for producing carbon fiber-filled thermoplastic pellets. The extruder delivers a plastic melt to an impregnation die in sufficient volume and is pulled out along with the fibers. The fibers pass in a sideways stretched condition through spreader pins attached in the melt pool, which can then be wetted optimally. The wetting effect was also improved by immersing fiber in a coupling agent solution at an elevated temperature before feeding to the extruder die. For machine performance testing, polypropylene was used as a matrix resin with the following parameters: a screw speed of 5 rpm, a die temperature of 210 °C, and a pulling speed of 56 mm/s. The pull-out test was conducted to assess the interfacial shear strength (IFSS) between fibers and matrix. Scanning electron microscopy (SEM) was applied to characterize the quality of fiber impregnation. SEM characterized a good bonding performance between carbon fiber and the matrix. The average IFSS of the results indicated a good resistance of fiber–matrix bonding against a pulling force. It proved that the combination of the extrusion–pultrusion system can produce high-quality filaments as a raw material of composite pellets.

3D Orthogonal Woven

In this paper, the influence of damage and deformation on the electrical property of carbon fibers in the hat-shaped 3D orthogonal woven fabric-reinforced composite structure is studied. A method of producing parallel sensor arrays was proposed, in which the warp yarns made of carbon fibers were separated by isolated Kevlar fibers as weft yarns and Z-yarns. The sensor array unitized the self-sensing property of carbon fiber and could detect the damage and deformation distribution along the transverse direction of the composite under bending tests. Both the experiments and simulations had been conducted to analyze the mechanical and electrical responses of the carbon fiber array. By comparing the experimental results and simulation data, the method was validated and the influences of damage and deformation distribution on the resistance variation of carbon fibers were revealed.

According to the design method of composite material mechanics based on laminate theory, structure of an underwater vehicle, which is made of twill woven carbon fiber composite material, was analyzed simulatively under the lifting condition with the finite element analysis software. Performance parameters of the laminated composite material were obtained from the mechanical performance testing experiment and applied to the analysis. In the two point handling condition, for the underwater vehicle structure, maximum deformation or displacement has a large safety redundancy to the test standard value. And the structure maximum stress is far less than the allowable strength limit of carbon fiber laminated plate acquired from the tensile experiment. It has an obvious advantage compared with metal frame structures.

AbstractMost preparations for making neural recordings degrade over time and eventually fail due to insertion trauma and reactive tissue response. The magnitudes of these responses are thought to be related to the electrode size (specifically, the cross-sectional area) and the relative stiffness of the electrode material. Carbon fiber ultramicroelectrodes have a much smaller cross-section than traditional electrodes and thus may enable improved longevity of neural recordings in the central and peripheral nervous systems. Only two carbon fiber array designs have been described previously, each with limited channel densities due to limitations of the fabrication processes or interconnect strategies. Here, we describe a method for assembling carbon fiber electrodes on a flexible polyimide substrate that will facilitate the construction of high-density recording and stimulating arrays for acute use in peripheral nerves. Fibers were aligned using an alignment tool that was 3D-printed with sub-micron resolution using direct laser writing. Indium deposition on the carbon fibers provided a robust and reliable method of electrical connection to the polyimide traces. Spontaneous action potentials and stimulation-evoked compound responses with SNR > 10 and > 120, respectively, were recorded from a small (125 μm) peripheral nerve. We also improved the typically poor charge injection capacity of small diameter carbon fibers can be improved by electrodepositing 100 nm thick iridium oxide films, making the carbon fiber arrays suitable for electrical stimulation as well as recording.
