Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientific and Technical Information (STI) Program Office plays a key part in helping NASA maintain this important role. The NASA STI Program Office is operated by Langley Research Center, the lead center for NASA's scientific and technical information. The NASA STI Program Office provides ...

This paper outlines an experimental investigation carried out for the analysis of failure mechanisms in fibrous laminated composite plates containing stress raisers, in the form of cutouts, under static biaxial planar compressive loadiing. A specially designed biaxial loadiing frame was used to test a series of 48 ply graphite/epoxy composite laminated plates with centrally located circular hol...

The ability to mimic the structure of the natural extracellular matrix is a successful key for guided bone regeneration (GBR). For the regeneration of highly organized structures such as heart and bone, aligned fibrous membranes could provide anisotropic mechanical and biological properties which are adequate topographic guidance to cells. Here, novel nanofibrous membranes were developed throug...

The paper presents a numerical simulation of the contact interaction fibrous polymer composite materials in finite element ANSYS package and studies friction coefficients for cells with wear 0%, 25%, 50% 75%. To predict coefficient composites it was proposed to use method mechanics – local approximation. With help simulation, fields distribution normal stresses zone were obtained corresponding ...

Porous carbon/cobalt (C/Co) composite nanofibers with diameters of 200-300 nm were prepared by electrospinning and subsequent carbonization processes. Two polymer solutions of polyacrylonitrile (PAN), polyvinyl pyrrolidone (PVP), and Co (CH3COOH) 2 (Co (OAc) 2) were used as C/Co composite nanofiber precursors. The study revealed that C/Co composite nanofibers were successfully prepared and coba...

The triaxial test results of municipal solid waste (MSW) with different fibrous content show that reinforcement materials is the key factor affecting mechanical properties MSW. Thus, MSW regarded as a composite (plastic +textiles) and paste (i.e., any other non-fibrous materials). Under load, its behavior determined by two listed previously. This study introduces notion fibrous-reinforced param...

This study systematically investigates the role of graphene oxide (GO) and reduced GO (rGO)/silk-based composite micro/nano-fibrous scaffolds in regulating neuronal cell behavior vitro, given limited comparative studies on effects family materials nerve regeneration. Fibrous can mimic architecture native extracellular matrix are potential candidates for tissue engineering peripheral nerves. Sil...
