the value of the permeability in fluid flow through porous media is important for process investigation. in low reynolds number, the classic darcy’s law is suitable for simulation of fluid flow. in this paper, an experimental study for evaluation of preformed fiber permeability has been done. also, the deviations from the classical darcy law by experimental and numerical simulation of the navie...
الیاف شیشه، الیاف ظریف خمش پذیری از خانواده شیشه با اجزاء اصلی sio2-al2o3-cao-mgo و ناخالصی های قلیایی، اکسید های معدنی tio2,fe2o3 و افزودنی b2o3 و فلئور می باشد و در حالت مذاب بصورت رشته های نخی شکل، رشته رشته می شود.الیاف شیشه به دو گروه اصلی پشم شیشه و الیاف پیوسته تقسیم بندی می شود و الیاف شیشه نیز بر حسب شرایط مصرف به چندین نوع e-glass , a-glass, c-glass , r-glass , s-glass , ecr-glas...
A Portland cement plaster wall system has many positive features, but one of the physical properties that it does not possess is flexural strength. It is because of the inability of the Portland cement plaster membrane to bend or flex that glass fiber strands were used in Portland cementbased plaster. There are various types of synthetic fibers on the market that will provide flexural strength ...
CHARACTERIZATION OF SHORT E-GLASS FIBER REINFORCEDGRAPHITE AND BRONZE FILLED EPOXY MATRIX COMPOSITES
The mechanical characterization of short E- glass fiber reinforced, graphite and sintered bronze filled epoxy composite was carried out in this study. The aim of the present study was to develop tribological engineering material. In this study the flexural strength, theoretical and experimental density, Hardness and Impact strength of composites was investigated experimentally. The results show...
This work reports the high-velocity impact response of multiscale anisogrid composite (AGC) panels. The aim of the present study is to evaluate the influence of surface-modified multi-walled carbon nanotubes (S-MWCNTs) at different S-MWCNTs contents (0-0.5 wt.% at an interval of 0.1 wt.%) on the high-velocity impact responses of E-glass/epoxy AGC. Surface modification of MWCNTs is confirmed by ...
during the last decades a new class of materials named fiber/metal laminates (fmls) was introduced. it is a hybrid composite consisting of alternating thin layers of metal sheets and fiber-reinforced composite material. fmls have both low weight and good mechanical properties. in this study, the impact behavior of this attractive material is investigated. the effect of fiber angle, stacking seq...
BACKGROUND The radiopacity degree of posts is not enough for adequate visualization during radiographic analyses. Glass fiber post with stainless steel reinforcement has been fabricated in an attempt to overcome this limitation. AIM This study was designed to determine the influence of this metal reinforcement on the post mechanical properties. MATERIALS AND METHODS This study evaluated fle...

A Comparative Study on Quasi-Static Axial Crushing. Front. Mater. 4:42. doi: 10.3389/fmats.2017.00042 can Plant-Based natural Flax replace Basalt and e-glass for Fiber-reinforced Polymer Tubular energy absorbers? a comparative study on Quasi-s...
the creep behavior of basalt fiber reinforced epoxy (bfre) and glass fiber reinforced epoxy (gfre) composites was studied through tensile testing at high temperature. to study the effect of reinforcing epoxy, the micro glass powder (mgp) was added at various volume percentage into the epoxy resin in bfre composites. the initial strain for all the specimens were evaluated and compared with each ...
background: glass and quartz fiber posts are used in restoration of structurally compromised roots. accessory fiber posts are recently introduced to enhance the fiber post adaptation. this study evaluated the effectiveness of glass versus quartz accessory fiber posts. materials and methods: in this experimental study, 40 mandibular premolar roots with similar dimension (radius of 3.5 ± 0.2 mm a...
