To increase understanding of damage evolution in advanced composite material systems, a series of large deflection bending-compression experiments and model predictions have been performed for a woven glass-epoxy composite material system. Theoretical developments employing both small and large deformation models and computational studies are performed. Results (a) show that the Euler–Bernoulli...

adhesive bonding technology is being used in a variety of modern industries, including the automotive, aerospace, maritime, construction, defense and so on. on the other side, polymeric nano - composites attracted both academic and industrial interests in the past decades. the scope of this paper is experimental investigation on the effects of the addition of alpha-alumina nanoparticles to the ...

Abstract The development of hybrid composite materials using honeycomb structure, typically a lightweight material, is commonly used in aircraft structures. However, the use with natural or synthetic remains unexplored literature. Therefore, this study aims to partially replace fiber, woven glass fiber kenaf and core. An experimental analysis investigated mechanical strength three different com...

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 ...

Unmanned Aerial Vehicles (UAVs) have high popularity, especially in the military field, but are now also being applied to private and public sectors. One of UAV components that require material technology is wing. The latest developed as a for unmanned aircraft wings composite has strength lightweight. This research aims identify materials can be used wing structures. method this qualitative wi...

Flow-induced fiber-bed compaction has considerable effects on through-thickness permeability due to resulting changes in fiber-volume-fractions. This study introduces a novel method for the simultaneous characterization of and unsaturated out-of-plane engineering textiles one single experiment. The measurement technique relies visually tracking flow-front positions during impregnation using cam...

Recent studies indicate that PEM fuel cell performance may be strongly influenced by in-plane permeability of the gas diffusion layer (GDL). The urrent study employs a radial flow technique for obtaining in-plane permeability of GDLs, using either gas or liquid as the impregnating fluid. A odel has been developed and experimentally verified to account for compressibility effects when permeabili...

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...
