Crushing behavior of hybrid hexagonal/octagonal cellular composite system: All made of carbon fiber reinforced epoxy
( Elsevier, Ltd , 2014 , Article)Cellular carbon fiber-reinforced plastic (CFRP) composites, either unfilled or filled with foam, may be of interest for energy absorption application due to their improved crashworthiness. In the current paper, new ... -
Crushing behavior of hybrid hexagonal/octagonal cellular composite system: Aramid/carbon hybrid composite
( Elsevier, Ltd , 2014 , Article)In the current paper a series of experiments were conducted to assess the crashworthiness of cellular hexagonal/octagonal composite device. Each device composed of 6 cells of carbon fiber reinforced composite (CFRP). ... -
The effect of fiber orientation on the energy absorption capability of axially crushed composite tubes
( Elsevier, Ltd , 2014 , Technical Report)An experimental investigation to optimize the absorbed energy of axially crushed composite collapsible tubular energy absorber devices was carried out. Different fiber orientation were used in this study (0/90, 15/−75, ... -
Effect of water absorption on the mechanical properties of long date palm leaf fiber reinforced epoxy composites
( American Scientific Publishers , 2015 , Article)This paper examines the effect of the first 24 hours water absorption on the mechanical properties and morphology of the long date palm leave fiber (DPLF) and unidirectional reinforced epoxy composites. The mechanical ... -
Energy absorption capability of composite hexagonal ring systems
( Elsevier, Ltd , 2012 , Article)An extensive experimental investigation of inplane crushing of composite hexagonal ring system between platens has been carried out. Woven roving glass/epoxy hexagonal ring system with different angles and arrangement were ... -
An experimental investigation into mechanical behavior of hybrid and nonhybrid composite semi-elliptical springs
( Elsevier, Ltd , 2013 , Article)This study introduces a new composite semi-elliptical suspension spring by utilizing fiber reinforced composite strength in principal direction instead of shear direction. Three types of composites were tested, namely, ... -
An investigation into hybrid carbon/glass fiber reinforced epoxy composite automotive drive shaft
( Elsevier , 2011 , Article)This paper examines the effect of fiber orientation angles and stacking sequence on the torsional stiffness, natural frequency, buckling strength, fatigue life and failure modes of composite tubes. Finite element analysis ... -
Mechanical and thermal stresses in a functionally graded rotating disk with variable thickness due to radially symmetry loads
( Elsevier Ltd , 2008 , Article)Rotating disks have many applications in the aerospace industry such as gas turbines and gears. These disks normally work under thermo mechanical loads. Minimizing the weight of such components can help reduce the overall ... -
Stress analysis in functionally graded rotating disks with non-uniform thickness and variable angular velocity
( Elsevier , 2016 , Article)Stress field in functionally graded (FG) rotating disks with non-uniform thickness and variable angular velocity is studied numerically. The elastic modulus and mass density of the disks are assumed to be varying along the ...
