Fabrication and characterization of eco‐friendly human‐hair derived porous carbon‐filled carbon fabric‐reinforced polymer composites

“…A comparison is shown between some important results obtained from the present study such as flexural strength, flexural modulus, storage modulus, electrical conductivity, and bulk density of CPCs with the some reported values in the open literature using different fillers like carbon black [15], glass particles [15], ceramic particles [15], natural graphite powder [20], graphite flake [22], and CNTs [26] as demonstrated in Table 2. It can be observed that HHCfilled CPCs exhibit comparable mechanical and dynamic mechanical properties and even in some cases it shows higher properties such as HHC-filled CPCs give better flexural strength than ceramic particles, nano-carbon, natural and exfoliated graphite and CNTs.…”

“…Despite of the excellent combination of properties the CPCs have poor thermal and electrical conductivity, poor high temperature stability, low specific mechanical strength, poor tribological characteristics, and very high cost. Hence, the researchers have incorporated various fillers such as glass, ceramic and carbon black micro particles [15], metal particles (zinc) [16], zinc oxide and silicon carbide [17], solid lubricant (graphite) [18], nano-carbon black [19], natural graphite powder [20], exfoliated graphite [21], graphite flake [22], carbon fiber powder [23], and carbon nanotubes (CNTs) [24][25][26] in composites either to improve some of the poor properties, and/or to decrease cost of the products and also to enlarge the scope of CPCs usage. Since most of the fillers used here are obtained from non-renewable resources such as petroleum oil and gases, inorganic materials, etc.…”

Seismic performance investigation of new lateral bracing system called “OGrid-H”

“…On the other hand, under a moderate earthquake, it is not economically justifiable to designing a structure which remains elastic [5][6][7]. So, in order to dissipate earthquake energy, the structure should experience inelastic behavior [8][9][10][11][12][13][14][15]. Extensive research has been performed to increase the ductility of concentric braces [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].…”
