High-damping and high-rigidity composites of Al2TiO5–MgTi2O5 ceramics and acrylic resin

Magnesium dititanate (MgTi2O5) with pseudobrookite structure: a review

“…Since MgTi 2 O 5 has relativity high thermal stability among pseudobrookite-type phases, Al 2 TiO 5 -MgTi 2 O 5 solid solution has been investigated [17][18][19][20][21][22]. Moreover, our group has studied porous MgTi 2 O 5 as a third-generation diesel particulate filter material with well-balanced properties, such as low thermal expansion, low cost, high-temperature stability and potentially good mechanical properties [23][24][25][26].…”

Mechanical Properties

“…Damping materials fall into four categories: (i) materials exhibiting high loss modulus but low loss tangent (such as cast iron, metal-matrix composites [6][7][8], shape-memory alloys [9][10][11][12] and acrylic impregnated ceramics [13]), (ii) materials exhibiting high loss tangent but low loss modulus (such as rubber and other polymers [14,15]), (iii) materials exhibiting low values of both loss tangent and loss modulus (such as quartz particle filled epoxy [16], short carbon fiber filled nylon [17], interpenetrating polymer networks [18], hot-compacted polyethylene/polypropylene [19] and short jute fiber filled polymer blend [20]), Graphite network cement-matrix composite [21] 9.26 0.811 7.502 2.47 Nanoscale Cu-Al-Ni shape-memory alloy [9] 22.06 0.196 4.43 0.93 Tungsten (95%) with In-Sn [9] 161 0.05 8.1 0.63 Acrylic impregnated ceramic [13] 60 0.04 2.4 0.31 Quartz particle filled epoxy [16] 3 0.15 0.45 0.26 Short carbon fiber filled nylon [17] 13 0.05 0.7 0.2 Hot-compacted polyethylene/polypropylene [19] 5.4 0.083 0.45 0.19 Interpenetrating polymer networks [18] 0.13 0.3 0.040 0.11 Short jute fiber filled polymer blend [20] 1 0.1 1 0.1…”
