Composites are composed primarily of reinforcement and matrix materials.
Reinforcement materials are divided into two classes of glass fibers and carbon fibers, and the matrix materials are primarily thermoplastic and thermosetting resins.
Composite materials are widely used in this area.

Lead strontium zirconate titanate (PSZT) ceramic is as one kind of piezoelectric materials can convert between stress and electric.
Introduction Lead strontium zirconate titanate (PSZT) ceramic as one kind of piezoelectric materials is with excellent piezoelectric properties.
However, elements Mn and Ce are with different effects on the grains growth of the PSZT materials.
By doping element Mn, grains of the PSZT materials will grow and porosity of bulk material will decrease.
