Recently, with the development of intelligent materials in civil engineering fields, a kind of novel piezoelectric composite using piezoelectric ceramic as functional material and cement as matrix was developed.
This kind of composite has many merits such as good piezoelectric properties, high electromechanical coupling properties, low mechanical quality factor and low acoustic impedance, thus it has great potential in solving the compatibility problem between traditional intelligent materials and concrete material[4-7].

Introduction The carbon fiber/resin composites are used in many industries including automotive, infrastruct- ure and aerospace, exhibiting superior strength to weight ratios than traditional materials [1].
To measure the Tg, we use the Dynamic Mechanical Thermal Analysis (DMTA) techniques, which can monitor changes in the storage and loss moduli and the loss factor of the material.

Though waste paper recycling will increase cost and difficulty due to cleaning sundries and ink, energy consumption and the amount of paper auxiliary materials such as aluminum sulfate, caustic soda, etc. which pollute environment can be reduced.
R-Tech Company produces E-cubes packaging material made of recycled waste paper.
This material can package fragile goods after adding fillers.
In Japan, waste paper has been the main paper raw material, accounting for 60% of all paper materials.
The reciprocating piston will compress the pulp into plug-shaped material.

Being resistant alloys, they show a reduced machinability, like other difficult-to-cut materials, such as nickel-base superalloys and titanium alloys.
