Cyclic Butylene Terephthalate (CBT)/carbon black (CB)/aluminum composites were prepared by melting blend method and their conductivity and mechanical property were studied by Milliohmmeter and material testing machine. The results showed that at below 1.6 wt% of flake aluminum（Al）, volume electrical resistivity and flexural strength of composites increased with Al content increases and reached the maximum value at 1.6 wt% of Al. Composites containing 18.4 wt% of CB and 1.6 wt% of aluminum exhibited excellent comprehensive performance (electrical resistivity, 20.3 Ω.cm; flexural strength, 40.0 MPa).

The Poly(vinylidene fluoride)(PVDF)/Cyclic Butylene Terephthalate (CBT)/carbon black (CB)/graphite (GR) composites were prepared by melting blend method and were studied by milliohmmeter and material testing machine. The results showed that due to the formation of CB and GR conductive network, the volume electrical resistivity of PVDF/CBT/CB/GR composites linearly decreased as graphite content increased at below 4 wt% of graphite, but it in turn increased when graphite content was higher than 4 wt%. Flexural strength showed an increase at below 1.6 wt% of GR and gradually decreased as GR content increased further. Differently, flexural modulus of composites declined as GR content increased. In all composites, the flexural strength was more than 25 MPa, which satisfied with the requirements of bipolar plates.

Calcium Sulfate Whisker

The effect of calcium sulfate whisker (CaSO4) on mechanical property, melting, crystallization and rheological properties of polyamide 1012 (PA1012) was studied by differential scanning calorimeter (DSC), rheometer and material testing machine. It was shown that CaSO4had no influence on melting temperate of PA1012, but can effectively enhanced nucleation ability of PA1012, which indicated that CaSO4was good nucleation agent for PA1012. The viscosity and storage modulus of PA1012 firstly increased and then decreased as CaSO4content increased. The results showed that CaSO4had little effect on tensile strength, but impact largely flexural strength.

In order to solve some problem of stress sensor in dynamic weigh rail, a new kind of inductive stress sensor based on magnetostriction effect of amorphous alloy was developed. First, the principle of sensor, and inferred its output equation were discussed. Second, the static characteristic experiment and the actual experiment on the material testing machine and the mine haulage rail were separately made. The results of the test have showed that this stress sensor has some characteristics as high measurement sensitiveness and accuracy. Also being simple, convenient and solid to install and use, so it is feasible to apply the sensor for the dynamic weigh rail.

We investigate the mechanical properties of Poly Vinyl Chloride (PVC)/ acrylnitrile-butadiene-styrene copolymer (ABS) composite material with an impact testing machine，a material testing machine and other accessory devices. The result shows that the mechanical properties of PVC/ABS composite are a function of composition, the addition of ABS improved the mechanical properties of PVC/ ABS composite，the impact strength and elongation at break rise significantly with increasing ABS content in PVC/ABS composite and appears maximum value，While the tensile strength and modulus almost decrease monotonously with increasing ABS content in PVC/ABS composite.

A new correction instrument of pectus excavatum is introduced which is designed for a minimally invasive technique (Nuss procedure). The instrument was made of pure titanium plates, and finished by machining, surface treatment and so on. The instrument was made up of correcting bar and fixing bar. The mechanical properties of the instrument was measured with electron universal material testing machine, the safety and validity was verified by clinical doctors after being implanted into the patient. Results showed that the mechanical properties of the instrument keep constantly after implantation for two years. It is lighter than the like product, and can lighten the patent’s and the doctor’s operation bearing. It had been applied in national hospitals, and results showed that it was of better biocompatibility, and few complications were found. Clinical treatment effects were satisfactory.
