Hence, the effect of temperature and strain rate on the mechanical response of such thermoplastic composites are important when designing pipes using these materials [1, 2].
Materials and Method The tested injection mold composite was a 30 wt% of glass fiber/Polyamide 66 (PA6).
The material is suitable for injection molding and heat stabilized with improved hydrolysis resistance.

Then calcinate each type of the gel at 600°C for 2h to prepare photocatalytic materials with different doping amount of ZnO.
Calcinate equal amount of the dried gel powder of ZnO-TiO2 (5%) under 600°C for 0.5, 1, 1.5, 2, 2.5 and 3h respectively so as to produce different series of ZnO-TiO2 composite light catalytic materials.
