Source：China Composites Expo
Exhibitor: Tiance Technology Co., Ltd.
As a novel catalyst for resin, Al-POSS has unique cage structure and good dispersability. The fluidity and thermal stability of the resins can be improved. The curing temperature and curing time can be reduced, as well as the manufacturing costs.
Al-POSS is synthesized by combining metallic ion and cage structure through covalent bonds. Compared with other kinds of cyanate ester catalyst in the market, Al-POSS has an advantage of better dispersion. By using Al-POSS as catalyst, the flame retardation and toughness can also be improved.
The properties of Al-POSS are as follows:
1) White powder, nontoxic and no flavor.
2) Good dispersion in resin matrix.
3) Metallic ion content ~4-5wt%. The curing reactions of the cyanate estercould be effectively accelerated and curing temperature could be reduced by 40℃.
4) Improved mechanical properties of resins.
5) Good flame retardation of resins.
6) Good stability. Quality guarantee period is about 90 days at ambienttemperature, and ~180 days at low temperature.
The production has been provided to Beijing Satellite Manufacturing Factory and many other scientific research institutions, and received good feedbacks.

3. Product Name: SYM30 Medium-Modulus Carbon Fiber
Exhibitor: Zhongfu Shenying Carbon Fiber Co., Ltd.
The product is suitable for parts and components with high requirement for structural rigidity, for example, racing bicycles, fishing rods, and other products from sports, leisure, and other civilian industrial areas.
The most innovative point of SYM30 medium-modulus carbon fiber is the using of large tow precursor produced by dry-jet wet spinning method, which contributes to approximately 30% lower cost of production than that of carbon fibers with modulus on the same level. SYM30 possesses high modulus, outstanding tensile strength, high elongation and good processability, thus competitive price-performance ratio.
Authorized testing results are: Tensile strength ~5200MPa, Tensile modulus ~295GPa, Fracture elongation ~ 1.7%, Linear density ~ 740g/km.
SYM30 medium modulus carbon fiber has been brought to market for a period, and have been widely used in racing bicycles, fishing rods and other areas. The properties and performances of both fibers and composites meet the requirements for terminal products, and get widely recognized by customers.
