Ultrahigh Molecular Weight

Low-density polyethylene single-polymer composites (SPCs) reinforced with sandwiched ultrahigh-molecular-weight polyethylene woven fabric were prepared by insert injection molding. The process combines aesthetic and processing advantages. A processing temperature window (135–155°C) of a very short cycle time (less than 30 s) could be realized. The mechanical properties and morphologies of the samples were evaluated. The results suggested that the polyethylene SPCs were prepared successfully with concurrent increases in flexural strength (∼57%), tensile strength (∼164%), and impact strength (∼69%). The effects of different processing parameters including the nozzle temperature, injection pressure, injection speed, and the holding time were discussed. Numerical simulation results were used in the analysis.

M-AlN (surface modified aluminum nitride powder) suspensions for aqueous gelcasting were prepared Using NH4PAA as dispersant. The effects of pH value, NH4PAA amount and solid content on the rheological behavior of M-AlN suspensions were investigated. The results showed that low viscosity M-AlN aqueous suspensions with high solid content up to 55vol.% were obtained under the condition that the amount of NH4PAA was 0.9 wt. % of M-AlN powder, and pH value was about at 6.8. In spite of this, these suspensions still show a viscosity lower than 0.12 Pa•s at 100s-1, suggesting a good fluidity which can satisfy the requirement of gelcasting.
