Lamination Process

The development of hull material with ideal properties to meet all the operation requirements has posed the greatest challenge to flying the airship at high altitude for extended periods. Materials developed in our previous study with a laminated structure achieved high strength-to-weight ratio and excellent gas barrier property at a relatively low total weight. To optimize this novel design and obtain a more comprehensive understanding of the laminate properties, a parametric study involving lamination process parameters (temperature and time), and laminate structural parameter (reinforcement fabric construction), was conducted. The effects of lamination parameters on tensile, peel, tear and helium permeability tests were carried out to assess the laminates. It was found that the tensile strength of the laminate is predominantly determined by the fabric reinforcement material properties. The peel and tear strength results showed that increasing the lamination temperature from 185 °C to 200 °C improved respective strength values. Additionally, the analysis of failure modes and tear propagation suggested that laminate samples with progressive failure have better tear resistant property over those with brutal failure. Extremely low helium permeability was achieved, yet the gas barrier property was not affected by the lamination process parameters and fabric type.

C2C e-commerce rapidly develops, which is an important economic pillar. With the deepening of the network life, more and more people join the C2C e-commerce transactions. However, the credit problem of C2C e-commerce has serious hidden security problems. So, the paper analyzes the present situation of C2C e-commerce credit problem and points out the existing problems. Scientifically, systematically, validity, feasibility and comparability are taken as principles to establish the first level indicators that including commodity property, business services, and logistics services and to establish the secondary indicators that reasonable price, timely delivery and so on. Using AHP, the weight of each level indicator can be calculated. C2C e-commerce evaluation model is established. Then the model is improved on transaction amount and evaluation time, so it can provide a theoretical basis for C2C e-commerce credit evaluation system.
