In the composite materials manufacturing industry, the reinforced material, which is frequently used, is directed fibre that weaved, sewed or knitted out of fibre bundle.
As the distance between fibre bundles in this material is much more farther than the one of interstice inside fibre bundle, it can be regarded as dual-scale porous medium.
In the case studies, the precast volume’s material parameters: The macroscopic permeability is K=1×10-10m2, The porosity is Φ=0.5, The viscosity of the resin is μ=0.2Pa.s.

Guiding Strategy of Autonomous Learning under the Network Environment Lehui Huang1, a, Bin Gui2, b 1 Education School; Jiangxi Science & Technology Normal University, Nanchang, China 2 Education School; Jiangxi Science & Technology Normal University, Nanchang, China aHLH8899@163.com；b 154296945 Keywords: autonomous learning; network; guiding strategy Abstract：The network plays more and more important role in contemporary university students’ study and life.
First, according to the learning goals and plans, teachers can guide students to learn to identify materials needing to learn, and distinguish the learning materials from other interfering materials; then learn to determine the efficient and key information in learning materials, and remove redundant information; then learn to classify information; finally learn to process and use the information.
