The Selection of Resin Material Based on the above four points, we must select molding materials firstly.
We select epoxy resin composites as molding materials for insulation space-components, separately loaded in A and B tanks.
Secondly, materials must be fully stirred before mixing.
Summary Molding materials and molding process directly affect the quality of insulation space-components.

Newly designed airframes are increasingly advantaged from the use of multiple material systems including carbon and glass fiber reinforced polymers and novel metallic materials for skins, fastening systems and structural components.
The reasons for this are that the performance improvements gained from multi-material integration are greater than the intrinsic characteristics of any single materials system.
Al-Li base materials are well positioned to contribute in new design methodologies [2].

Database Development Process On the basis of compiling nearly one thousand pieces of domestic and foreign legends, making basic research of home textiles design as the breakthrough, home textile design legends have been effectively deduced and cleared up by taking the combination of science and useful classification.
A good set of Chinese classical style bedding designs depends on outline, the harmonious integration of traditional patterns and materials.
Designers use flowers, stems, leaves, fruits of plants and other material to change in pattern.

Introduction High-speed processing is the cutting under the condition of high speed and low load, can cut the material at low speed with high load.
Fig. 1 Beverage bottles of the hollow mold cavity structure Fig. 2 The path and partial amplified image of cavity roughing machining Beverage bottles of the hollow mold cavity structure The hollow mold cavity of a bottle is shown in Figure 1, mold material for the plastic mold steel is 3Cr2NiMnMo, and hardness is HB340, cavity dimensions: length 197mm, width 78mm, the maximum depth of 55mm.
cavities roughing machining The main goal of roughing machining is to pursue the material removal rate per unit time, and prepare geometry contour for the semi-finished workpiece.

Apparently, the research of rubber crack propagation direction was not very sufficient, three-dimensional crack propagation of rubber material has not been reported so much.
G.J.Lake [6] etc. studied the fatigue fracture of the rubber material systematically; defined the absorbed energy of crack expanding per unit area as the energy release rate (tearing energy) G (Eq. 1)
Fig.1 Jmax Finite element model Bead rubber specimen crack growth direction Jmax Criteria validation Selected the wear-resistant layer rubber material (TVE) in bead, prepared specimens according to national standards (Fig. 2), preset 6mm initial crack in geometric center of the two rubber samples which direction relative to external force were 90° and 45° respectively.
