| titleOfInvention | Comprehensive zero expansion composite material laminate in plane |
| abstract | The utility model relates to zero expansion composite material laminates comprehensive in a kind of plane.The utility model is made of carbon fibre resin layer and aramid layers by curing molding.The carbon fibre resin layer and aramid layers are by certain thickness ratio interval laying.Carbon fibre resin layer machine direction is along 0 °/90 °/45 °/135 ° circulation layings.The warp direction of aramid layers is along 0 °/45 ° circulation layings.The overlay thickness and machine direction of carbon fibre resin layer and aramid layers are symmetrical about neutral surface.The utility model utilizes the mixing Lay up design of current material, and making its thermal expansion coefficient of all directions along face of laminate is 0, realizes comprehensive zero thermal expansion in the plane of material.It can be applied to space hyperfrequency remote sensing reflector, its type face precision made to meet electrical performance demands, i.e. reflecting surface thermal deformation RMS≤10 μm. |
