[0024] The glass fiber reinforced plastic profile skeleton and glass fiber reinforced plastic door skin are used to make door panels with light weight and high strength. Compared with traditional door panels, the strength will be greatly improved and the corrosion resistance is strong. The glass fiber reinforced plastic door has good resistance to acids, alkalis, salts, most organic matter, seawater and moisture. The door panels are rust-proof and have higher corrosion resistance than conventional door panels. They can be used in rainy, humid and coastal areas and corrosive places. They have significant sound insulation and can be used in busy downtown areas. They have good fatigue resistance, and the cross-section of the fibers and the matrix in the glass fiber reinforced plastic can prevent the expansion of cracks caused by the stress on the material. It has a strong fatigue strength limit, ensuring the safety and reliability of the glass energy-saving door panels, and has good electrical properties. The glass fiber reinforced plastic door is a good insulating material that can withstand higher voltages without damage, is not affected by electromagnetic waves, does not reflect radio waves, and has good wave transmittance. Therefore, the glass fiber reinforced plastic door has special uses in buildings with communication systems, has good sealing, and the linear expansion coefficient of the glass fiber reinforced plastic door is lower than that of steel and aluminum alloy, and is comparable to the wall The expansion coefficient of the body is similar. When the temperature changes, the FRP door will not have a gap with the wall or door frame. It is suitable for windy, dusty and seriously polluted areas. It has good weather resistance. FRP is a thermosetting plastic. After the resin is cross-linked, a three-dimensional network molecular structure is formed, which becomes an insoluble body and will not melt when heated. The deformation temperature of FRP profiles is above 200°C. The high temperature resistance is better than the low temperature resistance. Therefore, FRP doors can be used for a long time in environments with large temperature changes. It has good shock absorption and high elastic modulus of FRP profiles, which can reduce early damage caused by early resonance. The resin and fiber interface in FRP has shock absorption ability, which makes the vibration damping of the material very high, which is beneficial to improve the service life of the door leaf and also provides guarantee for the application of FRP door leaves in harsh environments. It is heat-insulating and energy-saving. FRP has low thermal conductivity and is an excellent thermal insulation material. Therefore, FRP doors have significant thermal insulation effect, which is especially suitable for areas with large temperature differences, high temperature and high cold.
