The density of this material is very low, mainly because a large number of hollow glass microbodies are dispersed evenly in the matrix material. The surface of these microspheres is optimized and processed by advanced chemical processing technology, which is further integrated with materials to further enhance the performance of the whole material. Hollow glass microsphere is a spherical hollow particle with a hard outer shell, which is gray or gray. Its main components are SiO2 and Al2O3, and the wall thickness is 8%, 10% of its diameter. The requirements for the matrix material are strong adhesion, low water absorption, high thermal performance and excellent electrical properties. The epoxy resin is the first choice. Because of its good bonding strength, thermal stability, dimensional stability and processing performance are more prominent. Diluents, curing agents and surface modifiers should also be added to the synthetic process of the materials. After the introduction of a large number of hollow glass microbodies with a diameter of 20 and 150 microns, the density of the whole material will be reduced to between 0.46 and 0.65. The material at this time is called a pure composite foam material.

In order to further reduce the proportion of materials, some larger hollow spheres are added, which are different from that of the microspheres.

Properties of typical composite foam materials

Properties of typical composite foam materials

The glass microspheres described above are a high strength fiber synthetic sphere. Their sizes are much larger, and the outer diameter is from 10mm to 110mm. The proportion of composite foam containing three components can reach 275 to 560kg/m3, and three components are called composite foam materials.

The density range of the pure composite foam from 380kg/m3 to 650kg/m3 can be applied to any depth of sea water.

The density range of synthetic composite foam from 275kg/m3 to 560kg/m3 is generally used in water.

In the next 4000 meters of the sea. Composite foam is most widely used in the working environment of deep water. Typical composite foam material properties such as diagrams.

The same material is different due to different application conditions. In order to achieve the best performance of the float material, we can design and select different types of float materials according to the different depth of float material and practical application. Generally, the application of these three materials in different depth of water is shown in the picture.

The development of deep water and deep oil exploration has led to the demand for the floating tube materials of the light high strength riser in the ocean. The composite material can be used in a global Quanhai deep, can meet the requirements of deepwater petroleum exploration [2].
