Hollow glass microspheres, as a lightweight reinforcing filler, are currently the most important application in the preparation of composite materials. Its uniqueness is as follows.
1)Hollow glass microspheres are hollow structures with low density and thermal conductivity, which not only greatly reduce the density of composite materials, but also give them excellent thermal and sound insulation properties. For example, the multi-layer insulation material developed by NASA's research center uses hollow glass microwaves as fillers, which not only provides better insulation but also improves the vacuum retention rate of the material system. Reduce maintenance costs and have good application prospects.
2) Hollow glass microspheres are spherical in shape and have the advantage of low porosity as ideal fillers (referring to the proportion of gaps between particles in the bulk volume of the particle material, which can be calculated based on the bulk density and microsphere particle density). The absorption rate of resin by particles is low, The impact on the viscosity and flowability of the polymer matrix is minimal. At the same time, it also makes the stress distribution of the final product reasonable, especially the surface stress distribution of the product is uniform, which improves the stiffness, hardness, and dimensional stability of the composite material.
3) Hollow glass microspheres have high strength. Hollow glass microspheres may appear as flowing powder to the naked eye, but they are essentially thin-walled sealed shells. The walls of the shell are mainly made of glass or ceramics, which have high strength and therefore have a certain reinforcing effect on composite materials.
