Abstract

The invention relates to a light composite material, and in particular relates to a hollow microspheres and fiber body composite material. The light composite material consists of a base material, the fiber body and hollow microspheres which are uniformly distributed. The proportion of the total volume of the fiber body and hollow microspheres and the base material is (1:5)-(1:1). The base material is thermoplastic or thermosetting resin. The fiber body is at least one of fibrilia, carbon fiber, glass fiber, polypropylene fiber, aramid fiber and basalt fiber. The hollow microspheres are at least one of hollow glass microspheres and hollow ceramic microspheres. The volume ratio of the fiber body and the hollow microspheres is (1:5)-(1:1). The fiber body and the hollow microspheres are bonded together through the base material. According to the light composite material provided by the invention, the problem that current composite material is unsatisfactory in heat insulation, sound insulation, shock absorption and the like because the inner structure is almost a solid structure can be solved.

Description

technical field [0001] The invention relates to a lightweight composite material, more specifically to a hollow microsphere and fiber body composite material. Background technique [0002] Composite materials have been widely used in aviation, construction, automobile and other fields. The density of composite materials is generally relatively high. Although the density of resin-based composite materials is relatively low, it generally exceeds 1.5g / cm 3 . Most of the existing composite materials are solid structures inside, which are not ideal in terms of heat insulation, sound insulation, and shock absorption. As a new type of material developed by leaps and bounds in recent years, fiber composite materials have been widely used in engineering due to their special physical properties and stable chemical properties, especially their excellent light weight and high strength. [0003] In recent years, research reports on the modification of plastics filled with hollow glass...
