Embodiment 1

[0032] Such as figure 1 As shown, a lightweight fiber-reinforced thermoplastic composite sheet includes an outer layer 1, an intermediate layer 2, an inner layer 3, and a bottom layer 4 arranged in sequence; the outer layer 1, the middle layer 2, the inner layer 3, and the bottom layer 4 are heated and pressed The outer layer 1 is a flame-retardant decorative film layer; the middle layer 2 is a first fiber-reinforced thermoplastic flame-retardant resin layer; the inner layer 3 is a light-weight hollow glass microsphere filled flame-retardant resin layer; the bottom layer 4 is The second fiber-reinforced thermoplastic flame-retardant resin layer; the outer layer 1, the middle layer 2, the inner layer 3 and the bottom layer 4 can also be closely bonded to each other through a cold pressing process.

[0033]The flame-retardant decorative film layer is a polymer film material added with a flame retardant and has a decorative texture or pattern. The flame retardant decorative film...

Embodiment 2

[0049] A lightweight fiber-reinforced thermoplastic composite board, comprising a flame-retardant PVC composite decorative film layer, a carbon fiber-reinforced flame-retardant polycarbonate layer, a hollow glass microsphere-filled polycarbonate layer, and a carbon fiber-reinforced flame-retardant polycarbonate layer.

[0050] The flame-retardant PVC composite decorative film used in this example is a commercial product. The main base material is a PVC film with printed patterns. The surface is covered with PVF film to increase weather resistance and chemical resistance. The back has a pressure-sensitive adhesive layer. . The flame-retardant polycarbonate raw material is a commercial product purchased from Bayer AG in Germany. The material is compounded with polytetrafluoroethylene anti-dripping agent by adding sulfonate-based flame retardant and silicone-based flame retardant, which has excellent flame-retardant effect. The carbon fibers used are 30mm chopped fibers, which a...

Abstract

The invention relates to a lightweight fiber reinforced thermoplastic composite board. The composite board comprises an outer layer, a middle layer, an inner layer and a bottom layer which are sequentially arranged; the outer layer, the middle layer, the inner layer and the bottom layer are compounded to form a plate through heating and pressurization; the outer layer is a flame-retardant decorative coating; the middle layer is a first fiber-reinforced thermoplastic flame-retardant resin layer; the inner layer is a lightweight hollow glass microsphere filled flame-retardant resin layer; and the bottom layer is a second fiber reinforced thermoplastic flame-retardant resin layer. According to the lightweight fiber reinforced thermoplastic composite board. The composite board, the fiber reinforced thermoplastic flame-retardant resin layer is prepared by utilizing multiple layers of flame-retardant resin films and reinforced fibers which are uniformly dispersed among the layers through a hot-pressing method, the fiber reinforced thermoplastic layer has high tensile strength and tensile modulus, and therefore the overall structural rigidity and the puncture resistance of a sandwich structure are ensured; and meanwhile, hollow glass microspheres are used for filling, and therefore the specific density of a thermoplastic composite is further decreased.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a lightweight fiber-reinforced thermoplastic composite plate and a preparation method thereof. Background technique [0002] In the application fields of civil aviation, rail transit and special vehicles, there are often high requirements on the properties of materials, including mechanical properties, flame retardancy, weather resistance, chemical resistance and formability. Taking aviation interior products as an example, in large civil aircraft, a large number of advanced polymer materials are used to manufacture aircraft seat components, table boards, armrests, portholes, sun visors, side wall panels, cargo floor and even luggage rack panels, etc. . In order to meet these application requirements, materials need to have excellent fire performance, such as meeting the 60-second vertical combustion test requirements in FAA25.853, as well as low combustion...
