Problems solved by technology
Although this technology has the columnar reinforcement performance of the core layer, when the surface layer lacks the composite reinforcement of 0°~90° intersecting continuous fiber prepreg tape with high strength, high toughness, and impact resistance, it cannot achieve high impact resistance and tensile strength under high pressure. Stretching; the honeycomb hollow tube is filled with fillers, and the thin-walled round tube is difficult to bear heavy loads and loses stability and collapses; after the surface layer of the honeycomb hollow tube is damaged, foreign matter enters the honeycomb cavity and is difficult to remove, which increases the weight of its own board and reduces heat insulation. Sound insulation function, etc.

Abstract
The invention relates to the field of loose or adhesive fibrous material reinforced polymer compounds, in particular to a continuous fiber pre-impregnated integrated composite board with a built-in foaming honeycomb body and a manufacturing method thereof. The continuous fiber preimpregnation integrated composite board with the built-in foaming honeycomb body comprises a composite board body (1) and is characterized in that the composite board body (1) is composed of a 0-90-degree continuous cross fiber multilayer pre-impregnated integrated belt panel (11) and a built-in foaming body tubular cellular board (12), and the pre-impregnated integrated belt panel (11) is heated to be directly attached to the built-in foaming body tubular cellular board (12) in a fusion mode to form the compositeboard body (1) with enhanced sound insulation and heat preservation functions. The composite board is simple in structure, convenient to manufacture, low in density and high in strength.
Description
technical field [0001] The invention relates to the field of loose or adhered fibrous material-reinforced polymer compounds, in particular to a continuous fiber prepreg integrated composite board with a built-in foam honeycomb body and a manufacturing method thereof. Background technique [0002] Thermoplastic continuous fiber prepreg tapes have the advantages of high strength, light weight, corrosion resistance, etc., but 0° unidirectional fiber tapes have weaknesses such as anisotropic mechanical properties, and various boards made of 0° unidirectional fiber tapes also have anisotropic mechanical properties. Weaknesses in performance etc. [0003] The upper and lower layers of the honeycomb core are covered with 0°~90° intersecting continuous fiber prepreg strip plate composite, and the surface layer has 0° unidirectional fiber overall with high tensile strength, high impact strength, high toughness, tear resistance, and hollow The honeycomb body greatly reduces the weigh...
