Abstract

The invention provides an impact-resistant flame-retardant floor and a preparation method thereof. The floor comprises an upper panel made of a phenolic resin composite material, an upper bonding layer, a honeycomb core, a lower bonding layer and a lower panel made of the phenolic resin composite material, wherein the above members are sequentially overlapped; and the upper panel and / or the lower panel are / is prepared from phenolic resin prepreg, and preparation raw materials of the upper panel and / or the lower panel comprise phenolic resin and a reinforcing material. The preparation raw materials of the phenolic resin comprise the following components: 0-100 parts of thermoplastic phenolic resin, 0-100 parts of thermosetting phenolic resin, 1-15 parts of a flame retardant, 5-100 parts of a toughening agent, 0.05-1 part of a coupling agent and 0-20 parts of a curing agent, wherein the weight parts of the thermoplastic phenolic resin and the thermosetting phenolic resin are not 0 at the same time. According to the impact-resistant flame-retardant floor, through honeycomb sandwich structure configuration design, forming process design, and toughening and flame-retardant modification on the hot-melt phenolic prepreg, the obtained floor has the characteristics of high impact resistance, flame retardance and low smoke density, and the performance requirements of being used as a passenger and cargo compartment floor material of an airplane are met.

Description

technical field [0001] The invention belongs to the technical field of phenolic resin composite materials, and in particular relates to an impact-resistant and flame-retardant floor and a preparation method thereof. Background technique [0002] The floor of the passenger and cargo compartment of an aircraft is vulnerable to the impact of objects during use, so the mechanical properties such as strength, stiffness, and impact resistance of the plate are required to be high. For example, Airbus A320, A330 and Commercial Aircraft C919 require the bending limit load of long beams on the cargo floor of the bulk area to reach 3000~3500N, and the impact strength requirements reach 14~15J (the surface weight of the sandwich structure is less than 5.8kg / m 2 ). In addition, as an aircraft cabin component, it must also meet the flame retardant requirements of CCAR-25, China's Civil Aviation Regulations, specifically including 60 seconds of vertical combustion, 12 seconds of vertical ...
