Abstract

The invention provides an impact-resistant and flame-retardant floor and a preparation method thereof. The floor includes: an upper panel of a phenolic resin composite material, an upper adhesive layer, a honeycomb core, a lower adhesive layer, and a phenolic resin composite material that are laminated in sequence. The lower panel; the upper panel and / or the lower panel are prepared by phenolic resin prepreg, and its preparation raw materials include phenolic resin and reinforcing materials, and the preparation raw materials of phenolic resin include the following components: 0-100 parts of thermoplastic phenolic resin, thermal 0-100 parts of solid phenolic resin, 1-15 parts of flame retardant, 5-100 parts of toughening agent, 0.05-1 part of coupling agent, 0-20 parts of curing agent; thermoplastic phenolic resin and thermosetting phenolic resin Resins are not at 0 parts at the same time. The impact-resistant and flame-retardant floor adopts honeycomb sandwich structure configuration design, molding process design, toughening and flame-retardant modification of hot-melt phenolic prepreg, so that the obtained floor material has high impact resistance and flame retardancy. The characteristics of non-toxicity and low smoke density meet the performance requirements of being used as the floor material of the passenger and cargo compartment of the aircraft.

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 ...
