Problems solved by technology

However, none of the existing materials can fully meet all the above requirements
[0003] Traditional sound and heat insulation materials can meet the requirements of heat preservation, heat insulation and sound insulation, but they have a high density (about 100-150kg / m 3 ), the use of large-scale laying will inevitably increase the weight of the carriage, which will affect the driving speed and energy consumption, and increase the operating cost
In addition, although the existing sound insulation and heat insulation materials are flame retardant and can prevent the spread of fire, high temperature will cause thermal melting of such materials, and the high temperature droplets produced by thermal melting will burn the skin and clothing, and cause secondary damage to personnel. secondary injury, and it is easy to produce toxic smoke, causing choking, suffocation and even death

Abstract

The invention discloses a carbon fiber high molecular composite material and a preparation method thereof. The composite material is prepared from the following components in parts by weight: 48-55 parts of preoxidized fibers, 17-25 parts of high melting point polyester fibers and 48-55 parts of aramid fibers. By taking the preoxidized fibers, the high melting point polyester fibers and the aramidfibers as raw materials, the high melting point polyester fibers play a good adhesive role during heat-setting. The prepared composite material is light in weight, low in heat conducting coefficient,good in heat insulation, heat preservation and cold prevention property, good in sound isolating and sound absorbing property and flame-retardant and fireproof. The composite material is incombustible and unmeltable in an open fire (blue flame), free of dripping and safe and environmental-friendly, and can be widely applied to special fields such as high speed rain compartments, special garments(for example, firefighter uniform interlayer, polar region cold protective clothing interlayer), occasions needed to be silent and to reduce noise and the like.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a carbon fiber polymer composite material and a preparation method thereof. Background technique [0002] High-speed rail, subway, etc. have strict requirements on the required materials, and often need to meet the requirements of heat insulation, heat preservation, cold resistance, sound insulation, noise reduction, and fire prevention. However, none of the existing materials can fully meet all the above requirements. [0003] Traditional sound and heat insulation materials can meet the requirements of heat preservation, heat insulation and sound insulation, but they have a high density (about 100-150kg / m 3 ), the use of large-scale laying will inevitably increase the weight of the carriage, which will affect the driving speed and energy consumption, and increase the operating cost. In addition, although the existing sound insulation and heat insulation materials a...
