Abstract

The invention relates to a manufacturing method of a fiber-reinforced light fireproof composite material. Carbon fibers, aramid fibers, basalt fibers, glass fibers and silane coupling agent are used as raw materials. According to the manufacturing method, various cutting-off lengths are controlled to be within the range of 100mm +/- 20mm, the silane coupling agent is added for surface processing, the fibers are mixed in proportion after surface processing, and then processes of carding, net laying, needle piercing, rolling, spraying, drying, cooling, coiling and the like are carried out. Through the manufacturing method of the fiber-reinforced light fireproof composite material, solidification of phenolic aldehyde glue is guaranteed, the roller spacing can be adjusted through the processes of rolling and cooling, and a fiber mat suitable for a 3D structure in the fiber-reinforced light fireproof composite material is manufactured.

Description

technical field [0001] The patent of the present invention relates to a reinforcing fiber, especially a 3D structural fiber, more specifically a 3D structural reinforcing fiber felt in a lightweight fireproof composite material. Background technique [0002] At present, the new materials used in domestic and foreign aerospace, rail transit, ships and other fields all require excellent properties such as light weight, high strength, fire prevention, and greenness. Among them, PMI (polyimide foam material), PF (phenolic foam material) ) The two materials are particularly special, with high service temperature, non-combustible fire resistance, green lightweight materials, and the density can not exceed 0.2, but other mechanical properties cannot meet the requirements. Only by reinforcing the above two foam materials with fibers can the problem of poor mechanical properties of PMI and PF foam materials be solved. For example, phenolic foam is a new type of fireproof and heat pr...
