Problems solved by technology

Unsaturated polyester has poor mechanical properties and cannot be used in some occasions that require high mechanical properties, and the curing agent is peroxide, which is flammable and explosive, and processing has certain dangers
Epoxy resin is a high-performance resin, but its price is expensive, its curing speed is slow, and because of its high cross-linking, the material is hard and brittle, and its toughness is insufficient

Abstract

The invention relates to a formula for synthetizing a protein-bound iodine (PBI) fiber composite material. The PBI fiber composite material is prepared from the following components in parts by weight: 100 parts of PBI fibers, 0-2 parts of a catalyst, 15-30 parts of isocyanate, 13-44 parts of polymer polyol, 0-1 part of a defoamer, and 0-1 part of a filler. The composite fiber material is prepared from continuous PBI fibers infiltrated by polyurethane resin. The enhanced material disclosed by the invention is good in wettability on the PBI fiber, fast to mold in solidification, high in crosslinking degree, and good in mechanical property.

Description

technical field [0001] The invention relates to a technical formula of a polymer fiber composite material, in particular to a formula for synthesizing a PBI fiber composite material. Background technique [0002] PBI is the abbreviation of polybenzimidazoles, the English name is Polybenzimidazoles, which belongs to amorphous special engineering plastics. PBI is a high-performance resin material jointly developed by NASA and the U.S. Air Force Materials Laboratory. It has excellent high temperature resistance, low temperature resistance, mechanical properties and flame retardancy, as well as wear resistance, radiation resistance, Acid and alkali resistant, it is a high-performance resin material with great application prospects. Its application fields involve aerospace, optics, microelectronics and many other high-tech fields. With the needs of technological development, the application field of PBI has gradually shifted to civilian use. However, due to the poor axial tensi...
