Flame-retardant prepreg for rail transit
With the requirements for modern rail trains such as lightweight, energy saving and emission reduction, and operational reliability, the application of composite materials in the rail transit industry has gained widespread recognition and support. Rail transit materials made from composite materials are characterized by lightweight, high strength, simple processing, strong designability, resistance to acid and alkali corrosion, and good impact resistance. Currently, they are mainly used to manufacture train fronts, bodies, interior decorations, sanitary facilities, and some track facilities, providing feasible material options for lightweighting in the rail transit field. To meet the development needs of the industry, our company began to apply flame-retardant epoxy resin prepreg, flame-retardant phenolic resin prepreg, and flame-retardant adhesive films to rail transit products in bulk in 2019, and the products can meet the highest fire safety requirements of the rail transit standards DIN5510 and EU EN45545 HL3.
Flame-retardant epoxy prepregs include glass fiber systems, carbon fiber systems, and aramid systems, with resin systems using modified epoxy resins, halogen-free flame retardants, and latent curing agents, providing reliable flame-retardant performance. The prepregs can be formed using autoclave or molding processes, with curing temperatures ranging from 100 to 160°C, offering a wide selection range.
Flame-retardant adhesive films have good bonding strength and are mainly used on the surfaces of rail transit components.
Flame-retardant phenolic prepregs include glass fiber systems, carbon fiber systems, and aramid systems, providing reliable flame-retardant performance. Flame-retardant phenolic prepregs can be formed using autoclave or molding processes and are mainly used for flame-retardant components in rail transit interiors.
