Abstract: The disclosure provides a forming method of a halogen-free flame-retardant material. The method includes the followings. A twin-screw extruder including a first zone and a second zone is used. A mixture in the first zone is mixed, melted and heated to form a molten mixture. The mixture includes a halogen-free flame retardant, a wear-resistant modifier, a thermoplastic elastomer, and an antioxidant. In addition, a silane-modified nano-silica aqueous suspension is introduced into the second zone to mix the silane-modified nano-silica aqueous suspension with the molten mixture from the first zone. The first zone and the second zone are continuously connected regions.

Abstract: A composite material and a foam prepared from the composite material are provided. The composite material includes a network polymer, a fluorine-containing polymer fiber, and a reinforcement fiber. The polymer network is a crosslinking reaction product of a polymer and an oligomer, wherein the polymer is polyamide, polyester, polyurethane, or a combination thereof, and the oligomer is a vinyl aromatic-co-acrylate oligomer with an epoxy functional group. The oligomer has a weight percentage of 1% to 10%, based on the weight of the network polymer. The ratio of the weight of the reinforcement fiber to the total weight of the network polymer and the fluorine-containing polymer fiber is from 1:9 to 4:6.
