▎ 摘 要
NOVELTY - The winding type carbon fiber pipe comprises a prepreg tape which is formed by winding a carbon fiber composite material on a pipe framework through a wet method. The prepreg tape comprises a carbon fiber fabric and prepreg slurry. The prepreg slurry comprises 100 pts. wt. an epoxy resin, 30-40 pts. wt. a curing agent, 10-20 pts. wt. an amino-terminated polysiloxane, 0.5-1 pt. wt. graphene oxide and 0.5-1 pt. wt. carboxylated carbon nanotube. The epoxy resin is a bisphenol A epoxy resin. USE - Winding type carbon fiber pipe. ADVANTAGE - The polysiloxane with the amino-terminated end has good compatibility with the epoxy resin, so that the amino with the polysiloxane reacts with the epoxy group of the epoxy resin, the amino-terminated polysiloxane has excellent dispersion stability in the epoxy resin, and the polysiloxane has excellent flexibility and can effectively improve the performance of the epoxy resin. The carboxylated carbon nanotube can react with the amino group of polysiloxane to generate an amide group, and the amino group of polysiloxane and the hydrogen bond of graphene oxide are utilized to generate a bond, so that the graphene oxide and the carboxylated carbon nanotube are grafted on epoxy resin, and on the premise that the polysiloxane and the epoxy resin have good compatibility, the reinforcing effect of the graphene on the carbon fiber pipe is exerted to the greatest extent. The graphene oxide and the carboxylated carbon nanotube are dispersed in the epoxy resin fully and uniformly. The graphene agglomeration is avoided, the dispersion stability of the prepreg slurry is ensured, and the modulus and the toughness of the cured carbon fiber pipe can be improved. After the graphene and carbon nanotubes are compounded with epoxy resin, the mechanical properties and heat resistance of the carbon fiber tube can be effectively enhanced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a processing technology of the winding type carbon fiber pipe, which involves obtaining the above raw materials of prepreg slurry; uniformly mixing, stirring, carrying out ultrasonic reaction for 2-5 hours, and carrying out vacuum defoaming to obtain a pre-impregnated slurry; pouring the prepreg slurry into a glue dipping tank, placing an ultrasonic generator in the glue dipping tank, dipping the carbon fiber tows into the prepreg slurry, and removing excess resin glue solution through a glue scraping roller; and arranging the carbon fiber tows after the glue dipping on a mold in a winding mode through a filament arranging machine, repeatedly winding to form prepreg cloth, taking the prepreg cloth, and drying.
