Embodiment 1
[0016] Raw materials: carbon fiber reinforced material (T700SC-12K) with a volume ratio of 56%, epoxy resin (E44) with a volume ratio of 40%, dimethylaminopropylamine (DEAPA) with a volume ratio of 2%, and a volume ratio of 1% Tri-tertiary aminophenol (DMP-30) and carboxyl-terminated hyperbranched polyester (HBP-SA) with a volume ratio of 1%.
[0017] Specific preparation method:
[0018] (1) Mix the raw materials according to the above volume ratio, so that the resin is firmly combined with the carbon fiber through the impregnation and pre-curing process to form a carbon fiber tow;
[0019] (2) Braiding the carbon fiber tow in step (1) into a rope by using the rope weaving method to form a twisted cable;
[0020] (3) Put the twisted cable into the curing furnace for secondary curing. The temperature of the curing furnace is controlled at 200°C, and the curing time is at least 4 hours;
[0021] (4) Install the twisted cable after secondary curing in step (3) on the yarn carr...
Embodiment 2
[0024] Raw materials: carbon fiber reinforced material (T700SC-12K) with a volume ratio of 61%, epoxy resin (E44) with a volume ratio of 35%, dimethylaminopropylamine (DEAPA) with a volume ratio of 2%, and a volume ratio of 1% Tri-tertiary aminophenol (DMP-30) and carboxyl-terminated hyperbranched polyester (HBP-SA) with a volume ratio of 1%.
[0025] Concrete preparation method: with embodiment 1
Embodiment 3
