Embodiment 1

[0016] Weigh 48 parts of ceramic fiber, 25 parts of viscose fiber, and 2 parts of spinning aid, and put the spinning aid into warm water at 35° C. to dilute at a ratio of oil:water=1:5. Mix the ceramic fiber and viscose fiber evenly. After the mixing is completed, spray the diluted additive evenly and store it for 12 hours. After the silo is completed, 13 parts of glass fiber spun yarn are added. At this time, 500Tex (Tex) fiber yarn is formed by twisting, and 12 parts of copper wire are added for plying, then twisted to form 1800Tex fiber yarn, and passed through the doffer Form cheese and use weaving equipment to produce fiber cloth for friction materials. The warp density of this product is 56 threads / 10cm, the weft density is 26 threads / 10cm, and the bulk density is 500Kg / m 3 , the organic content of the fiber cloth is 28%, the moisture regain of the product is 2.5%, and the main component in the product is Al 2 o 3 : 16%, SiO 2 : 47%, metal: 17%, loss on ignition: 20%....

Embodiment 2

[0018] Weigh 50 parts of ceramic fiber, 25 parts of flame-retardant fiber, and 2 parts of spinning aid, and put the spinning aid into warm water at 40° C. to dilute at a ratio of oil:water=1:6. Mix the ceramic fiber and flame retardant fiber evenly. After the mixing is completed, spray the diluted additive evenly and keep it in a silo for 16 hours. After the silo is completed, 13 parts of carbon fiber are added. At this time, 600Tex (Tex) fiber yarn is formed by twisting, and then twisted and 12 parts of glass fiber yarn are plied to form 1850Tex fiber yarn, which is then doffed The machine forms cheese, and uses weaving equipment to produce fiber cloth for friction materials. The warp density of this product is 60 pieces / 10cm, the weft density is 30 pieces / 10cm, and the bulk density is 530Kg / m 3 , the organic matter content of the fiber cloth is 27%, the moisture regain of the product is 1.9%, and the main component in the product is Al 2 o 3 : 17%, SiO 2 : 36%, metal: 12%...

Embodiment 3

[0020] Weigh 55 parts of ceramic fiber, 25 parts of flame-retardant fiber, and 3 parts of spinning aid, and put the spinning aid into warm water at 37° C. to dilute at a ratio of oil:water=1:8. Mix the ceramic fiber and flame retardant fiber evenly. After the mixing is completed, spray the diluted additive evenly and keep it in a silo for 15 hours. After the silo is completed, add 10 parts of aramid spun yarn. At this time, the fiber yarn of 550Tex (Tex) is formed by twisting, and then twisted and 15 parts of steel wire are added to form a fiber yarn of 1100Tex, and the bobbin is formed through the doffer Yarn, and weaving equipment is used to produce fiber cloth for friction materials. The product has a warp density of 55 threads / 10cm, a weft density of 22 threads / 10cm, and a bulk density of 430Kg / m 3 , the organic content of the fiber cloth is 32%, the moisture regain of the product is 2.5%, and the main component in the product is Al 2 o 3 : 18%, SiO 2 : 42%, metal: 15%,...

Abstract

The cloth for friction material belongs to friction material for brake. The present invention features that ceramic fiber as base material, one or several kinds of reinforcing fiber and assistant are produced into the cloth for friction material through opening, carding, roving, finespun, plying, spooling, weaving and other steps. The cloth for friction material consists of ceramic fiber 50-63 weight portions, reinforcing fiber 24-36 weight portions, metal fiber 12-17 weight portions, and assistant 0-2 weight portions. The present invention has effectively raised heat resistance of the friction material, and this results in safety performance of corresponding vehicle and equipment.

Description

technical field [0001] The invention belongs to friction materials for brakes, in particular to a cloth for friction materials. Background technique [0002] Friction materials are critical safety components in clutch assemblies and brakes in vehicles and machinery. It is generally composed of three parts: binder, fiber reinforced material and filler. Traditional fiber reinforced materials mainly include: asbestos fiber, fiber sepiolite, acicular wollastonite, rock wool, glass fiber, steel fiber, copper fiber, aluminum fiber, aramid fiber, carbon fiber, etc. [0003] Asbestos-free friction materials are the current development trend of friction materials. [0004] Non-asbestos friction materials include semi-metal friction materials, NAO friction materials, mixed fiber friction materials, powder metallurgy friction materials and carbon fiber friction materials. The semi-metallic friction material usually contains about 30%-40% iron metal (steel fiber, reduced iron powder,...
