Problems solved by technology

Relevant research and tests have also been carried out in China. A large number of test results show that: carbon fiber reinforced nylon can increase the tensile strength, flexural strength, flexural modulus, surface hardness, wear resistance, and heat resistance of nylon composite materials. Sassafras coefficient is small, light weight and other advantages, but carbon fiber reinforced materials also have their disadvantages, such as: high cost, poor processability, poor surface finish, etc.

Abstract

The invention discloses a carbon fiber reinforced nylon composite draw-bar box castor .The castor is prepared from nylon, active carbon fibers, EPDM-g-MAH, surface-activated hollow glass micro-beads, a heat stabilizer, an antioxidant and a lubricating agent; the heat stabilizer, the antioxidant, the lubricating agent and the dried nylon, EPDM-g-MAH and surface-activated hollow glass micro-beads are mixed in a high-speed mixer, and a mixture is obtained; the mixture and the active carbon fibers are subjected to injection molding, and the draw-bar box castor is obtained .The carbon fiber reinforced nylon composite draw-bar box castor has the advantages of being high in performance, moderate in cost, easy to form and machine and the like and has a wide industrial application prospect.

Description

technical field [0001] The invention relates to a nylon composite trolley case caster, in particular to a carbon fiber reinforced nylon composite trolley case caster. Background technique [0002] Trolley box caster system materials (including brackets and casters) are produced with reinforced nylon at home and abroad. Nylon is mainly modified by fiber, which can significantly improve the acid and alkali resistance and physical and mechanical properties of nylon, making it applicable to a wider range, so fiber modified nylon is of great significance. Reinforced nylon includes glass fiber reinforced / carbon fiber reinforced / basalt fiber reinforced and aramid fiber reinforced. Among them, glass fiber and carbon fiber are the main types. Glass fiber reinforced nylon is a composite material made of polymer as a matrix and glass fiber as a reinforcing material. It combines the properties of polymer and glass fiber and has high strength and corrosion resistance. , heat insulation...
