Abstract

The invention belongs to the technical field of polymer composite materials and relates to a continuous-glass-fibre-reinforced polycarbonate composite material and a preparing method thereof. The composite material is prepared from following components by weight: 100 parts of glass fibre, 1-5 parts of cyclic butylene terephthalate, 0.02-1.0 part of a coupling agent, 0.1-0.5 part of an antioxidant, 0.2-1.0 part of a lubricant and 40-100 parts of polycarbonate. The composite material has high strength and modulus. The composite material is mainly used for high-grade mobile phones, laptops, and other electronic products. In addition, a proper amount of the cyclic butylene terephthalate is added to blend and modify the polycarbonate, and the compatibility between the cyclic butylene terephthalate and the polycarbonate is good, and therefore the fluidity of the polycarbonate is largely improved only by an extremely little amount of addition of the cyclic butylene terephthalate and mechanical properties of the material are hardly influenced.

Description

technical field

[0001] The invention belongs to the technical field of polymer composite materials, and relates to a continuous glass fiber reinforced polycarbonate composite material and a preparation method thereof. Background technique

[0002] Continuous fiber-reinforced thermoplastic is a polymer-based composite material developed in the early 1970s. It consists of a thermoplastic resin matrix, continuous reinforcement fibers and some additives. The resin is evenly distributed among the fibers to form a continuous phase. To fix the spatial position of the fiber and transmit the load inside the material, the resin matrix endows the continuous fiber reinforced thermoplastic composite with excellent mechanical properties, thermal properties, processability and chemical corrosion resistance. Most thermoplastic resins can be used as the resin matrix. Such as polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polyphenylene sulfide (PPS), polyether ether ketone (...
