Description
Technical field
The invention discloses a kind of fibre reinforced polycarbonate composite material, belong to technical field of polymer composite materials.
Background technology
Merlon (being called for short PC) is the high molecular polymer in strand containing carbonate group, can divide according to the structure of ester group
For polytypes such as aliphatic, aromatic series, aliphatic-aromatics.Wherein due to aliphatic and the poly-carbon of aliphatic-aromatic
The mechanical performance of acid esters is relatively low, thus limits its application in terms of engineering plastics.Only have aromatic copolycarbonate at present
Obtain industrialized production.Due to the particularity on polycarbonate structure, become growth rate in five large-engineering plastics
The fastest general engineering plastic.The big application of the three of PC engineering plastics be glazing, auto industry and electronics,
Electrical equipment industry, secondly also have the office equipments such as industrial machinery part, CD, packaging, computer, medical treatment and keep healthy,
Thin film, leisure and protective equipment etc..
For improving the performance of macromolecular material, macromolecular material is modified by expansive approach market, thus improves material and combine
Closing performance, the potential various functions of excavated material are human material's most popular methods of industry, extensively apply in many fields.
Carbon fiber (carbon fiber is called for short CF), is a kind of phosphorus content high intensity more than 95%, high modulus fibre
Tencel material.It is to be piled up along fiber axial direction by organic fibers such as flake graphite crystallites to form, through carbonization and
Graphitization processing and the micro crystal graphite material that obtains.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is high
In iron and steel, and there is corrosion-resistant, the characteristic of high-modulus, be all important materials at defence and military and civilian aspect.It is not
Only there is the intrinsic intrinsic property of material with carbon element, have both again the soft machinability of textile fabric, be a new generation's reinforcing fiber.
Carbon fiber has many premium properties, and the axial strength of carbon fiber and modulus are high, and density is low, higher than performance, without creep,
Superhigh temperature resistant under non-oxidizing atmosphere, fatigue durability is good, specific heat and electric conductivity between nonmetal and metal, thermal expansion system
Number is little and has anisotropy, good corrosion resistance, and X-ray transparent is good.Good electrical and thermal conductivity performance, electromagnetic shielding
Property good etc..
At present, the research of existing a large amount of carbon fibre reinforcements, but often there are some defects, as product strength is low,
Density is big, it is impossible to give full play to the advantage that carbon fiber is compound.
