Description
Technical field
This utility model relates to new material technology field, is specifically related to a kind of carbon fiber thermal insulating material.
Background technology
Carbon fiber (carbon fiber is called for short CF), is the tencel material of a kind of phosphorus content high intensity more than 95%, high modulus fibre.It is to be piled up along fiber axial direction by organic fibers such as flake graphite crystallites to form, the micro crystal graphite material obtained through carbonization and graphitization processing.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than iron and steel, and has corrosion-resistant, the characteristic of high-modulus, is all important materials at defence and military and civilian aspect.It not only has the intrinsic intrinsic property of material with carbon element, has both again the soft machinability of textile fabric, is a new generation's reinforcing fiber.
Carbon fiber tensile strength is about 2 to 7GPa, and stretch modulus is about 200 to 700GPa.Density is about 1.5 to 2.0 grams every cubic centimetre, this except having with precursor structure outside the Pass, depend mainly on the temperature that carbonization processes.General through 3000 DEG C of graphitization processing of high temperature, density is up to 2.0 grams every cube li.Adding its very light in weight, its proportion is also lighter than aluminum, and less than the 1/4 of steel, specific strength is 20 times of ferrum.The thermal coefficient of expansion of carbon fiber is different from other fiber, and it has anisotropic feature.The specific heat capacity of carbon fiber is generally 7.12.Thermal conductivity raises with temperature and declines that to be parallel to machine direction be negative value (0.72 to 0.90), and being perpendicular to machine direction is on the occasion of (32 to 22).The ratio resistance of carbon fiber is relevant with the type of fiber, and when 25 DEG C, high-modulus is 775, and high-strength carbon fiber is every centimetre 1500.This makes carbon fiber have the highest specific strength and specific modulus in all high-performance fibers.Compared with the metal materials such as titanium, steel, aluminum, carbon fiber has the features such as intensity is big, modulus is high, density is low, linear expansion coefficient is little in physical property, is properly termed as the king of new material.The carbon fiber thermal insulating material having satisfactory texture has the hard felt of carbon fiber and carbon-fiber-reinforced felt.The life-span of hard felt is considerably longer than solidification felt, and the heat insulating ability of hard felt is slightly worse than solidification felt or suitable with solidification felt.But the thermal conductivity distributing homogeneity of both traditional carbon fibres insulation materials is poor, easily crystallite and the formation of hard impurity group in induction polycrystalline crystal.To this end, continue to solve the insulation material of the problems referred to above at present.
