Abstract
A carbon (or graphite) fibre fabric reinforced laminated polyether-etherone composition and its preparing process are disclosed. Its advantages are high antiwear and mechanism strength and long service life. It can be used as friction part.
Description
Affiliated field
The present invention has narrated a kind of have high abrasion, high mechanical strength, be suitable for high loading, long lifetime, and severe condition under the carbon fiber that uses or graphite fiber fabric reinforced polyether ether ketone laminar composite and preparation method thereof.
Background technology
Macromolecular material starts from the sixties as friction reducing abrasion resistant material, but its development is very rapid.At present, the application of macromolecular material in friction field more and more widely.Commonly used except that engineering plastics such as nylon and polyphenylene oxide, some novel fire resistant polymer materialss such as polyether-ether-ketone, polyphenylene sulfide and liquid crystalline polymers etc. have appearred in recent years.Because they have good self lubricity, electrical insulating property and damping and amortization are good in addition, thereby are particularly suitable for making dried slide unit.Wherein, the polyether-ether-ketone (be called for short PEEK) with aromatic structure is a kind of noticeable have high temperature resistant, self-lubricating, easy special engineering plastics of excellent properties such as processing and high mechanical strength.
High temperature resistant
The PEEK resin has high glass transition (143 ℃) and fusing point (334 ℃), this be it can be in the purposes that has thermotolerance to require one of reliable reason of using.Its load thermal change type temperature is (30%GF or CF strengthen the trade mark) up to 316 ℃, and use temperature is 260 ℃ continuously.
Mechanical characteristics
The PEEK resin is the plastics that toughness and rigidity have both and average out.Particularly it is the most outstanding in all plastics to the good resistance to fatigue of repeated stress, can match in excellence or beauty with alloy material.
Self lubricity
The PEEK resin has outstanding sliding properties in all plastics, be suitable for being strict with low-friction coefficient and antifriction and consume the way use.Particularly carbon fibre, graphite, tetrafluoroethylene respectively account for the slip trade mark of 10% mixed modification or 30%CF and strengthen the trade mark etc. and be the trade mark with excellent sliding properties.
Chemical proofing (erosion resistance)
The PEEK resin has excellent chemical proofing, in common pharmaceutical chemicals, can dissolve or destroy its vitriol oil that has only, and its erosion resistance and nickel steel are close.
Flame retardant resistance
The PEEK resin is unusual stable polymer, and the sample that 1.45mm is thick does not add any fire retardant and just can reach high flame retardant standard.
Workability
Though the PEEK resin is super heat-resistant resin because it has characteristics such as the good and heat decomposition temperature of temperature flowing is very high, so can adopt injection, extrude, mold pressing, blowing, melt-spinning, rotoforming and powder spraying etc.
Carbon fiber is fibrous carbon material, and promptly carbon accounts for more than 90% of total mass in its chemical constitution.Elemental carbon can form crystal forms such as diamond, graphite, Cabbeen according to the difference of its atom combination, also can form amorphous various transition state carbon.Carbon fibre fabric is with the two dimension of carbon fiber knit or the integral material of 3D shape, and cloth has stable and more not available characteristics of unidirectional fibre of fibre shape.
A series of excellent properties such as carbon fiber strengthens that the thermoplas tic resin composite has that density is little, height ratio strong, height ratio mould, antifatigue, creep resistance, high temperature resistant, corrosion-resistant, wear-resistant, conduction, heat conduction, thermal expansivity are little, self-lubricating and energy-absorbing antidetonation, combine the advantage of carbon fiber and engineering plastics and special engineering plastics, on performance, play synergy, obtain the incomparable superior over-all properties of single-material, become a class novel composite material.At present, carbon fiber enhancing thermoplas tic resin composite has been widely used for defence and military departments such as aerospace, rocket, guided missile, aviation, nuclear power and extensively has been generalized to the product for civilian use.
Summary of the invention
