Abstract
The invention discloses a kind of modified graphene/fibre reinforced composites and preparation method thereof, its composition is made up of 2 3% graphenes, 70 80% fibers and 20 30% resins, according to the purposes of product, and be heating and curing shaping in equipment and mold.Its feature is that product strength is high, and good toughness is lightweight, is widely used in the fields such as big machinery, chemical plant installations, hydraulic engineering, road traffic, architectural engineering, ocean engineering, power engineering.
Description
Technical field
The invention belongs to field of compound material in new material, more particularly to a kind of modified graphene/fiber-reinforced composite material
Material.
Background technology
Graphene（Graphene）It is the only one layer of atomic thickness for being stripped out, being made up of carbon atom from graphite material
Two dimensional crystal.2004, Univ Manchester UK physicist An Deliegaimu and Constantine's Nuo Woxiao loves,
Graphene is isolated in success from graphite, it was demonstrated that it can be with individualism, and therefore two people also obtain Nobel's thing in 2010 jointly
Neo-Confucianism prize.
Graphene is both most thin material, is also most tough material, fracture strength more taller than best steel 200
Times.It has good elasticity again simultaneously, and stretch range can reach the 20% of own dimensions.It is that current nature is most thin, intensity most
High material, if making hammock with the graphene of one piece of 1 square metre of area, weight itself just can bear one less than 1 milligram
Only one kilogram of cat.
Fibrous composite belongs to polymer composite, and it is to be placed in matrix material as reinforcement by various fibers to answer
Conjunction is formed.Wherein high-performance fiber refers to have high tensile strength and compressive strength, abrasion-resistant, high damage-resistant power, low-gravity
(g/m3) fibrous material of excellent physical property such as, it is that the class quickly grown in recent years in polymeric fibrous material field is extraordinary
Fiber, composite is compared with traditional material, with higher specific strength, chemicals-resistant and resistance to sudden heating, and bigger
Design flexibility.
Because prior art is that fiber is molded with resin thermosets, the tensile strength of its product, modulus of elasticity are low, be produced into
This height, does not give full play to optimal effect, and some key projects, field are still with traditional metal material, perishable, matter
Amount weight, operating cost is high, the shortcomings of labor intensity is big.
The content of the invention
In order to solve to there is now the problems of technology, it is modified and sets it is an object of the invention to provide a kind of modified graphene
Fat/fibrous composite, can improve the tensile strength and modulus of elasticity of product, and elongation further reduces production cost and people
The labor intensity of member.
In order to realize above-mentioned purpose, the present invention uses following technical scheme：A kind of modified graphene/fiber-reinforced composite
Material and preparation method thereof, its composition is made up of 2-3% modified graphenes, 70-80% fibers and 20-30% resins, according to product
Purposes, be heating and curing shaping in equipment and mold.
The material prepared using the method for the present invention：Pipe, rod, plate and muscle material tensile strength and modulus of elasticity, through experiment
As a result more than 30% can be improved, elongation can improve more than 10%.
