Description
Technical field
The present invention relates to a kind of composite material and preparation methods, it is more particularly related to a kind of epoxy resin
Based composites and preparation method thereof belong to Epoxy Resin Technology field.
Background technique
Epoxy resin is a kind of thermosetting resin, because having excellent adhesion, the characteristics such as mechanical strength and electrical insulating property,
And be widely used in adhesive, coating and matrices of composite material etc..But due to pure epoxy resin there are matter crisp, endurance
Property, the disadvantages of heat resistance and shock resistance are poor, be subject to certain restrictions its application.Therefore the modification work to epoxy resin
The heat subject always studied, wherein main Research approach in addition to by adding various toughener, is exactly to utilize inhomogeneity
Combination between type epoxy resin, the combination of different curing agent achieve the purpose that carry out toughening modifying to epoxy resin.
State Intellectual Property Office discloses a Publication No. CN1578799A in 2005.02.09, and entitled " fiber is strong
The invention of the preparation method and fiber reinforced composite material of change composite material composition epoxy resin, fiber reinforced composite material ",
The invention is related to I: the epoxy resin that is at room temperature liquid with (1), (2) are the aromatic polyamine of liquid, (3) diamino at room temperature
Diphenyl sulphone (DPS) be essential component epoxy resin composition for fiber-reinforced composite material, II: containing at least (4) 3 functions or its with
On aromatic epoxy resin, more than (5) 2 functions 3 functions less than aromatic epoxy resin, (6) aromatic polyamine, solidfied material
Theoretical crosslinking points between molecular weight be 250-350g/mol in the range of, and 80 DEG C of initial viscosity be 1~500MPa/s
Epoxy resin composition for fiber-reinforced composite material, III: containing (7) aralkyl-phenol resin more glycidyl ethers,
(8) epoxy resin composition for fiber-reinforced composite material of polyamines.Liquid epoxy resin composition provided by the invention plays
At relatively low temperatures low viscosity, because solidfied material water suction caused by glass transition temperature decline small excellent properties.
Although above-mentioned composite material have at relatively low temperatures low viscosity, because solidfied material water suction caused by vitrifying
Transition temperature declines small excellent properties, but its comprehensive mechanical property is poor.
Summary of the invention
Present invention seek to address that epoxy resin-base composite material in the prior art there are the problem of, a kind of asphalt mixtures modified by epoxy resin is provided
Resin-based composite, the composite material have preferable comprehensive mechanical property.
In order to achieve the above-mentioned object of the invention, specific technical solution is as follows:
A kind of epoxy resin-base composite material, it is characterised in that: including aramid fabric and be coated on aramid fabric
