Abstract
The invention discloses a carbon fiber-enhanced PMMA-PA66 alloy material, which is composed of the following substances by weight: 15-50% of carbon fiber, 30-60 parts of PA66, and 20-50 parts of PMMA. In the composite material provided by the invention, carbon fiber is added so as to substantially raise rigidity and toughness of the composite material. When the content of carbon fiber is 25%, the elastic modulus and the flexural modulus of the composite material are greatly raised, and are respectively raised 310% and 328%; the tensile strength and the bending strength are substantially raised, and are respectively increased 262% and 239%; and the impact strength is obviously raised, and is increased 325%.
Description
Technical field
The present invention relates to composite alloy material field, be specifically related to a kind of carbon fiber reinforced PMMA-PA66 alloy material.
Background technology
Carbon fiber is a kind of novel material of mechanical property excellence, and its proportion is less than 1/4 of steel, and carbon fiber resin composite material tensile strength all more than 3500MPa, is generally 7 ~ 9 times of steel, and tensile modulus of elasticity is 230 ~ 430GPa, also higher than steel.
Nylon 66 is a kind of broad-spectrum engineering plastics, because of its higher crystallinity, and more excellent mechanical property, the industries such as low-temperature performance is good, stable chemical performance is widely used in automobile, electronic apparatus, chemical industry, mechanical device instrument, building.Development and each field improving constantly material requirements along with economic technology, nylon 66/ carbon-fibre composite can also give material other special performances when improving material mechanical performance, have a wide range of applications, be more and more subject to people's attention.
Summary of the invention
The present invention adopts carbon fiber to carry out modification to PMMA-OA66 mechanical blending material, obtains all reasonable matrix materials of rigidity and toughness, makes it be applied to widely the fields such as automobile, chemical industry.
Carbon fiber reinforced PMMA-PA66 alloy material, comprises that following materials in part by weight forms:
Carbon fiber 15-50%
PA66 30-60%
PMMA 20-50%
A preparation method for carbon fiber reinforced PMMA-PA66 alloy material, preparation process is as follows:
(1) PA66, PMMA are mixed by weight in high-speed mixer, be then placed in the dry 24h of vacuum drying oven of 80 ℃ to constant weight, obtain raw material A.
(2) surface treatment of carbon fibers agent by deionized water and silane coupling agent take mass ratio as 8:2 formulated, with fiberglass surface treating agent, soak the carbon fiber 12 hours that diameter is 10-15 micron, then be placed in the dry 12h of vacuum drying oven of 60 ℃ to constant weight, obtain raw material B.
(3) then step (2) gained raw material is added to raw material B in twin screw extruder adds fine mouthful, in major ingredient mouth, add raw material A, so latter two sample extruding pelletization after melt blending in forcing machine.
(4) by extruding, the matrix material particle that obtains after pelletizing at 60 ℃ vacuum for dry 12h in case until constant weight just obtains glass fibre reinforced PMMA-PA66 alloy material.
Positively effect of the present invention is: adding of carbon fiber, has improved rigidity and the toughness of matrix material significantly.When the fine content of carbon is 25%, Young's modulus and the modulus in flexure of matrix material are greatly improved, and have improved respectively 310% and 328%; Tensile strength and flexural strength significantly improve, and have increased respectively 262% and 239%; Shock strength is also significantly improved, and has increased by 325%.
