Abstract
The inventive method uses resin adhesive to bond two or more pieces of old carbon brake plates together by curing, charring and chemical vapour deposition processes. The invention adopts the home charcoal bonding process to maintain the airplane carbon brake plate, so its maintain ability has greatly increased.
Description
Technical field
The invention belongs to aviation braking technology field, being specifically related to a kind of is the airplane carbon brake disc integral adhesive maintenance method of bonding matrix with the original position charcoal.
Background technique
Airplane carbon brake disc is a kind of C/C composite product, is the braking material in the airplane brake system, have frictional behaviour steadily, characteristics such as long service life, high temperature resistant, light weight, in aircraft, obtained using widely.Because airplane carbon brake disc belongs to attrition component, and its manufacture cost height, cost an arm and a leg, thereby the maintenance of airplane carbon brake disc utilizes again becomes one of focus that each airline and airplane carbon brake disc manufacturing firm pay close attention to.
Developed a kind of " two-in-one " riveted joint maintenance technique abroad in the early 1990s, old carbon/carbon brake disc can be utilized after keeping in repair again.Because this technological method is simple, and can bring enormous profits, thereby has obtained very fast popularization.
But " two-in-one " riveted joint maintenance technique has following shortcoming:
(1) " two-in-one " riveting technology can only adopt the symmetry maintenance, promptly can only keep in repair the carbon/carbon brake disc with suitable thickness, can not keep in repair the carbon/carbon brake disc of wear and tear more or wearing and tearing/damage pattern complexity, and the utilization ratio again of old carbon/carbon brake disc is low;
(2) carbon/carbon brake disc of " two-in-one " riveted joint maintenance can not continue maintenance after using certain life-span;
(3) former and later two final quotaions in the cover carbon/carbon brake disc are keeped in repair as if employing " two-in-one ", because thin thickness, the rigidity of carbon plate is not enough, after using certain life-span, easily causes carbon/carbon brake disc cracked, has serious potential safety hazard, can only adopt brand-new carbon plate to substitute.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, providing a kind of is the airplane carbon brake disc integral adhesive maintenance method of bonding matrix with the original position charcoal, to have improved the utilization ratio again of crate carbon/carbon brake disc, its theoretical repair rate reaches 100%, simultaneously, the reliability of airplane carbon brake disc maintenance is increased substantially.
For achieving the above object, the technical solution adopted in the present invention is: a kind of airplane carbon brake disc integral adhesive maintenance method is characterized in that this method may further comprise the steps:
(1) with at least two old dishes of airplane carbon brake disc after machining and surface treatment, with phenolic resin or furfural acetone resin and to add weight percentage therein be that 5～20% plumbago is mixed with binder, be coated in old carbon/carbon brake disc surface and carry out bonding;
(2) be placed in the hotpress through the airplane carbon brake disc after the bonding processing in will step (1), be that 120～160 ℃, pressure are under the condition of 10～15MPa in temperature, carries out press curing and handle;
(3) airplane carbon brake disc after overcuring is handled in the step (2) being packed in the normal pressure retort, is under 880～940 ℃ the condition at carbonization temperature, charing 15 hours;
(4) airplane carbon brake disc after handling through charing in the step (3) being packed in the chemical vapor deposition stove, is 880～940 ℃ condition deposit 72 hours in temperature, and bonding interface is carried out the chemical vapor deposition reinforcement;
(5) airplane carbon brake disc through the chemical vapor deposition reinforcement in the step (4) is carried out the machine riveting processing, promptly obtain having the carbon/carbon brake disc service parts of equivalent performance with new carbon/carbon brake disc.
The present invention compared with prior art has the following advantages:
(1) need not to adopt two symmetry maintenances, can take the original position charcoal bonding in aggregates two asymmetric or three old carbon/carbon brake discs, increased substantially the utilization ratio again of old carbon/carbon brake disc, its theoretical maintenance rate can reach 100%;
(2) the bonding asymmetric old carbon/carbon brake disc of original position charcoal is an one, its good heat conductivity, and do not change the friction and wear behavior of former carbon/carbon brake disc, the carbon/carbon brake disc after the maintenance has the working life with new part equivalence;
(3) intensity of original position charcoal bonding interface is higher than the intensity of old carbon/carbon brake disc material body, and its good integrity has improved the operational safety of keeping in repair carbon/carbon brake disc for this reason.
