Abstract
The utility model discloses a novel composite material skin cementing and repairing structure. The novel composite material skin cementing and repairing structure comprises an outer pasting and repairing sheet arranged at the outer side of a composite material skin damage area, wherein the inner side of the composite material skin damage area is provided with an inner pasting and repairing sheet; the geometric shape of the inner pasting and repairing sheet is similar to that of the outer pasting and repairing sheet, and the area of the inner pasting and repairing sheet is greater than that of the outer pasting and repairing sheet; the geometric center of the inner pasting and repairing sheet is coincided with that of the outer pasting and repairing sheet. The novel composite material skin cementing and repairing structure which is provided by the utility model can be suitable for the situation that the composite material skin damage is deep, and the damage area is removed without a through hole mode; moreover, the composite material skin repairing area can reach the requirements of intensity, rigidity and service life.
Description
Technical field
The utility model patent relates to a kind of novel composite material skin Bonding Repair technology.
Background technology
By adhesive bonding of composites, repair the extensive use of composite material skin Yi airline, Fig. 1 (a) and Fig. 1 (b) are the technical schemes of composite material skin Bonding Repair conventional in prior art, adopt the upper outside composite sticking patch 2 that subsidizes of composite material skin 1, this common composite material skin Bonding Repair technical scheme only limits to the not dark situation of composite material skin 1 damage, and common Bonding Repair just can meet intensity and life-span occasion.Darker for some composite material skin damage, but be unlikely to remove by through-hole form the situation of damage completely, if adopt common Bonding Repair technical scheme to be difficult to reach intensity, rigidity and the life requirements after repairing.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of novel composite material skin Bonding Repair structure, go for composite material skin damage darker, but the situation of damage zone being removed completely without through-hole form, and composite material skin repairing district can reach intensity, rigidity and life requirements.
In order to solve the problems of the technologies described above, a kind of novel composite material skin Bonding Repair structure of the utility model, comprise the outer sheet that subsidizes that is arranged on composite material skin damage field outside, in being provided with, the inner side of described composite material skin damage field subsidizes sheet, geometry and the described outer geometry of subsidizing sheet of in described, subsidizing sheet are similar figures, and the area that subsidizes sheet in described is greater than the described outer area that subsidizes sheet.
A kind of novel composite material skin Bonding Repair structure of the utility model, the geometric center of subsidizing sheet in described overlaps with the described outer geometric center of subsidizing sheet.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopt the damage field in composite material skin be provided with simultaneously for glued joint outer subsidize sheet and in subsidize sheet, by one li of one outer damage field that is side by side glued to composite of two sticking patch, compare with existing common Bonding Repair, covering inner surface has increased a composite sticking patch that plays booster action, thereby improved composite material skin, repair the strength and stiffness in district, improved the life-span in composite material skin repairing district simultaneously.
Accompanying drawing explanation
Fig. 1 (a) is the stereogram of common composite material skin cementing structure in prior art;
Fig. 1 (b) is the side view of common composite material skin cementing structure shown in Fig. 1 (a);
Fig. 2 (a) is the stereogram of the utility model composite material skin cementing structure;
Fig. 2 (b) is the side view of advanced composite material (ACM) covering cementing structure shown in Fig. 2 (a).
In figure: 1-composite material skin, 2-subsidizes sheet outward, subsidizes sheet in 3-.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, technical solutions of the utility model are described in further detail.
As shown in Fig. 2 (a) and Fig. 2 (b), a kind of novel composite material skin Bonding Repair structure of the utility model, comprise the outer sheet 2 that subsidizes that is arranged on composite material skin 1 damage field outside, in being provided with, the inner side of described composite material skin 1 damage field subsidizes sheet 3, geometry and the described outer geometry of subsidizing sheet 2 of in described, subsidizing sheet 3 are similar figures, for subsidize outward sheet 2 and in subsidize sheet 3 geometry do not limit, such as can be square, circular and oval etc., the geometric center of subsidizing sheet 3 in described overlaps with the described outer geometric center of subsidizing sheet 2, and the area that subsidizes sheet 3 in described is greater than the described outer area that subsidizes sheet 2.
It is darker that the utility model goes for composite material skin damage, but the situation of damage zone being removed completely without through-hole form, by inside and outside adopting, subsidize mode, by subsidize outward sheet 2 and in subsidize the both sides that sheet 3 is glued to composite material skin 1 damage field, reach intensity, rigidity and the life requirements of composite material skin being repaired to district.
Although by reference to the accompanying drawings the utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that not departing from the utility model aim, can also make a lot of distortion, within these all belong to protection of the present utility model.
Claims (2)
1. a novel composite material skin Bonding Repair structure, comprise the outer sheet (2) that subsidizes that is arranged on composite material skin (1) outside, it is characterized in that, in being provided with, the inner side of described composite material skin (1) subsidizes sheet (3), geometry and the described outer geometry of subsidizing sheet (2) of in described, subsidizing sheet (3) are similar figures, and the area that subsidizes sheet (3) in described is greater than the described outer area that subsidizes sheet (2).
