The equipment bay includes an equipment bay framework on either side of which skirt panels are typically mounted, which panels may be opened or closed relative to one another to open or close the equipment bay.
The present invention provides a composite skirt panel comprising at least an outer panel 1 and a honeycomb structure 2. It should be noted that the side of the skirt panel facing the environment outside the vehicle is defined as the outside, and correspondingly, the side of the skirt panel facing the equipment compartment space is defined as the inside.
The outer panel 1 is typically a panel formed using a carbon fiber composite material. Of course, other materials may be used and the thickness of the outer panel 1 may be approximately 1mm or so.
The honeycomb structure 2 of the present invention is positioned inside the outer panel 1, and the honeycomb structure 2 comprises at least two honeycomb layers, each of which comprises a plurality of honeycomb cells, wherein the honeycomb cell is the smallest unit forming a honeycomb, and the cross-sectional area of the honeycomb cell can be circular, or can be a regular polygon, such as a regular quadrangle, a regular pentagon, a regular hexagon, or the like.
Each honeycomb cell extends generally in an outside-in direction, that is, the honeycomb cells of each honeycomb layer extend generally in an outside-in direction in the present invention. The solution is preferably such that the through-holes of the honeycomb cells are axially perpendicular to the corresponding mounting surface of the outer panel 1.
In the invention, all honeycomb layers are arranged from outside to inside in sequence, and the rigidity of the honeycomb layer close to the outer panel 1 is higher than that of the honeycomb layer positioned at the inner side of the honeycomb layer.
The honeycomb structure 2 in the composite skirtboard comprises a plurality of honeycomb layers with different rigidity, rigidity gradient exists among the honeycomb layers, and the rigidity of the honeycomb layer is larger as the honeycomb layer is closer to the outer panel 1, so that the rigidity of the honeycomb layer close to the outer panel 1 is maximum, the strength of the position where the outermost honeycomb layer is combined with the outer panel 1 is also strongest, the impact resistance of the outer panel 1 is favorably improved, the service life of the outer panel 1 is greatly prolonged, and the maintenance cycle of the skirtboard of the vehicle is prolonged. And the honeycomb cells extend in the direction from outside to inside, so that the impact resistance of the skirting board is further improved.
And the rigidity of the honeycomb is smaller closer to the inner layer, so that the use strength of the skirtboard is ensured, the whole weight of the composite skirtboard is reduced, and the lightweight setting requirement is met.
The rigidity of the honeycomb layer can be different by designing honeycomb cells with different shapes, and can be realized by arranging the honeycomb cells with the same shape but different sizes. A specific embodiment is given below.
In a specific embodiment, the side lengths of the cell cells of the cell layer increase stepwise from the outside to the inside. Specifically, taking the example of including two honeycomb layers, for the sake of simplicity of the technical solution, the two honeycomb layers are defined as a first honeycomb layer 21 and a second honeycomb layer 22, the first honeycomb layer 21 is located outside the second honeycomb layer 22, the outer wall of the first honeycomb layer 21 is in contact with the outer panel 1 and may be fixed by an adhesive, and the inner wall is fixed to the second honeycomb layer 22.
The honeycomb cell through holes of the first honeycomb layer 21 and the second honeycomb layer 22 are axially approximately parallel, and the outer contour dimension of the through hole of the first honeycomb layer 21 is smaller than that of the through hole of the second honeycomb layer 22.
By designing the cell side lengths of the respective cell layers to be different sizes, a stiffness gradient can be formed between the respective cell layers. Namely, the side lengths of the honeycomb cells of the honeycomb layers from outside to inside are gradually increased, so that the rigidity of each honeycomb layer is gradually reduced from outside to inside.
The above-described manner of setting different cell sizes is simple and easy to implement.
As described above, the outer side surface of the outermost honeycomb layer and the outer panel 1 are fixedly bonded by the adhesive, and the shear strength of the adhesive may be not less than 20Mpa and the 90 ° peel strength may be not less than 26N/cm at room temperature. The 90 ° peel strength here refers to the peel strength of the outer panel 1 from the honeycomb layer. The room temperature condition is usually about 25.
The adhesive has good toughness and durability. It can be cured at room temperature or heated to 60-90 deg.C.
In view of reducing the use cost of the composite skirtboard as much as possible, the technical scheme can also be arranged as follows.
In a specific embodiment, the outer side wall of the outermost honeycomb layer and the outer panel 1 are fixedly connected by adhesive bonding to form an integral composite layer, and the performance of the adhesive can be referred to as described above. The adhesive may be of the epoxy or modified epoxy type. The outermost honeycomb layer after bonding is usually formed as a very strong integral body with the outer panel 1.
And the inner side wall of the honeycomb layer in the integral composite layer is detachably connected with the adjacent inner side honeycomb layer. Like this when compound skirtboard uses the impaired back of panel 1 outside a period, can earlier outer panel 1 and outside honeycomb layer form whole from rather than adjacent inboard honeycomb layer dismantlement, directly change new outer panel 1 and outside honeycomb layer can, need not to change holistic skirtboard completely, saved the use cost of skirtboard greatly.
In a preferred embodiment, the through holes of the honeycomb cells of each honeycomb layer are axially approximately parallel and perpendicular to the outer panel 1, and a partition 23 is further disposed between adjacent honeycomb layers, and the surface of each honeycomb layer facing the partition 23 is fixed to the partition 23 by a bonding process. The size of the partition 23 is about the same as the size of the side face of the honeycomb layer, and the openings at the two sides of the cell through holes of the honeycomb layer respectively face the partition 23 at the two sides and are blocked by the partition 23 at the two sides. Therefore, the service strength of the honeycomb layer is greatly improved, and the honeycomb cells of two adjacent layers are prevented from being embedded into each other.
The thickness of the partition 23 in the above embodiment may be thin, preferably 0.4mm to 0.7 mm.
In the above embodiments, the inner panel 4 may be provided inside the innermost honeycomb layer, or the inner panel 4 may not be provided. The figure shows an embodiment in which the inner panel 4 is provided. The inner panel 4 and the outer panel 1 enclose a cavity together, the honeycomb structure is arranged in the cavity, and the honeycomb layer positioned at the innermost side is bonded and fixed with the inner panel 4 through an adhesive.
In the above embodiment, the material of each honeycomb layer is an aluminum alloy material or a material having a crushing rigidity smaller than that of the outer panel 1.
In the above embodiments, in order to further increase the local use strength of the outer panel 1, the inside of each cell of the outermost honeycomb layer is filled with one or more of PU foam, PMI foam, or aluminum foam.
In particular, the PU foam is extremely lightweight, and does not increase the overall weight of the skirt panel while increasing the use strength of the outer panel 1 side.
If foamed aluminum is used, the foamed aluminum preferably has a closed cell structure and a density of 200 to 500kg/m 3.
