The present invention relates to the field of panels and methods for fabricating panels, and more particularly to panels for a shower or a bathtub and methods for fabricating panels for a shower or a bathtub
Usual panels for shower or bathtubs are made of several layers of different layers. One of these layers is a reinforcement layer used to provide strength to the panel. The reinforcement layer is usually made of wood or surrogate. However, such materials are susceptible to moisture which can adversely impact the adhesion of the wood or surrogate to the adjacent layers. Furthermore, wood or surrogate may not be flexible enough to conform to the contour of a typical bathtub or shower.
Some prior art panels comprise a reinforcement layer made of Balsa. While it improves the flexibility of the panel with respect to other wood and surrogate, Balsa is still susceptible to moisture.
Therefore, there is a need for an improved panel for bathroom applications.
According to a first broad aspect, there is provided a panel comprising: a backing layer having a back face and a front face opposite to the back face, the backing layer being made of polyester resin; an intermediary layer attached to the backing layer; and a surface layer attached to the intermediary layer, the surface layer being made of acrylic modified isophthalic gelcoat.
In one embodiment, the backing layer is made of ArmorCore™.
In one embodiment, the surface layer is made of AcrylX™.

Further features and advantages of the present invention will become apparent from the following detailed description, taken in combination with the appended drawings, in which:
It will be noted that throughout the appended drawings, like features are identified by like reference numerals.
There is described a panel for a bathtub or a shower that comprises at least three layers of different materials. The panel may be part of a shower such as a shower wall, ceiling or base, a bathtub, a bathroom sink, etc. For example, the panel may be shaped so as to correspond to a bathtub.
The layer 12 is the back layer which acts as a support layer for the other layers 14 and 16 and provides the structural shape and strength for the panel 10. The layer 102 is the top of surface layer which will be apparent to a user. The intermediary layer 14 is sandwiched between the top layer 12 and the back layer 16. The intermediary layer 14 provides strength and structure for the panel 10.
The back layer 12 extends between a back face 18 and a top face 20 and the distance between the two faces 18 and 20 defines the thickness of the back layer 12. In one embodiment, the back layer 12 is adapted to be secured to a receiving surface such as a wall or a floor. The intermediary layer 14 extends between a bottom face 22 and a top face 24 and the distance between the two faces 22 and 24 defines the thickness of the intermediary layer 14. The bottom face 22 of the intermediary layer 14 is attached to the top face 20 of the back layer 12. The top or surface layer 16 extends between a bottom face 26 and a top face 28 and the distance between the two faces 26 and 28 defines the thickness of the top layer 16. The bottom face 26 of the top layer 16 is attached to the top face 24 of the intermediary layer 14. The top face 28 of the top layer 16 corresponds to the top surface of the panel 10, which is to be exposed to a user when the panel 10 is installed.
The back layer 12 is made of polyester resin. In one embodiment, the back layer is made of ArmorCore™.
The intermediary layer 14 is made of polymer. In one embodiment, the intermediary layer is made of fiber-reinforced polymer. The intermediary layer may also be made of polyester or fiberglass and/or resin.
It should be understood that the intermediary layer 14 may comprise more than one intermediary layers deposited one on top of the other between the layers 12 and 16. The different intermediary layers may be made of the same material or of different materials.
The top layer 16 is a layer made of acrylic modified isophthalic gelcoat. In one embodiment, the top layer 16 is made of AcrylX™.
In one embodiment, the panel 10 further comprises an additional layer attached to the back face 18 of the layer 12. In this case, the back face of the additional layer is adapted to abut a panel-receiving surface such as a wall, a floor or a ceiling of a bathroom.
The additional layer is made of polymer. In one embodiment, the additional layer is made of fiber-reinforced polymer. The additional layer may also be made of polyester or fiberglass and/or resin.
In one embodiment, the additional layer is made of the same material as that of the intermediary layer. In another embodiment, the additional and intermediary layers are made of different materials.
It should be understood that the additional layer may comprise more than one layer deposited one on top of the other. The different additional layers may be made of the same material or of different materials.
In one embodiment, the panel 10 is shaped and sized so as to correspond to at least a portion of a shower. For example, the panel 10 may be shaped and sized so as to correspond to a wall, a floor, a ceiling, or the like of a shower.
In another embodiment, the panel 10 is shaped and sized so as to correspond to a bath tub.
At step 54, a layer of acrylic modified isophthalic gelcoat is applied on the mold. In one embodiment, a layer of AcrylX™ is applied on the mold at step 52.
Then, at step 56, a layer of polymer is applied on the layer of acrylic modified isophthalic gelcoat. In one embodiment, the polymer applied at step 56 on the layer of acrylic modified isophthalic gelcoat consists in fiber-reinforced polymer.
Finally, a layer of polyester resin is applied on the layer of polymer at step 58. In one embodiment, the layer of polyester resin consists in a layer of ArmorCore™. Once the different layers are dried, the panel is then formed and can be removed from the mold.
In one embodiment, the method 50 further comprises at least one curing step to dry the layers applied to the mold. For example, a first drying step may be performed after the application of the layer of acrylic modified isophthalic gelcoat on the mold. Once the layer of acrylic modified isophthalic gelcoat is dried, the layer of polymer is applied on the layer of acrylic modified isophthalic gelcoat. A second drying step is then performed in order to dry the layer of polymer. Once the layer of polymer is dried, the layer of polyester resin is applied on the layer of polymer. A final drying step is then performed in order to dry the layer of polyester resin.
It should be understood that any adequate method for applying a layer of material may be used. For example, a layer of material may be applied on the mold or another layer by spraying material. In another example, a roller or a brush may be used for applying a layer of material.
In one embodiment, the top layer 16 has a thickness comprised between about 0.3 mm and about 0.7 mm.
In one embodiment, once being applied to the mold at step 54, the layer of acrylic modified isophthalic gelcoat is cured at a temperature up to 140° F. for a period of time extending between about 15 minutes and about 35 minutes.
In one embodiment, the polyester resin layer 12 has a thickness of about 2.5 mm.
In one embodiment, once being applied on the intermediary layer at step 58, the layer of polyester resin is cured at a temperature up to 140° F. for a period of time extending between about 25 minutes and about 35 minutes.
