Description
RELATED APPLICATIONS
[0001] This application is a continuation of application Ser. No.
10/992,606, filed Nov. 18, 2004, which is a continuation of
application Ser. No. 10/081,629, filed Feb. 20, 2002, both of which
are incorporated by reference herein in their entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates generally to construction
materials and more particularly to a reinforced composite material
that includes a laminated material of the type called high pressure
laminates ("HPL") and a strengthening panel such as fiberglass
reinforced plastic ("FRP") adhered together, and to the manufacture
of such a composite material.
[0004] 2. Description of Related Art
[0005] High pressure laminate materials have been manufactured and
sold for many years, and are familiar to many from their
wide-spread use in kitchens and areas requiring very durable and
decorative surface attributes. Such laminates are typically made of
layers of paper impregnated with resin, compressed and heated to
produce the desired laminate. One layer of paper may have a
decorative pattern that remains visible in the finished product.
The exact types of paper and of resins used, as well as the
pressures and temperatures, and the precise order of steps, are
well known to those in the art. A great variety of products of this
type are commercially available from the Formica Corporation, under
the trademark Formica, owned by that company.
[0006] HPL products, however, are generally brittle enough that
they must be mounted on a layer of wood or other material of
sufficient strength and rigidity, for use in the kitchen, and on
any horizontal surface. Vertical surface applications of HPLs would
be enhanced by a pre-laminated panel with the HPL as the outward
side. A primary application of the proposed panel would be vertical
wall surfaces, where drywall is a common substrate.
[0007] It would be desirable to be able to use HPL products in
environments where the product will be exposed to relatively high
levels of wear and tear, moisture, and mechanical loads, without
the need to mount the HPL on a mechanically strong layer of wood or
other materials. For example, it would be desirable to be able to
use decorative materials like HPL products in schools, hospitals,
restaurants and other public areas that are subject to large
amounts of traffic, and where conventional HPL cannot easily be
used.
[0008] Also known are sheets of plastic reinforced with fiberglass,
which have long been employed as surfaces that are resistant to
abuse (that is, resistant to tearing and the like), and resistant
to moisture as well. Such products are obtainable commercially, for
example, from Kemlite Corporation, the assignee of the present
invention. FRP products thus far typically have an embossed
surface, are a solid color (typically white), and have a hard and
shiny appearance that makes them unsuitable for uses where esthetic
appearance is of great concern.
SUMMARY OF THE INVENTION
[0009] Accordingly, one object of the present invention is to
provide a material that will have the aesthetic qualities of HPL
and can be easily installed on vertical surfaces. It is also an
object to provide such a material that will have sufficient
mechanical strength for use in situations where conventional HPL
products might not otherwise be usable, such as wall panel
applications without a substantial structural substrate. Of primary
importance, the present invention provides a panel which is
installer-friendly and combines the custom color/pattern
flexibility of an HPL face with a water-proof, dimensionally
stable, user-friendly backer. Further, this laminated panel
enhances the impact resistance and moisture resistance of known
available decorative vertical wall panels. The subject panel will
allow installation of an HPL vertical surface in a most expeditious
manner saving labor costs in two ways: drywall preparation, and
actual installation time of the panel, when compared to applying
HPL directly over drywall.
[0010] These objects are met by the present invention, according to
one aspect of which is a reinforced composite material that
includes a laminate panel, a strengthening panel that includes a
reinforcement embedded therein, and a layer of adhesive disposed
between the laminate panel and the strengthening panel to adhere
the laminate panel and the strengthening panel together.
Preferably, the reinforcement in the strengthening panel may be
fiberglass fibers, randomly oriented, or it may be provided in the
form of a mesh or the like. In either case, the strengthening panel
is preferably a plastic (polymeric) material of the type known as
fiberglass reinforced polyester.
[0011] The invention also provides a method for the production of
such a material, in which there are provided a laminate panel of a
type made by heating and compressing at least a first layer of
paper and quantity of resin, and a strengthening panel of a type
made by embedding a reinforcement in a layer of a binder material.
Then, the laminate panel is adhered to the strengthening panel with
a layer of adhesive. The adhesive may preferably be a hot melt
adhesive.
[0012] These and other objects, features and advantages of the
preset invention will be more fully apparent from a consideration
of the following detailed description of the preferred embodiments,
taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] FIG. 1 is a view of a preferred embodiment of a composite
material according to the present invention.
[0014] FIGS. 2a and 2b are details showing two varieties of FRP
that may be used in the embodiment shown in FIG. 1.
[0015] FIG. 3 is a chart illustrating a method of manufacturing a
material according to the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] The first preferred embodiment of the present invention is a
reinforced composite material having three layers, as shown in FIG.
1. Two outer layers sandwich, and are secured together by, a third
layer, of adhesive. One of the outer layers is a HPL material, and
the other of the outer layers is a sheet or panel of a reinforced
material. The intermediate layer is of an adhesive material. The
reinforced material may be a FRP material of a type available from
Kemlite Corporation, while the other outer layer is for example of
a type available from the Formica Corporation. The exact choice of
adhesive is not critical, and it is believed that many commercially
available adhesives are suitable for adhering combinations of HPL
and FRP materials in this fashion. The present inventor
particularly contemplates, however, the use of a conventional
hot-melt adhesive, a great number of which are known in the art,
and detailed description of which is therefore not required.
Nonetheless, the key quality of the adhesive used is not that it be
a hot-melt adhesive, nor that it be any other particular kind, but
that it provide the bonding qualities necessary to bond securely
with the particular HPL and FRP materials used in a given instance.
The selection of the right adhesive for a particular choice of the
outer layers, thus, is well within the ordinary skill in the
art.
[0017] While it is preferred to use a sheet of FRP material for the
reinforcing sheet, it is also possible to use other types of
reinforced plastic. For example, a plastic sheet having reinforcing
material in the form of a mesh, rather than in the form of
randomly-oriented fiberglass, as in FRP, forms a second preferred
embodiment of the invention. FIGS. 2a and 2b indicate these two
types of material for use in the composite material shown in FIG.
1.
[0018] The method of manufacturing the composite material shown in
FIG. 1 is straightforward, and is illustrated in FIG. 3. First, one
selects the appropriate HPL and reinforced plastic materials to use
as the outer layers. While these materials may be custom
manufactured, either or both may be a commercially available
material instead. Once these two materials have been formed, or
otherwise provided, the appropriate materials and techniques for
adhering the two layers to each other can be selected and used.
[0019] While the present invention has been described in detail
with reference to the currently-preferred embodiments, many
modifications and variations of those embodiments will now be
apparent to those skilled in the art. Accordingly, the scope of the
invention is not to be limited by the details of the foregoing
detailed description, but only by the terms of the appended
claims.
