This application claims priority to and the benefit of provisional patent application number 576/CHE/2014 titled “Fiberglass Laminate”, filed in the Indian Patent Office on Feb. 7, 2014, and non-provisional patent application number 576/CHE/2014 titled “Fiberglass Laminate”, filed in the Indian Patent Office on Feb. 5, 2015. The specifications of the above referenced patent applications are incorporated herein by reference in their entirety.
The invention disclosed herein, in general, relates to composites. More particularly, the invention disclosed herein relates to a pinstripe decorative fiberglass laminate.
Currently available decorative laminates such as high pressure laminates and low pressure laminates do not provide sufficient color richness. The color quality is limited by the presence of print on a cellulosic paper. Moreover, the cellulosic content in a high pressure laminate makes it unsuitable for highly fire resistant applications such as surfacing applications in the aerospace industry.
Conventional methods use a decorative cellulosic paper on a fire resistant glass fiber paper for creating a decorative laminate. However, the aesthetics of these solutions are restricted by color quality constraints of the decorative cellulosic paper. Directly coloring a fiberglass woven mat or a non-woven glass chopped fiber surface mat of low weight, for example, of about 30 grams per square meter (gsm) does not provide color sharpness and image clarity. The color clarity and resolution of the print in these solutions are insufficient for high clarity pinstripe designs.
Hence, there is an unmet need for a pinstripe decorative laminate that provides straight line color sharpness, color quality, and high fire resistance.
This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter.
The fiberglass laminate disclosed herein addresses the above mentioned need for color sharpness of a pinstriped effect and high fire retardancy. The pinstripe decorative fiberglass laminate disclosed herein comprises colored unidirectional zero twist glass fiber rovings. Pigmented unidirectional zero twist glass fiber rovings provide a pinstriped effect with substantial color richness and aesthetic quality. The colored straight lined zero twist glass fiber rovings provide substantial straight line color clarity. The untwisted transparent colored fibers create a substantial color effect.
For light colored pinstripes, colored zero twist unidirectional glass fiber rovings are impregnated with a melamine resin and cured to form the fire resistant, pinstripe decorative fiberglass laminate. For dark colored pin stripes, colored zero twist unidirectional glass fiber rovings are impregnated with a phenolic resin and cured to form the fire resistant, pinstripe decorative fiberglass laminate.
As typical direct rovings with twist do not provide sharp pinstripe patterns, zero twist rovings are required. Furthermore, color sharpness of colored zero twist unidirectional glass fiber rovings is substantial when compared to color sharpness obtained by directly coloring a fiberglass woven mat or a non-woven glass chopped fiber surface mat of low weight, for example, of about 30 grams per square meter (gsm).
The foregoing summary, as well as the following detailed description of the invention, is better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, exemplary constructions of the invention are shown in the drawings. However, the invention is not limited to the specific methods and structures disclosed herein. The description of a method step or a structure referenced by a numeral in a drawing is applicable to the description of that method step or structure shown by that same numeral in any subsequent drawing herein.
For light colored pinstripes, colored unidirectional glass fiber rovings are impregnated with a melamine resin and cured to form the fire resistant, pinstripe decorative fiberglass laminate 101. For dark colored pin stripes, colored unidirectional glass fiber rovings are impregnated with a phenolic resin and cured to form the fire resistant, pinstripe decorative fiberglass laminate 101.
The foregoing examples have been provided merely for the purpose of explanation and are in no way to be construed as limiting of the present invention disclosed herein. While the invention has been described with reference to various embodiments, it is understood that the words, which have been used herein, are words of description and illustration, rather than words of limitation. Further, although the invention has been described herein with reference to particular means, materials, and embodiments, the invention is not intended to be limited to the particulars disclosed herein; rather, the invention extends to all functionally equivalent structures, methods and uses, such as are within the scope of the appended claims. Those skilled in the art, having the benefit of the teachings of this specification, may effect numerous modifications thereto and changes may be made without departing from the scope and spirit of the invention in its aspects.
