Embodiment Construction

[0016] The composite fabric of the present invention comprises layers that are stitched together to form a unitary product. These layers include chopped fiberglass mat, at least one layer of long fiberglass rovings, and a tissue paper backing layer. Composite fabric has many uses, but it is especially useful in the manufacture of composite products made from thermoplastic or thermosetting resins, where the fabric forms a support layer, reinforcement or substrate for the plastic product in a manner known in the art .

[0017] Referring to the drawings, wherein like numerals indicate like parts throughout the several views, there is generally shown a preferred embodiment of the composite fabric 20 of the present invention. The composite fabric 20 includes a number of layers including an upper layer 22 of fiberglass rovings, layers 28, 30, 32 of fiberglass rovings. The composite web 20 also includes a chopped glass fiber strand mat layer 34 and a tissue paper back layer 36 . T...

Abstract

A chopped fiberglass tow mat (34), at least one layer of long fiberglass rovings (22, 28, 30, 32) and a porous tissue paper bottom layer (36) are formed into a multilayer fabric ( 20). A tissue (36) is placed on the first side of the chopped tow mat (34). Layers of rovings (22, 28, 30, 32) are superimposed on one opposing side of the mat (34). The layers are stitchbonded together to form a composite fabric that has favorable resin wetting properties when used as reinforcement in composite products.

Description

technical field [0001] In general, the present invention relates to a composite fabric comprising a chopped glass fiber strand mat. The composite fabric also includes at least one layer of elongated fiberglass rovings and a bottom layer of tissue paper supporting the chopped strand mat. The layers are stitched together to form the composite fabric. [0002] Fabric has various uses such as it can be used as a reinforcing component in molded or composite articles. For example, the fabrics of the invention can be impregnated or impregnated with suitable resins in order to produce poles (such as lamp poles or telecommunication poles), bathroom and toilet fixtures, car and caravan roofs, profiles, bumpers, hoods, Blades (such as windmill blades), skis and snowboards. Background technique [0003] Composite fabrics having layers of glass fiber rovings are well known in the industrial field. For example, glass fibers have a long history of use in the pap...
