ABSTRACT:
A non-woven matrix of glass and synthetic fibers provides a rigid but resilient product having good strength and insulating characteristics. The matrix consists of glass fibers and synthetic fibers such as polyester, nylon or Kevlar which have been shredded and intimately combined with a thermosetting resin into a homogeneous mixture. A conductive material in either particulate or fibrous form is added to improve surface finish and, if desired and depending upon the choice of conductive material, darken the appearance of the product. This mixture is dispersed to form a blanket. The product may be utilized in a planar configuration or be further formed into complexely curved and shaped configurations. A variety of products having varying thickness and rigidity may be produced by controlling the compressed thickness and the degree of activation of the thermosetting resin. The product may also include a skin or film on one or both faces thereof.
