A non-woven matrix of glass fibers, synthetic and natural fibers provides a rigid but resilient product having good strength and insulating characteristics. The product may be utilized in a planar configuration or be further formed into complexly curved and shaped configurations. The matrix consists of glass fibers, synthetic fibers such as polyester, nylon or Kevlar and natural fibers of wood or textiles which have been intimately combined with a thermosetting resin into a homogeneous mixture. This mixture is dispersed to form a blanket. A variety of products having varying thickness and rigidity may then 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. An alternate embodiment includes a conductive/coloring agent such as carbon black.
