Abstract

<PICT:0848260/IV(a)/1> <PICT:0848260/IV(a)/2> A cellular polyurethane structure with glass elements uniformly distributed throughout the structure is characterised in that the glass elements have a thickness less than 150 ten-thousandths of an inch and a length and width greater than 1/64 inch with a substantial amount of the glass elements encompassed within the cell walls, said cellular structure having increased strength, rigidity and improved compressive characteristics by comparison with a cellular plastic of the same composition without the glass elements. It also comprises such a polyurethane structure in which the glass elements are in the form of glass fibres having a diameter less than 150 ten-thousandths of an inch and lengths within the range of 1/64 to 1/4 inch, or in the form of a fabric. Such structures can be prepared by foaming and curing the polyurethane with the glass elements distributed therein. When the glass elements are in the form of a fabric, one or more fabrics are introduced into a confined space, the polyurethane foaming constituents are introduced into the space in amounts sufficient to fill the space on cellulation and the polyurethane is foamed while being advanced to a set stage whereby the resin penetrates through and fills the interstices of the textile fabric of glass fibres substantially completely to encompass the fabric within the cellulated plastic. The glass may have a preliminary treatment with dextrinised starch and incompatible oil, unsaturated organosilicon compounds such as vinyl trichlorosilane, unsaturated Werner compounds, such as methacrylate chromic chloride, polyvinyl alcohol, polyacrylic acids, gelatine and other proteins, polyacrylamides and ethylene diamine polymers. In examples (1) glass fibres of 35 ten-thousandths of an inch in diameter and length 1/8 to 1/32 inch, sized with dextrinised starch and oil, are damped with water, mixed with a polyester-di-isocyanate liquid mixture in a confined space and heated at 250 DEG -300 DEG F to give a body 12 (Fig. 1) containing voids 10 and fibres 14 and 16 ; (3) glass fibres in the form of a fabric 20 (Fig. 2) have a resin foamed in the space which they occupy to embed the fabric within the body 22 of the foamed plastic. The glass fibres can be used in the form of mats or packs, which are wetted with the resin which is then foamed. Structural panels are thereby formed.
