RESEARCH, DEVELOPMENT, AND FABRICATION OF SILOXANE-ACRYLATE INTERLAYER MATERIAL
Abstract
The object of this research, development, and fabrication program was for the production of interlayer sheet material. This interlayer material consisting of a copolymer of 99 part of ethyl acrylate and one part of vinyl polysiloxane was developed under Air Force Conract 33(600)-22723 and is described in WADC TR 54-57. This developmental work was undertaken between 15 June 1954 and 15 June 1955. Attempts to mill and calender the interlayer material were unsuccessful. This necessitated the production of interlayer sheets by casting between glass plates. Thermal polymerization was substituted for ultraviolet polymerization for quality production purposes. Sheets produced by this method, however, were optically imperfect. An adhesive as required for laminating the interlayer sheet to glass or plastic. Residual traces of the parting agent, however, prevented good lamination. Seven 0.200 inch by 37 inch interlayer sheets varying in quality were submitted. Recommendations are given for methods of improving the optical quality of future interlayer sheets. (Author-PL).
