REINFORCED PLASTIC MAGNETIC TAPE.
Abstract
The objective of this project is to determine the feasibility of developing complete tapes which will improve the efficiency and reliability of automatic data processing equipment and astro electronic recording devices. During the first quarter, significant improvement was achieved in the tear and cre1se resistance of the Lexan(R) impregnated glass cloth tape base developed during the first year. This was achieved by: (1) Imparting a 30 to 45 degree bias across the reinforcing web. (2) Applying Elvax primer coat and Lexan(R) impregnant to the glass cloth with out first removing the starch-oil sizing. (3) Using the special hot pressing technique to achieve homogeneity and smoothness. Improved surface quality of the composite base is a fur ther benefit of the biased fabric. Magnetic iron oxide coating studies were started during this quarter. Equipment design was completed and much of the fabrication done for a continuous pilot plant capable of producing 4-1/2 inch wide tape base at a rate of 20 feet per minute. (Author)
