Siefert - Granville With reference to your memo dated September 19 1961 we should have a lot of data for the November 6th Business Outlook Meeting For your October 4th interim meeting we have the following to report 1 We are working in cooperation with Glass Research on the evaluation of new glass compositions as reinforcement for Kaylo Four glasses have been given preliminary screening to date Only one warrants further evaluation A high glass identified as 815 will be fully tested in Kaylo since it did hold up to some degree in the preliminary test Glasses identified as X- 57E high alumina and high magnesia 934 high alumina and a chrome treated refrasil would not withstand autoclaving In view of our initial success with coated E glass fibers I question whether we would want to go to these more exotic glasses which are costly and difficult to form 2 3 Our work with coated E glass fibers has been limited to just two coatings asphalt warp yarns from ) and vinyl chloride coated Fiberglas screening base stock Both of these coated fibers withstand autoclaving sufficiently to warrant their possible use in Kaylo The problem with coated glass yarns is coating the fact that once the organic in the autoclave the fiber remains deteriorates or melts away in a void of larger diameter than the fiber itself Consequently there is no bond whatsoever remaining between Kaylo and the fiber Our program for the next month involves application of various organic or organic- inorganic coatings which should have a better chance of standing up to autoclaving conditions We must somehow maintain the bond between Kaylo and glass fibers A possible method of tying the glass to the Kaylo would be the use of the " wire concept We plan to apply a coating to the yarns which form warts on the surface One possible method would be to dust the resin coated yarns with fine sand just least mechanized hinging before cure This would give us at By nature I like to immediately rule out pan of Kaylo try things Yesterday we which most people added excelsior to a would small Mr. B. E. Boyd - Toledo Page 2 September 22 1961 Surprisingly it held up fairly well in the autoclave Sine the sample was too small for formal testing I threw the sample as high as I could above a concrete floor To my surprise the sample only cracked it did not break In fact it did not break even after a second toss into the air autoclaving This breaks any bond Excelsior shrinks during which might have existed between Kaylo and the fiber surface Excelsior impregnated with some materials which prevents shrinking might work We plan to follow up this idea even though it does not involve glass fiber Our work during October will involved evaluation of 1 Textile and wool waste including bushing drippings 2 Organic and inorganic coated glass fibers 3 Experimental glasses submitted by Glass Research There is some confusion amount various people in our company as to our objective in the reinforcement of Kaylo with glass fibers With the possible exception of textile and wool waste we do not plan to add any more glass than is necessary to achieve the result we are seeking We do not plan to substitute glass pound for pound for asbestos asbestos 4-10 cents per lb. - glass 40 cents and up We will use it in addition to the asbestos probably in the range of 2-5 by weight Of course we might replace some of the short asbestos with textile and wool waste Unless the glass waste improves physical properties I would prefer to increase the amount of Kaylo dust which we also have great quantities to control viscosity etc of the Kaylo batch R.
