Foreword 



This Design Manual has been prepared by Gibbs & Cox, Inc. under the sponsorship of the 

 Owens -Corning Fiberglas Corporation, manufacturers of fiberglass products for the rein- 

 forced-plastics industry, as a part of a program for the advancement of the industry through 

 the dissemination of technical information on the materials and processes presently in use. 

 As a firm of Naval Architects, Gibbs & Cox, Inc. has always been interested in new materials 

 which appear to have application in the Marine Field. Therefore, it was natural that these 

 two organizations combined their efforts to investigate thoroughly this new structural material. 



In the compilation of this manual, it was necessary to acquire additional knowledge about 

 the physical properties of the basic laminates and to determine the types and details of con- 

 struction considered the most satisfactory. This effort required the contributions of many 

 organizations and are acknowledged in the Preface. The results of this testing and study are 

 presented as a Marine Design Manual for guidance in the development of reinforced-plastic 

 structures for marine and other applications.
