Preface 



The rapid expansion of the application of fiberglass reinforced-plastic laminates as a 

 structural material in many fields has surpassed the accumulation of the necessary technical 

 data and design information such as is available for the application of other established 

 structural materials. 



Within the relatively short period since the introduction of fiberglass reinforced-plastic 

 laminates, a considerable amount of research effort has been expended by government and 

 industry to determine the potential value and limitations of this new material. However, 

 most of the effort has been spent in developing data for specific applications. As a result, 

 little well controlled data has been made available to organizations, designers and fabrica- 

 tors. The necessity for a large scale program for evaluating the basic engineering properties 

 of fiberglass material has long been recognized. The influence of geometry, laminate con- 

 struction, molding methods and fabrication techniques on these basic properties is ex- 

 tremely important. 



To develop this required engineering data, Owens-Corning Fiberglas Corporation spon- 

 sored a cooperative program which included the following participating organizations:
