Sufficient development of the necessary technical information and data has been completed 

 to justify the compilation of this Design Manual. This development consisted of the evaluating 

 of the data from an extensive test program to establish necessary physical properties for 

 fiberglass mat, woven roving and cloth reinforced laminates molded by the contact molding 

 method. The use of this data and suggested methods of analyses are demonstrated in the 

 design examples, as a guide for designers and fabricators. 



Throughout this entire program, complete cooperation was maintained by all participating 

 organizations as well as other interested organizations providing information and assistance. 



Gibbs & Cox, Inc. fully realizing that only partial completion of this tremendous task has 

 been accomplished, sincerely wishes to thank the Owens- Corning Fiberglas Corporation, the 

 sponsor, and all the other contributing organizations as well as all the individuals, who worked 

 on and/or assisted in this program for their excellent cooperation. 



In addition to the test program referred to above, considerable information was obtained 

 from an extensive list of available references. Gibbs & Cox, Inc. wishes to acknowledge 

 these fine references which were of considerable importance in the development of this manual.
