CHAPTER 5. ENGINEERING PROPERTIES OF LAMINATES 



Direction properties of cloth and woven roving reinforcements are briefly discussed. 

 Relationships between reinforcements, molding methods, physical and mechanical properties 

 are discussed and tabulated. The basic engineering properties of fiberglass laminates 

 determined from an extensive and supplementary test programs are presented in tabular 

 form. Graphs indicating impact, fatigue and creep properties are given. Factors effecting 

 the engineering properties of laminates are discussed and graphs of the effects of water 

 immersion and long term loading are given. A summary table for the physical and mechani- 

 cal properties of low density core materials is presented. 



CHAPTER 6. DESIGN OF LAMINATES 



The behavior of laminates under load are discussed. Suggested factors of safety for 

 laminates are given. Methods, formulas and approaches to the design of both isotropic and 

 orthotropic laminates in tension, compression and flexure are presented. Laminates as flat 

 rectangular plates under various load conditions are analyzed. Tables of approximate criti- 

 cal buckling loads, and lateral loads are presented. A brief discussion on methods of analy- 

 sis for sandwich construction is given. Detail design examples applying the methods of 

 analysis and design approaches discussed are included as guidance for the designer.
