What is the Building Block approach, and why is it used? What are the purposes of a structural test program? -Establish failure modes -demonstrate compliance with criteria -correlate test result with predictions -assure service life performance What are some moisture absorption effects for composite materials and what factors govern these effects? -moisture absorption a diffusion process -plasticizer response -decrease matrix Tg -decrease primarily in matrix dominated and interface properties -knockdown a function of property Factors: -matrix -fiber type -time -geometry -temperature -relative humidity -exposure conditions What are the types of specifications and what are they each used for?
