Page 251 - Surface Preparation1 Surface preparation of a material prior to bonding is the keystone upon which the adhesive bond is formed . Extensive field service experience with structural adhesive bonds has repeatedly demonstrated that adhesive durability and longevity depends on the stability and bondability of the adherend surface.

Page 200 - ... properties can also influence final laminate quality. Prepreg tack is one such property. Prepreg tack is a measure of the stickiness or self-adhesive nature of the prepreg plies. Many times, prepregs with a high tack level have resulted in laminates with severe voids and porosity. This could be due to the potential difficulty of removing entrapped air pockets during collation with tacky prepreg. Again, moisture can be a factor. Prepregs with a high moisture content have been found to be inherently...
Page 224 - Chemical composition and processing of epoxy resin systems are known to affect the flow behavior and reaction kinetics of carbon/epoxy prepregs. A study was conducted to assess the influence of catalyst content, resin mixing and advancement, and prepreg resin content on the properties of both neat resin and prepreg. Testing included physical, chemical, thermal, and viscosity characterizations. Next, carbon/epoxy laminates were fabricated and evaluated to determine the impact of both prepreg variations...
Page 243 - Bonded joints enable the design of smooth external surfaces and integrally sealed joints with minimum sensitivity to fatigue crack propagation. Dissimilar materials can be assembled with adhesive bonding and the joints are electrically insulating, which prevents galvanic corrosion of metal adherends.
Page 78 - Cyanate ester resins are bisphenol derivatives containing the ring forming cyanate functional group. Chemically, this family of thermosetting resins are esters of bisphenols and cyanic acid which cyclotrimerize to substituted triazine rings upon heating (Ref. 1).
