Glass bonding technique

In addition to the nature of resin and fibre, the laminate properties also depend on the degree of bonding between the two main components and the presence of other additives including air bubbles. Because of this some parts, fabricated by simple hand building techniques, may exhibit strengths no better or even worse than unreinforced materials. This problem is often worst with glass fibres which are therefore normally treated with special finishes to improve the resin-glass bond. 

Packaging was designed to thermally isolate the device while maintaining electrical and fluid interconnects. The first step was to protect the device from mechanical shock by using spacer chips. Glass-frit bonding techniques were used to bond the chips to the reactor. Low-pressure vacuum packaging and... 

Pyrex glass has been bonded to silicon using an anodic bonding technique. With it, the thermal expansion coefficients of the two materials are similar thus residual stress after bonding is minimized. Operationally, a mirror-polished, clean flat piece of glass is placed on top of a clean... 

An important advantage of ULE (Coming) is the possibility to fabricate lightweight blanks because of the low density of 2.21 g.cm 3 of the glass itself (glass ceramics have values between 2.5 and 2,6 g.cm"3) and because of using special machined and fused core structures and bonding techniques [67]. 

Adhesive properties were monitored both directly and indirectly. Direct measurements included changes in shear strength and Tg (glass transition temperature) of adhesive. Indirect measurements include those changes in mirror properties such as reflectance and shape which may occur as changes occur in the nature of the adhesive bond. Techniques used for the above direct and indirect measurement are summarized below. 

The application of water glass sand as a binder has a low environmental impact, compared to the application of organic binders. This technique allows the (partial) regeneration of the water glass bonded sand and thus reduces the need for used sand disposal and primary raw material...
