Properties of glass fibers for polypropylene reinforcement

Continuous glass fibers were first manufactured in substantial quantities by Owens-Corning in the 1930s for high-temperature electrical apphca-tions. The raw materials are blended, in the proportions shown in Table 1, to form a glass batch which is melted in a furnace and refined during 

Several types of silicate glass fibers are manufactured for the textile and composite industry. Their chemical compositions described below from ASTM C 162 were developed to provide combinations of fiber properties directed at specific end-use apphcations  

A-glass Soda lime silicate glasses used where the strength, durability, and good electrical resistivity of E-glass are not required  

C-glass Calcium borosilicate glasses used in corrosive acid environments  

D-glass Borosilicate glasses with low dielectric constant for electrical applications
