Fiberglass, a material that has stood the test of time, has a fascinating history dating back centuries. The roots of its innovation can be traced to Prussian inventor Hermann, but it was in 1936 when du Pont combined glass fibers with plastic, birthing a revolutionary composite material. This marked the genesis of what we now know as fiberglass, a key player in the realm of structural and building materials.
The advent of polyester resins in 1942 by Cyanamid paved the way for the development of modern fiberglass. The marriage of fiberglass and resin replaced the gas content in the material with plastic, endowing it with unparalleled strength. Though insulation properties were compromised, the composite showcased remarkable structural promise, earning its place in the construction industry.
The term “fiberglass” stuck, and its evolution continued. Unlike glass fibers utilized for insulation, the success of fiberglass in structural applications hinges on the meticulous elimination of defects from the fiber surfaces. This defect-free state ensures gigapascal tensile strengths, a prerequisite for the material’s structural integrity.
The manufacturing process, known as pultrusion, involves melting silica sand, limestone, and various minerals in large furnaces until a liquid forms. The resulting mixture is extruded through bushings to form the foundational structure of fiberglass.
Coating or priming the roving becomes imperative, serving a dual purpose:
Protecting the glass filaments: This safeguards the fibers during processing and manipulation.
Ensuring proper bonding: The coating fosters a strong bond with the resin matrix, facilitating the transfer of shear loads from the glass fibers to the thermoset plastic. This bond prevents localized failures caused by fiber slippage in the matrix.
E-glass, an alumino-borosilicate glass with minimal alkali oxides, reigns supreme as the most common type of glass fiber in fiberglass. Primarily employed in glass-reinforced plastics, E-glass is a game-changer in the composite material landscape.
