Increasing Product Demand from Transportation Industry to Drive Market Growth

Glass fibers have been utilized in the transportation sector as reinforcement since mass-produced pultrusion approaches were first documented. A matrix of liquid resin was combined with continuous reinforcement fabric strands to enhance the material's structural integrity, further enabling the glass wool to be formed into high-strength structural shapes. This material offers a superior strength-to-weight ratio for the transport sector, thanks to its improved resistance to many corrosive media.

For transport applications, this material is ideal as it is lightweight, solid, rigid, offers excellent protection from external elements, can be shaped into any size & form, and has an excellent finish. It is used in the automobile and wind energy industries owing to its low weight, high strength-to-weight ratio, and excellent longevity.

Moreover, structural reinforcements and crash protection systems are now increasingly being manufactured using reinforced polymer materials. For instance, Chrysler, a vehicle brand owned by Stellantis, has been using fiberglass products to build a supporting beam for a blow-molded plastic fuel tank owing to the material’s advanced thermal properties and corrosion resistance.

Due to the need for impact-resistant and lightweight materials, the marine and automotive sectors are using fiberglass on a large scale. To reduce carbon dioxide emissions, stringent regulations have been imposed on the automotive industry. It has encouraged the sector to introduce lightweight, fuel-efficient vehicles to reduce greenhouse gas emissions. This composite material is also widely used as a substitute for aluminum and steel in the automotive industry to produce lightweight cars. This is expected to drive market growth during the forecast period.

MARKET RESTRAINTS

Emission of Harmful Substances into Environment May Obstruct Market Growth

Fiberglass processing consumes substantial energy and resources. For each kilogram of molten glass, 1 kg of carbon dioxide (CO2) is released into the environment, in addition to nitrogen oxide (NOx), sulfur dioxide (SO2), chlorine, fluoride, Volatile Organic Compounds (VOCs), and particles.

In comparison, for every ton of molten glass, 17 GJ of electricity is consumed. Some 25% of this fiber is sent to landfills at the end of its life, amounting to around 250,000 tons/year in Europe. This results in a significant emission of harmful substances into the environment and a decrease in landfill space. Due to its characteristics, Glass Fiber Reinforced Polymer (GFRP) is widely accepted. It is neither fusible nor soluble due to the polymeric portion's thermoset nature, thereby preventing direct remelting or remolding. These fabrics typically contain a significant quantity of inorganic fillers in addition to glass and polymeric matrix, so they are difficult to recycle. GFRPs are typically sent to landfills or incinerators, where they have a detrimental environmental impact.

Thus, for the sustainable growth of the industry, the development of proper recycling technologies for glass wool and other composite materials is becoming crucial.
