Vacuum consumables are considered as waste once composite parts are fabricated or prepreg is laid onto the mold. However, Stratview Research considers these materials as "Process Efficiency Enhancers" which play a critical role in achieving the requisite performance of composite parts. Vacuum consumables include vacuum bagging film, release film, peel ply, breather & bleeder, pressure-sensitive tape, sealing tape, vacuum hose, vacuum pump, etc. Vacuum consumables are used during composite parts manufacturing through different processes, such as infusion process, prepreg layup process, filament winding, and wet layup. Vacuum consumables perform a major function of reducing surplus air and resin from the laminate which results in improved performance and reduced VOC emissions. They also optimize the fiber-resin ratio in composite part manufacturing.
The demand for vacuum consumables in the composites industry is highly subjected to the performance of major end markets such as aerospace, wind energy, marine, and automotive. The impact of the COVID-19 pandemic on the demand for vacuum consumables varies from industry to industry. For instance, aerospace & defense emerged to be the biggest victims with demand falling over 30% in 2020. On the other hand, the wind energy industry flourished with a robust growth of mid-teens in 2020, propelled by huge wind turbine installations in China and the USA. Furthermore, the exceptional growth in the wind energy segment has partially offset the decline enumerated in other markets (aerospace & defense, transportation, and marine).
The demand for vacuum consumables in different end markets in 2021 again varied from market to market. Some markets, such as marine and transportation, recorded healthy recovery, whereas wind energy and aerospace, recorded hefty declines. Overall, the composite vacuum consumables market witnessed a mid-single-digit decline in 2021 but is estimated to bounce back swiftly, reaching the market value of US$ 0.8 billion in 2027.
