Abstract
Environmental concerns and cost reduction have encouraged the use of natural fillers as reinforcement in polymer composites. Currently, a wide variety of reinforcement, such as natural fibers and nanocellulose, are used for this purpose. Composite materials with natural fillers have not only met the environmental appeal, but also contribute to developing low-density materials with improved properties. The production of natural fillers is unlimited around the world, and many species are still to be discovered. Their processing is considered beneficial since the natural fillers do not cause corrosion or great wear of the equipment. For these reasons, polymer reinforced with natural fillers has been considered a good alternative for obtaining ecofriendly materials for several applications, including the automotive industry. This review explores the use of natural fillers (natural fibers, cellulose nanocrystals, and nanofibrillated cellulose) as reinforcement in polymer composites for the automotive industry.
Highlights

This review explores the use of natural fillers as reinforcement in polymer composites for the automotive industry
Composites filled with natural fillers have gained great focus and investment by researchers and companies due to the need for renewable, friendly materials with improved properties
Summary
Synthetic materials have played a key role in various industrial sectors of technology such as aerospace, aeronautics, automotive, medical, sensors, computational, etc., [1,2,3,4,5,6]. The development of cleaner processes associated with the interest in environmentally friendly materials has been the focus of research around the world [13,14,15,16,17] In this context, the addition of natural fillers (natural fibers, cellulose nanocrystals, and nanofibrillated cellulose) in the polymers has been a way to prepare ecofriendly composites with improved properties, minimizing the problem in relation to the residue accumulation [18,19,20,21]. We explore the use of natural fibers and nanocellulose as reinforcing fillers in polymer composites in the automotive industry
