Abstract
AbstractApplications of carbon fiber reinforced epoxy-based composites have been highly restricted due to their high cost in the manufacturing process. Cellulose, a cheap and abundant material from nature, shows excellent mechanical property and structural stability. It shows huge potentials in substituting carbon fiber/epoxy with cellulose/epoxy composites to fulfill the great demands for composites with good performance and a reasonable price. This paper first reviews works about the preparation and regulation of cellulose materials based on the very basic concepts of top-down and bottom-up. Then research about the interfacial regulation between cellulose and epoxy has been discussed in two broad classes of covalent and non-covalent modification. Finally, the enhancement effect of cellulose reinforcement has been discussed in two broad classes of dispersive reinforcement and continuous phase reinforcement. The latter can be further divided into three classes according to the dimension feature (1D, 2D, and 3D). The results show that the nanolization of cellulose is necessary for guaranteeing the strength of composites, while the formation of macroscopic and continuous structures can ensure Young’s modulus of composites.
Highlights
Composites play an important role in modern society in meeting the increasing demand for structural materials nowadays
We believe that cellulose/ epoxy composites can be of viable substitution to carbon fiber reinforced polymer (CFRP) in fulfilling the large demand in various applications of the low to mid-range, which exhibit lower requirements for composites
It is worth noting that the crystal structure [69], as well as the intermolecular interactions [70], of regenerated cellulose materials has changed during the regeneration process
Summary
Composites play an important role in modern society in meeting the increasing demand for structural materials nowadays. Served as the typical composite materials with excellent performance, carbon fiber reinforced polymer (CFRP) has been widely applied in various fields. Cellulose materials can meet the rigorous requests of serving as the reinforcing component of the composite. We believe that cellulose/ epoxy composites can be of viable substitution to CFRP in fulfilling the large demand in various applications of the low to mid-range, which exhibit lower requirements for composites. Natural fiber composites can be applied in the fields of building materials (e.g., highly transparent composites in substitution of glass), automotive (advantages in the specific strength and cost) [7], and so on
