AbstractHemp fiber-reinforced green composites with organoclay-filled poly(butylene succinate) (PBS) matrix were fabricated by pultrusion process. Morphological studies revealed that the clay particles were intercalated/partially exfoliated when the clay content was lower than 6 wt%. The tensile modulus and strength of PBS/25% hemp composites were 15 and 2.9 times of the neat PBS. By adding organoclay to the PBS/hemp composites, the tensile properties of the hybrid composites generally reflected the similar change with the organoclay modified PBS matrix. Upon certain duration of environmental exposure, the degradation of tensile properties of hemp/organoclay/PBS hybrid composites was retarded compared with hemp/PBS composites.

Novel hemp fiber reinforced geopolymer composites were fabricated. The matrix was a new geopolymer based on a mixture of red mud and fly ash. Chopped, randomly oriented hemp fibers were used as reinforcement. The mechanical properties of the geopolymer composite, such as diametral tensile (DTS) (or Brazilian tensile) strength and compressive strength (CS), were measured. The geopolymer composites reinforced with 9 vol.% and 3 vol.% hemp fiber yielded average DTS values of 5.5 MPa and average CS values of 40 MPa. Scanning electron microscopy (SEM) studies were carried out to evaluate the microstructure and fracture surfaces of the composites. The results indicated that the addition of hemp fiber is a promising approach to improve the mechanical strength as well as to modify the failure mechanism of the geopolymer, which changed from brittle to “pseudo-ductile”.

Reinforcing Fillers

The use of natural plant fibers as reinforcing fillers in fiber-polymer composites has drawn much interest in recent years. Natural plant fibers as reinforcing fillers have several advantages over inorganic fillers such as glass fibers; they are abundant, readily available, renewable, inexpensive, biodegradable, of low density, and of high specific strength. Hemp fibers are one of the most attractive natural plant fibers for fiber-reinforced composites because of their exceptional specific stiffness. In this review, we summarize recent progress in developments of the hemp fiber reinforced composites such as hemp fiber reinforced unsaturated polyester (UPE), hemp fiber reinforced polypropylene (PP), hemp fiber reinforced epoxy composites, and so on, illustrate with examples how they work, and discuss their intrinsic fundamentals and optimization designs. We are expecting the review to pave the way for developing fiber-polymer composites with higher strength.

Molding Condition

In this study, molding condition and tensile properties of jute fiber reinforced composite were examined. PVA resin was used as matrix which is one of the biodegradable resin. Before tensile test, specimens have an offset twist. The tensile test after twist of jute fiber cloth was also conducted. As a result, following results were obtained. In the case of jute fiber cloth, the effect of twist deformation to tensile strength is not great. The reason is thought that the fiber cloth is flexible and easy to deform in this form. In the case of composite, molding time has an effect to the tensile properties. As the molding temperature increases, the tensile strength increases. So, the diffraction intensity was measured. The reason of effect to the strength is thought that the crystallization occurred in the matrix. When the molding temperature is so high, fiber has degradation, and the strength of the composite decreases. As the degree of twist increases, the strength decreases. The reasons are the delamination between layers and debonding between fiber and matrix.
