Green biodegradable plastics have come into focus as an alternative to restricted plastic products. In this paper, continuous long sisal fiber (SF)/polylactic acid (PLA) premixes were prepared by an extrusion-rolling blending process, and then unidirectional continuous long sisal fiber-reinforced PLA composites (LSFCs) were prepared by compression molding to explore the effect of long fiber on the mechanical properties of sisal fiber-reinforced composites. As a comparison, random short sisal fiber-reinforced PLA composites (SSFCs) were prepared by open milling and molding. The experimental results show that continuous long sisal fiber/PLA premixes could be successfully obtained from this pre-blending process. It was found that the presence of long sisal fibers could greatly improve the tensile strength of LSFC material along the fiber extension direction and slightly increase its tensile elongation. Continuous long fibers in LSFCs could greatly participate in supporting the load applied to the composite material. However, when comparing the mechanical properties of the two composite materials, the poor compatibility between the fiber and the matrix made fiber’s reinforcement effect not well reflected in SSFCs. Similarly, the flexural performance and impact performance of LSFCs had been improved considerably versus SSFCs.

In this work, the wear loss of basalt fiber reinforced polypropylene/polylactic acid polymer composite was analyzed using pin-on-disc under dry sliding conditions. The polypropylene, polylactic acid, and basalt fiber (chopped fiber) are melted and mixed homogeneously using a twin-screw extruder, which is followed by an injection molding technique for specimen preparation. The specimens are named as PPB1 (polypropylene, 50%; polylactic acid, 35%; basalt fiber, 15%), PPB2 (polypropylene, 55%; polylactic acid, 30%; basalt fiber, 15%), and PPB3 (polypropylene, 60%; polylactic acid, 25%; basalt fiber, 15%) based on their weight fraction. The wear rate and coefficient of friction are measured for each sample subjected to three different loads and sliding velocities. It is observed from the wear mapping that the wear loss of sample PPB3 is relatively less when compared with the other samples. The scanning electron microscope images of the worn-out region of the sample reveal the fracture and dislocation of fibers in the matrix. The sample PPB3 shows low wear loss. It is due to the better cohesion between the fiber and the matrixes when compared with the other samples.

In the presented study, the load induced long-term behavior of a biocomposite material is analyzed. The studied material is a unidirectional flax fiber reinforced epoxy resin, material, whose quasi-static mechanical properties can compare with those of glass fiber composites. Samples with a fiber direction of 0� were subjected to two types of multi-level creep-recovery tests, one with a varying creep duration, and the other with a varying creep stress, with the purpose of discriminating the viscoplastic and viscoelastic behavior of the composite. Results show a significant viscous response in time, dependent on both creep duration and creep stress, up to 20% of the elastic one. Sample damage is absent, leading to the conclusion that the viscoplastic response is caused by the permanent reorganization of the fiber�s internal structure.
