The interest on poly(lactic acid) (PLA)/poly(methyl methacrylate) (PMMA) blends has increased during the last years due to their promising properties. The novelty of the current work focuses on the preparation and characterization of biocomposites based on PLA/PMMA matrix and NaOH-treated sisal fibers. The effect of the addition of treated sisal fibers on the physico-mechanical properties of high polylactide content composites was studied. For this purpose, PLA/PMMA blend (80/20 wt%) was prepared by melt-blending and reinforced with different fiber contents. Although composites showed interesting specific tensile properties, the estimated heat deflection temperature (HDT), that is, the maximum temperature at which a polymer system can be used as a rigid material, barely increased 4°C respect to unreinforced system. After the annealing process, the HDT of the unreinforced polymer blend increased around 25°C, whereas the composites showed an increase of at least 38°C. Nonetheless, the specific tensile strength of composite decreased approximately 48% because the adhesion between fiber and polymer matrix was damaged and cracks were formed during annealing process.

Sisal Fibers

Sisal, carbon, and poly-methyl methacrylate (PMMA) are the component materials that have been developed for the biomedical composite. However, characterization of the mechanical properties of the composites affected by some modified treatments is still opened for discussion. Sisal/poly-methyl methacrylate (PMMA) and sisal/carbon/PMMA composites with 30% fiber content and 6 mm fiber length were manufactured using a cold press molding at room temperature for about 60 min curing time. Tensile and bending properties of the composites were investigated by the influence of alkalization, the addition of maleic-anhydride-grafted polypropylene (MAPP) and hybridization of sisal and carbon fibers. The results indicated that the addition of MAPP (3, 5 and 10 wt. %) increases the tensile and flexural strengths of sisal/PMMA composites which are higher than the composites reinforced with alkali-treated and untreated sisal fibers. The addition of 5 % MAPP resulted in more effective improvement in mechanical properties compared to the effect of alkalization. However, a significant enhancement of tensile properties was shown by the hybridization effect of sisal and carbon with a ratio of 1:1 and 1:2 in sisal/carbon/PMMA composites. Scanning electron microscopy (SEM) of tensile fracture surfaces confirmed the presence of a functional relationship between the high mechanical strength of the composites with excellent adhesion between sisal fiber and PMMA by introducing 5% MAPP. Relatively homogeneous fiber dispersion in the matrix either sisal fibers or mixed sisal and carbon fibers within the PMMA matrix with sisal/carbon ratio of 1:2 have also contributed to the improvement of the mechanical strength. The use of alkali-treated sisal and HNO3-treated carbon fibers had promoted a remarkable increase in tensile strength of the sisal/carbon/PMMA hybrid composites.
