Effects of fiber surface treatments

EVOH blend. Results indicated a better wettability of treated coir fibers with matrix as shown in Fig. 10.4. Fiber treatments removed impurities and fatty deposits seen in untreated fibers. Treated fiber composites resulted in mechanical anchorage and reduced pullout and gaps between the fiber and matrix in composite materials. This indicated higher interfacial shear strength for treated fibers and good interfacial adhesion between the fibers and matrix. 

Gomes et al. [23] studied the mechanical properties of cornstarch-based biodegradable resin reinforced with high-strength curaua fibers. Two fabrication methods, preforming and pre-preg sheets, were used in which stretched slivers of curaua fibers were prepared as reinforcement to increase the composite strength. 

Moreover, highty concentrated alkali treatment (10 wt%) was applied to curaua fibers to improve mechanical properties of green composites. Tensile test results showed that alkali-treated liber composites increased in fracture strain twice to three times more than untreated fiber composites, without a considerable decrease in strength. These results showed that highly concentrated alkali treatment is a suitable method for improving fracture strain and toughness of these composites.

Pineapple (Ananas comosus), which is native to Brazil, is a tropical plant with leaves rich in cellulose. Being relatively inexpensive and abundantly available, pineapple fiber may be considered for polymer composite reinforcement. Today, pineapple leaves are a by-product of pineapple cultivation [3]. Devi et al. [43] investigated the dynamic mechanical behavior of pineapple leaf fiber-reinforced polyester composites. Threepopnatkul et al. [44] studied the effects of fiber surface treatments on the performance of pineapple leaf fiber-carbonate composite.

An inspection of the fracture surfaces of composites composed of reinforcing fibers and polymer matrices provides qualitatively useful information on the interfacial adhesion between the fiber and the matrix and also gives rise to an indication of the effect of fiber surface treatment on the mechanical and thermal properties of resulting composites [137-139].
