Mechanical Properties of Abaca Fiber Reinforced Urea Formaldehyde Composites

Abstract

The present investigation focuses on the fabrication and mechanical characterization of alkali treated natural abaca fiber reinforced urea formaldehyde composites. The composites were prepared by means of compression moulding, and then the effects of fiber loading on mechanical properties such as tensile strength, flexural strength and impact strength were investigated. The composite with 40 wt% abaca fibers gave excellent tensile strength and flexural strength showing that it has the most superior bonding and adhesion of all the composites. In particular, the highest value, 10.02 kJ/m2 of charpy impact strength is observed in the composite with 50 wt% abaca fiber. This work revealed the potential of using abaca fibers in fiberboard.

Effects of Musa textilis fiber loadings in physical-mechanical properties of recycled thermoplastic compounds

“…A somewhat remarkable aspect was the increment of mechanical properties (Fig. 2); the ber loading increased the bending of biomaterial, agreeing with previous studies of Bledzki et al 24 and Suvara et al 13 . However, our results showed that ber loading of 10 and 20% showed the lowest values in MOE f and E f ; this answer is due to the high stickiness of the recycled thermoplastic 2 , and the polarity of the ber could reduce the dispersion of the ber in the matrix (e.g., ber clusters), strongly affecting the resistance of the biomaterial and the generation of free spaces (Fig.…”

“…Our composite materials met these standards due to the high mechanical resistance of the M. textilis ber 12 . Generally, The properties of the composite material and its potential for use depend on the physical-mechanical properties of the natural ber 4,22 , ber loading in the matrix 9 , degree of cohesion between ber-thermoplastic 1 , and adaptability of the materials to the extrusion method used 13 .…”

“…Usually, recycled thermoplastics have poor mechanical resistance and are susceptible to organic and polar solvents, limiting their use in industrial sectors and reducing market use 10 ; thus, developing composite materials in which natural bers are an attractive option 11 . Natural ber is a renewable raw material, easy to produce, with low environmental impact, and abundant on the planet 12,13 . Additionally to the wide variability of types of bers with different physical-mechanical properties, they allow the development of different matrices with properties according to industries with high-quality demands, such as aeronautics, automotive, electronics, and textiles 6 .…”

Study on influence of fiber length and fiber weight proportion in mechanical behavior of Calotropis gigantea fiber‐epoxy composites

“…The test results of CG fiber‐epoxy composites reveal that, it is a potential reinforcement material for polymer composites. This is also validated by comparing the test results with the previous research works on thermoset polymer composites made from some natural fibers, like Abaca, [ 32,11 ] Bamboo, [ 33,34 ] Banana, [ 35 ] Coconut sheath, [ 36 ] Coir, [ 37 ] Hemp, [ 38 ] Zea, [ 39 ] Jute, [ 40 ] Kenaf, [41,42] and Pineapple. [43] Most of these selected composites were prepared by same processing conditions, which enables comparison between them.…”

A Review of Abaca Fiber-Reinforced Polymer Composites: Different Modes of Preparation and Their Applications

“…44 Other treatments reported include the use of benzene diazonium salt, 45 enzymes, 46 and sodium hydroxide 47 with noticeable improvement in mechanical properties as long as properly optimized. Abaca has also been used in conjunction with furan resin, 48 epoxy resin, 49 urea formaldehyde, 50 polylactic acid 51 and high impact polystyrene 52 with moderate success. Plasma treatment of abaca fabric enhanced its adhesion to unsaturated polyester and improved its wettability but exhibited notable low tensile strength even with supplementary mercerization and silylation.…”
