“…Aspect ratio and particle size proved to influence properties considerably and contrary to many claims published in the literature [15,[33][34][35][36][37][38][39][40][41] we found that interfacial adhesion is rather strong between PLA and lignocellulosic fibers. As a consequence, usually the fracture of the fibers is 4 the dominating micromechanical deformation process, which determines composite strength.…”

“…This result indicated that the EFB pulp fibers had an effective interaction with the seaweed matrix. As both materials were hydrophilic, they were able to form hydrogen bonds between each other (Bax and Müssig 2008). Subsequently, strong adhesion interaction formed between both components with better wetting of the pulp fiber by the seaweed matrix.…”

“…Only weak bonds are formed between them, such as Van de Waals forces or mechanical anchoring induced by compressive residual stress. Thus, agglomeration of fibers often occurs in the polymer matrix, which eventually deteriorates the strength of the composite (Bax and Müssig 2008;Širvaitiene et al 2013).…”

Cellulosic Pulp Fiber as Reinforcement Materials in Seaweed-Based Film

Composite materials made from renewable resources can minimize the environmental pollution. In this work, biocomposite films were produced using seaweed as matrix and empty fruit bunch (EFB) pulp fibers as reinforcement. Based on the results, the EFB pulp-seaweed composite films exhibited better mechanical properties than the seaweed film. It was also observed that 50% EFB pulp loading gave the highest tensile strength (81.4 MPa) and elongation at break (5.4%). This phenomenon was supported by SEM analysis, in which more fiber breakage than fiber pull-out was observed on the tensile fracture surface of composite film. Additionally, no agglomeration of the pulp fibers was observed. Instead, the pulp fibers were homogenously distributed throughout the film. In contrast, the contact angle of the seaweed-based films started to decrease once the pulp fibers were added. The decrease in the contact angle was attributed to the hydrophilic nature of the pulp fibers. Nevertheless, the contact angle values of all composite films were still comparatively high and thus, this would not affect their application as a packaging film.

“…Bax and Müssig (Bax and Müssig, 2008;Hughes et al, 2007) used SEM to characterise the failure mechanisms of natural composites. As discussed previously, composites B, C and D showed delamination behaviour without fracture during tensile testing.…”

Flax reinforced tannin-based composites have a potential to be used in vehicle applications due to the environmental advantages and good mechanical properties. In this paper, the effects of fibre configuration on mechanical properties of flax/tannin composites were investigated for nonwoven and woven fabric lay-up angles (UD, [0°, 90°] 2 and [0°, +45°, 90°, -45°] 2 ). The tannin/flax composites were prepared by compression moulding. The manufactured specimens were then characterized for quasi-static tensile properties, dynamic mechanical properties and low-energy impact performance. Failure mechanism was further investigated using microscopy and demonstrated the need for further adhesion improvements.The study shows that the UD fabric reinforced composite performs better in tensile strength and modulus whereas [0°, +45°, 90°, -45°] 2 composite provides the best impact energy absorption performance.
