“…Subsequently, strong adhesion interaction formed between both components with better wetting of the pulp fiber by the seaweed matrix. According to Coutinho et al (1997), good wetting is essential for the establishment of strong interfacial adhesion. Thus, the pulp fibers supported stress transfer from the seaweed matrix to obtain optimum strength properties of the composite.…”

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.

“…Incorporation of wood flour in PP matrix significantly increased strength and modulus of composites. The increase in tensile strength or modulus is primarily attributed to the presence of fiber, which allowed a uniform stress distribution from continuous PP matrix to dispersed fiber phase (Coutinho et al, 1997).…”

The weathering effect in natural environment on kenaf blast and unsaturated polyester composite Abstract.A Kenaf composite was prepared by using hand lay-up process. The effect of weather on mechanical, morphology and thermal properties of kenaf composite were studied. Tensile strength of kenaf compositewas found to be 60MPa. Unfortunately, tensile strength of thecomposite starts to decrease after the first weathering month through to the weathering periods with constant reduction of tensile, at the end of the wreathing period.,almost 85% the composite mechanical behaviour is lost. From the mechanical properties result obtained it clearly seen that natural fiber and their composites are not able to stand environmental condition because they have poor wettability, incompatibility with some polymeric matrices and high moisture absorption. Due to the high moisture absorption properties, there are formations of void in interfacial adhesion between fiber and matrix which can reduce the mechanical properties of composite such as flexural strength or flexural modulus this clearly supported by SEM results. Fortunately some modification can do towards improving the mechanical properties and it is good enough to achieve the high performance of the composite with proper system formulation during the modification processand the result of reinforced kenaffiber will be presented in our next publication.
