“…As aplicações aeronáuticas têm sido uma das principais motivadoras no desenvolvimento da tecnologia dos adesivos, devido aos materiais compósitos serem mais bem unidos com a utilização de adesivos, ao invés dos métodos tradicionais de união, tais como: soldagem, parafuso, rebite, etc. (WAMBUA;IVENS;VERPOEST, 2003;PEREIRA et al, 2020).…”

“…Em um outro estudo com hibridização de fibras vegetais, Pereira et al (2020) A colagem de compósito com um outro material não é tão simples de ser feito, devendo ter cuidados na preparação da união desses materiais (PEREIRA; PEREIRA, 2022). A tecnologia dos adesivos, as juntas adesivas e os compósitos se desenvolvem ao mesmo tempo, pois a união desses materiais é preferida através de colagem adesiva (BANEA; DA SILVA, 2009;BUDHE et al, 2017;PEREIRA;PEREIRA, 2023).…”

RESUMO: O tema de estudo deste trabalho são os compósitos reforçados com fibras vegetais e o processo de colagem entre materiais diferentes. Aplicações na aeronáutica tem sido uma das principais motivações no desenvolvimento da tecnologia dos adesivos. No entanto outras áreas também usam essa tecnologia, exemplo: automotiva e esportiva. A união de compósitos é preferida utilizando adesivos, devido a outros métodos conhecidos de união, por exemplo: solda, parafuso ou rebite, diminuírem sua resistência mecânica. Diante disso, o objetivo desta pesquisa foi avaliar diferentes comprimentos (12,5 mm e 25,0 mm) de um adesivo epóxi em juntas de sobreposição simples entre dois materiais: compósito e alumínio. As fibras vegetais de reforço utilizadas nos compósitos foram Sisal + Curauá (S + C) e Juta + Curauá (J + C). A metodologia utilizada foi ensaio à tração nas juntas adesivas simples em pelo menos 3 corpos de prova de cada tipo (S + C e J + C) com apoio das normas ASTM D1002 e D3163 para o ensaio experimental e as dimensões das juntas de sobreposição simples. Os principais resultados obtidos foram uma maior resistência mecânica no compósito de J + C de comprimento de colagem de 12,5 mm e que o aumento do comprimento e área de colagem foi inversamente proporcional a resistência mecânica das juntas de sobreposição simples.

“…Literature review shows that the hybridization technique can be used to reduce water absorption and improve the mechanical properties of natural fibre reinforced composites [20,21]. Hybridization uses two or more reinforcement materials in a single matrix phase to exploit different properties of these reinforcements while retaining their individual properties in the resultant composites [22][23][24]. us, hybridization of natural fibres with synthetic fibres improves the mechanical strength of natural fibre reinforced composites [25].…”

The global drive towards a circular economy that emphasizes sustainability in production processes has increased the use of agro-based raw materials like natural fibres in applications that have long been dependent on inorganic raw materials. Natural fibres provide an eco-friendly, more sustainable, and low cost alternative to synthetic fibres that have been used for a long time in the development of composite materials. However, natural fibres are associated with high water absorption capacity due to their hydrophilic nature leading to poor compatibility with hydrophobic polymeric matrices, thus lower mechanical properties for various applications. Hybridization of natural fibres with synthetic fibres enhances the mechanical performance of natural fibres for structural and nonstructural applications such as automobile, aerospace, marine, sporting, and defense. There have been increased research interests towards natural/synthetic fibre hybrid composites in the past two decades (2001–2021) to overcome the identified limitations of natural fibres. Therefore, understanding the parameters affecting the properties and potential of using natural and synthetic fibre reinforcements to develop hybrid composites is of great interest. The review showed that using appropriate fibre orientation, fibre weight fraction and stacking sequence yields good mechanical, physical, and thermal properties that are competitive with what only synthetic fibre reinforced composites can achieve. In addition, these properties can be improved through pretreatment of natural fibres using different chemicals. This paper provides in review form the parameters affecting the mechanical, physical, and thermal properties of natural/synthetic fibre hybrid reinforced polymer composites from the year 2001 to 2021.

“…3,4 With these considerations in mind, natural fibre reinforced composites (NFRCs), have been intensively studied in recent years. [5][6][7][8][9][10][11][12] However, one of the main drawbacks of NFRCs is their relatively low mechanical properties when compared to synthetic fibre-reinforced composites. One method studied in the literature to improve the mechanical properties of NFRCs is the hybridization.…”

In this work, a comparative analysis of the mechanical and thermal properties of polyester and epoxy single and hybrid natural fibre-reinforced composites was performed. Pure jute, jute + curauá and jute + sisal composites with two distinct thermoset polymer resins (an epoxy and a polyester) were produced. Tensile, flexural and impact tests were carried out, in accordance to ASTM standards, to investigate and compare the mechanical properties of the composites as a function of matrix and hybridization. In addition, a thermogravimetric analysis (TGA) was used to complete the comparative analysis of the thermal properties. Finally, a scanning electron microscopy (SEM) was used to examine the fracture surface of the tested specimens. It was found that the hybridization process improved the mechanical properties of the non-hybrid jute fibre based composites for both matrices used. The resin used as matrix plays an important role on the mechanical properties of the composites. The epoxy matrix based composites presented higher tensile strength, while the polyester based composites presented higher tensile and flexural stiffness as well as higher impact energy, when compared to the epoxy-based composite. TGA analysis showed that the thermal stability of epoxy-based composites was higher compared to the polyester-based composites.
