“…Therefore, it can be stated that wettability may increase due to increase of bonding surface. 1,4,20 After APPLJ treatment, it was determined that when the impurities were removed for all types of gas, not only the surface cleanliness (Figure 8(d)) but also some roughness and small pits were appeared on the treated surface (Figure 8(c)). In cases where the plasma did not exhibit sufficient effect, the remaining impurities (figure 8(f)) on the surface prevented fibrillation (Figure 8(e)) and caused insufficient wettability properties.…”

“…In order to be able to correct this, the polarity, roughness, reactivity and wettability of the reinforcement surface must be changed without changing the bulk properties. [1][2][3][4][5] In studies carried out on composite materials containing natural reinforcements, the surface treatment of natural reinforcement by chemical methods is quite common. [6][7][8][9] But, the length of the chemical treatment process and the environmental damage caused by the chemicals has led to a tendency towards the alternatives to this method in recent years.…”

“…In another study using low frequency and radio frequency plasma (low pressure 0.1-0.3 mbar), the jute fiber-reinforced composite exhibited increased inter laminar shear strength with increasing plasma power. 4 If the surface free energy change in the fiber or its components are taken into account, the changes in the plasma process of the basic components, such as cellulose, affect the compatibility of the fiber with the matrix. In a cellulose conducted study, it was reported 14 that the contact angle, which is one of the surface free energy indicators of the nitrogen plasma-treated cellulose, increased for the short processing times and after a point the new functional groups appearing on the surface caused hydrophilic tendency.…”

This study reports on the effect of atmospheric pressure plasma jet treatment on the flax fiber and flax-reinforced epoxy. The atmospheric pressure plasma jet was carried out by using four different gasses and various application distance in the range of 30–40 mm. The treatments were investigated by means of contact angle, attenuated total reflectance–Fourier transform infrared spectroscopy, atomic force microscopy, scanning electron microscopy and mechanical tests. Depending on the application parameters, the rate of increase in water contact angle varied from 49% to 92%. While atomic force microscopy and scanning electron microscopy investigations exhibited changed surface morphology, FTIR presented interactions at the molecular level. Improvement in mechanical properties was obtained for all atmospheric pressure plasma jet applications, while the increase in tensile strength in the composite material reached 180%, and the increase in flexural strength was 140%. The atmospheric pressure plasma jet method, according to similar plasma applications, came to the forefront with the short processing time and the intensity of the effect it created.

“…Tais características induzem aos compósitos uma perda das propriedades mecânicas [2,20,26,27] . A fim de melhorar a adesão polímero/fibra e reduzir a absorção de água, a superfície das fibras pode ser modificada por métodos físicos ou químicos [18,28,29] . As propriedades destes materiais podem ser aprimoradas, se ocorrer intensificação nas interações entre a fibra e a matriz [30] .…”

Resumo: Neste trabalho, foram utilizadas fibras de curauá como reforço de matriz termoplástica de biopolietileno de alta densidade. O polietileno foi obtido por polimerização de eteno, gerado do etanol de cana de açúcar. Este polímero é também chamado de biopolietileno (BPEAD), por ser preparado a partir de material oriundo de fonte natural. Desta forma, pretendeu-se contribuir para desenvolver materiais que, dentre outras propriedades, causem menor emissão de CO 2 para a atmosfera na sua produção, utilização e substituição, comparativamente a outros materiais. Adicionalmente, polibutadieno líquido hidroxilado (PBHL) foi acrescentado à formulação do compósito, visando a um aumento na resistência à propagação da trinca durante impacto. Os compósitos e as fibras foram caracterizados por várias técnicas, tais como microscopia eletrônica de varredura (MEV), Calorimetria Exploratória Diferencial (DSC), Termogravimetria (TG), além da caracterização dos compósitos quanto à Análise Térmica Dinâmico-Mecânica (DMTA), propriedades mecânicas (impacto e flexão) e absorção de água. A presença das fibras de curauá diminuiu algumas propriedades do BPEAD, como resistência ao impacto. A análise de DMTA mostrou que as fibras geram material mais rígido. Pode-se considerar que a introdução de PBHL na formulação do material foi eficiente, levando a uma resistência ao impacto do compósito BPEAD/PBHL/Fibra maior do que a do compósito BPEAD/Fibra.

Preparation and Characterization of Biocomposites Based on Curaua Fibers, High-density Biopolyethylene (HDBPE) and Liquid Hydroxylated Polybutadiene (LHPB)Abstract: In this work, curaua fibers were used in the reinforcement of a high-density (HDPE) thermoplastic matrix. The polyethylene used was obtained by polymerization of ethene produced from sugarcane ethanol. This polymer, also called high-density biopolyethylene (HDBPE), was prepared from a natural source material. The aim was to contribute to developing materials which could lead to smaller release of CO 2 into the atmosphere in comparison to other materials. Additionally, liquid hydroxylatedpolybutadiene (LHPB) was added to the composite formulation, aiming at improving resistance to crack spreading during impact. The fibers and their composites were characterized by several techniques, such as scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and thermal gravimetry (TG). The composites were also characterized by dynamic mechanical thermal analysis (DMTA), mechanical properties (flexural and impact strength), and water absorption. The presence of curaua fibers reduced some of the properties of HDBPE, such as flexural and impact strength. DMTA indicated a more rigid material with the fibers incorporated. The addition of LHPB to the formulation was efficient, leading to greater impact strength for the HDBPE/LHPB/Fiber composite, as compared to the HDBPE/Fiber composite.
