“…The possibility of mixing different types of reinforcement is interesting: the natural reinforcement is recyclable and it allows that tailor made mechanical properties to be obtained. Thus, a balance between environmental impact and performance can be achieved [11][12][13] . Jawaid and Khalil 13 cited recent relevant studies about polymer hybrid composites, and a limited number of studies related to hybridization of ramie with another natural or synthetic fiber.…”

The use of ramie fibers as reinforcement in hybrid composites is justified considering their satisfactory mechanical properties if compared with other natural fibers. This study aims to verify changes in chemical composition and thermal stability of the ramie fibers after washing with distilled water. One additional goal is to study glass fiber and washed ramie fiber composites focusing on the effect of varying both the fiber length (25, 35, 45 and 55 mm) and the fiber composition. The overall fiber loading was maintained constant (21 vol.%). Based on the results obtained, the washed ramie fiber may be considered as an alternative for the production of these composites. The higher flexural strength presented being observed for 45 mm fiber length composite, although this difference is not significant for lower glass fiber volume fractions: (0:100) and (25:75). Also, by increasing the relative volume fraction of glass fiber until an upper limit of 75%, higher flexural and impact properties were obtained.

“…According to Reddy [30], hybridization has the potential of making natural fabric composites more suitable for technical applications such as automotive interior parts. Recent literature on that may be found for the hybridization of sisal/glass [31][32][33][34][35], Bambu/glass [36], hemp/glass [37], palm fiber/glass [38], jute/glass [39,40], curaua/glass [41], kapok/glass [30], kapok/sisal [30] and roselle/sisal [42], among others.…”

Concerns related to the ever-growing use of raw-materials from non-renewable sources by modern society is driving the interest of the academic and scientific sectors for a new concept of material, which takes into account not only mechanical performance, cost and availability, but also environmentally-related issues, such as biodegradability, renewability and energy use, along with the promotion of social and economical development of the economically-challenged segment of the population. Vegetable fibers have been used in many home-made objects, such as ropes and artcraft, for perhaps as long as humanity exists. However, these fibers present a combination of interesting properties which enables their use in a wide variety of sectors. This invited article will review the work recently carried out by the author in collaboration with various researchers from UFRGS, UFPR and UCS, and will be divided into three case studies, focusing on the use of vegetable fibers for oil sorption, as infiltration (flow) medium and as reinforcement for polymer composites, promoting their use in more demanding and rewarding applications.

“…According to the study by Paiva et al [17], addition of 45% volume fraction of rami fibers into polyester increased the TS of polyester by about 338%. Vieira et al [18] studied 25% sisal/glass fiber reinforced composites and revealed that increasing the glass fiber content ratio caused higher tensile and impact strengths. Hybridization studies on the properties of the cellulosic/synthetic fiber reinforced polymer composites show that tensile, flexural and impact properties were increased and water absorption behavior was recovered [19][20][21][22].…”

A new approach for the development of textile waste cotton reinforced composites (T-FRP): laminated hybridization vs. coupling agentsAbstract: This paper presents two separate methods to improve the tensile strength (TS) of textile waste cotton reinforced polymer composites (T-FRP) as prospective functional materials with respect to environmental concerns. Two very different methods were designed in order to improve the TS of the composite. In the first method, maleated anhydride polyethylene was added as the coupling agent into the composite composition, whereas in the second method, a totally new glass fiber and glass fabric laminated hybrid composite structure was designed. In this first study, the coupling agent was mixed up to 5 wt% into the composite structure in order to improve the bonding interface between low density polyethylene (LDPE) matrix and cotton waste fibers. The effect of the coupling agent was evaluated and compared with the unmodified one. By contrast, chopped glass (CG) fibers and woven biaxial glass fabrics were introduced into the composite layers with the intention of designing a new hybrid composite structure as a second study. The TS of the materials was evaluated and the fracture surface was assessed with an optical microscope. Consequently, an improvement in TS of 50% and 230% was achieved by the addition of the coupling agent and the creation of a new hybrid composite, respectively.

Characterization of hybrid composites produced with mats made using different methods

Abstract: The sisal rope was cut into 3 cm long fibers and the fibers were washed (100 mL of water per gram of fiber) in distilled water for 30 minutes. The fibers were dried in an oven with ventilation for 180 minutes at 60 °C.
