“…Moreover, when the fiber behavior was non-regular, a load drop was frequently observed during loading, which can be attributed to the moment when the filaments started splitting from each other, leading to fibrillation. In general, fibrillation might be considered to improve fiber-matrix adhesion; as a matter of fact, mechanically induced fibrillation has been already used on bamboo-PLA composites to make them more suitable to processing techniques, such as extrusion, pelletizing and subsequent injection molding [37]. However, when fibrillation occurs, pull-out tests usually overestimate the value obtained for the interfacial shear strength because mechanical interlocking could contribute to a stronger connection of the technical fiber (through its elementary fibers) to the polymeric matrix.…”

Abstract:In this work, the apparent shear strength at the interface between a bamboo fiber and the surrounding poly(lactic acid) (PLA) matrix is quantified. A method for processing pull-out test samples within a controlled embedded length is proposed and the details of the test procedure are presented, along with a critical discussion of the results. Two series of samples are considered: untreated and mercerized bamboo fibers from the same batch, embedded in the same polyester matrix. Electron and optical microscopy are used to observe the fiber-matrix interface before and after the test, and to identify the failure mode of each sample, especially as regards the occurrence of fibrillation in the fiber bundles. The values of apparent interfacial shear strength are calculated only for regular fibers successfully pulled out from the matrix, and reported with their statistical variations. Mercerization, whose efficiency was proven by Fourier transform infrared (FTIR) spectroscopy, did not appear though to improve the quality of the interface (τ app = 7.0 ± 3.1 MPa for untreated fibers and τ app = 5.3 ± 2.4 MPa for treated fibers).

RbstractThe need to develop and commercialize materials containing vegetal fibers has grown in order to reduce environmental impact and reach sustainability. Large amounts of lignocellulosic materials are generated around the world from several human activities. The lignocellulosic materials are composed of cellulose, hemicellulose, lignin, extractives and ashes. Recently these constituents have been used in different applications; in particular, cellulose has been the subject of numerous works on the development of composite materials reinforced with natural fibers. Many studies have led to composite materials reinforced with fibers to improve the mechanical, physical, and thermal properties. Furthermore, lignocellulosic materials have been treated to apply in innovative solutions for efficient and sustainable systems. This paper aims to review the lignocellulosic fibers characteristics, as well as to present their applications as reinforcement in composites of different polymeric matrices.

“…Advancing and receding contact angles of various test liquids were measured on the technical flax fibres under controlled conditions (see section 2.2), with a Krüss K100 tensiometer using the Wilhelmy technique [6,13]. The selection of water, diiodomethane, and ethylene glycol as test liquids is based on the difference of surface energy components between them (water is presumed predominantly acidic, ethylene glycol is basic, and diiodomethane is a non-polar liquid), according to the Van Oss model [14] and the scale proposed by Della Volpe [15].…”

“…Finally, extractives are a mixture of small molecular weight individual compounds such as fats, waxes, and phenolic constituents [5]. Most of them are easily removed during fibre extraction processes, but even a very small amount remaining on the fibre surface can affect the interfacial properties of composites reinforced with plant fibres [6].…”

The influence of moisture content in the environment during manufacture of a novel cobalt-free UP matrix reinforced with flax fibres, on the fibre-matrix adhesion was studied. Flax surface energy was experimentally determined by measuring contact angles on technical fibres, using the Wilhelmy technique and the acid-base theory. The mechanical strength of the interface under different humidity conditions was characterized by the critical local value of interfacial shear stress, τ d , at the moment of crack initiation, which was assessed by single-fibre pull-out tests. Differential scanning calorimetry and x-ray photoelectron spectroscopy analysis gave further insight into the topic. The results suggest that the effect of humidity during manufacturing on the composite interface might be limited. However, longitudinal composite strength decreased somewhat for composites produced in humid conditions, showing that there is some detrimental effect of high levels of moisture during cure on the fibre mechanical performance, likely caused by some fibre degradation.
