“…The role of fibre surface properties and also the interface made with a resin matrix have been paramount consideration in the natural fibre composite industry since its inception 1. 2 Recognizing this fact, technologists are striving continuously to improve the hydrophobicity, wetting and adhesion properties of natural fibres (with a resin matrix) through immobilization of suitable chemical functional species on their surfaces to achieve improved composite mechanical performance 3–8. However, in most cases, the failure of composites is considered as interphase‐controlled due to a lack of good fibre‐matrix bonding 9.…”

“…This reinforces the fact that both lignin and hemicelluloses hold up well under transverse forces [11]; thus, the cell walls undergo fewer alterations to their structure as a result of these forces. This being so, the endocarp-rich regions would show good compressive strength owing to the high amount of lignin in these regions [7].…”

The aim of this study was to investigate the damage mechanism and the influence of excessive exposure to moisture on the mechanical behavior of alternative configurations of glass fiber reinforced plastic (GFRP). There are several possible applications involving pipes, storage tanks, and roof tiles, among others. A mat-shape hybrid configuration composed of a glass fiber reinforced polyester matrix was designed using continuous roving, along with an alternative hybrid filler, derived from two different types of industrial residues: from the furniture/wood and coconut (Cocos nucifera Linn) by-product industries. A plate configuration was initially developed and manufactured industrially. The granulometry used for the hybrid filler had a 50/50 endocarp/wood weight ratio for each residue. The resin-tohybrid filler ratio was 65/35, representing the ratio for the manufacture of 480 g of resin and 260 g of residue. The initial goal, given the possible application of the composite developed in pipes and storage tanks, was to conduct a study aimed at analyzing its mechanical behavior in the face of excessive moisture, characterized by moisture saturation of the material. The mechanical properties of strength and stiffness were studied using tensile uniaxial and three-point bending tests in the dry and saturated moisture tests. To this end, a preliminary moisture absorption test was conducted. The damage mechanism developed was crucial for a better understanding of the interface behavior in the distribution of the laminated layers.

“…In addition, the amount of moisture sorption can be reduced significantly through the replacement of natural fibers with a small amount of synthetic fibers, such as glass or carbon . Hybridization with hydrophobic fibers provides a method to improve the mechanical properties of natural fiber composites and its effect in different modes of stress depends on the design and construction of the composites . Many techniques have been used to provide evidence for the effect of these treatments on the fiber–matrix interfacial adhesion.…”

Effect of Alfa fiber mechanical separation on dielectric properties of hybrid unsaturated polyester composites

An exhaustive study of dielectric and impedance analysis on two Alfa‐fiber‐reinforced unsaturated polyester hybrid composites was performed. Alfa fiber reinforcements were hybridized by wool and PE/PET fibers in the relative volume fraction ratio 17:2:1. However, these reinforcements differ by the number of mechanical separation of Alfa fibers in the Shirley analyzer. For Composite (1), Alfa fibers were separated mechanically once in the Shirley analyzer whereas for the Composite (2), they were separated mechanically twice in the Shirley analyzer. Dielectric parameters analysis (ɛ′, ɛ″) revealed the presence of the α‐relaxation process at intermediate temperature range for the matrix and the water dipoles polarization at low temperatures for the Composite (1). No dynamic dielectric relaxation was observed for the Composite (2) at low temperatures. However, dielectric properties were controlled by the dc conductivity effect at higher temperatures. The Kramers‐Kronig relation was used to eliminate its effect. Hence, α mode relaxation was observed for the matrix and the interfacial polarization effect was observed for its composites. The attenuated effect of this latter for the Composite (2) was attributed to its homogeneous structure. Electrical conductivity analysis using the Jonscher law allowed determining the transport mechanism for all studied materials and confirmed such result. Complex impedance analysis supported the homogeneous structure for the Composite (2). POLYM. COMPOS., 40:1774–1785, 2019. © 2018 Society of Plastics Engineers
