“…At high fibre loading, fibre agglomeration may occur, creating more fibre to fibre contact instead of fibre and matrix interaction. Consequently, when there is more fibre to fibre contact, the effective stress transfer from the matrix to fibre is harder to achieve (Rojo et al 2015). The impact at low fibre loading (10%) was slightly lower than that at 20% fibre loading because of the poor fibre population caused by low load transfer capacity among the fibres.…”

Roselle (Hibiscus sabdariffa L.) bast fibre reinforced vinyl ester (VE) was prepared using a hand lay-up method and an internal mixer. The composite samples were prepared under two different parameters: with various fibre contents; and without fibre (neat VE). The mechanical properties (tensile and impact strength) and thermal properties were investigated. The morphological properties of impact fracture samples were studied using a scanning electron microscope (SEM). Roselle fibre reinforced VE (RFVE) composites showed increased tensile strength and tensile modulus. The highest tensile strength and modulus were at 20vt% fibre loading. However, impact strength decreased as the fibre loading increased. SEM showed that there was good fibre/matrix adhesion and fibre dispersion for 20% fibre loading, which was reflected in the good tensile strength properties. However, fibre agglomeration was seen at higher fibre loads. The results from thermogravimetric analysis (TGA) and derivative thermogravimetric analysis (DTG) showed three major degradations of the RFVE, which were the loss of moisture content, degradation of hemicelluloses, and degradation of cellulose. The thermal analysis showed enhancements in the residual content of the composite materials, thereby improving the thermal stability. However, there was no major difference seen in the degradation temperature.

“…It controls the elongation of the composite during breakage by reducing impact energy absorption. Agglomeration also occurs on it at high fibre loading, causing fibre-to-fibre contact that reduces the stress transfer between the fibre and the matrix, resulting in composite failure [18][19][20].…”

“…Since it is calculated from the total area under the stress–strain curve up to fracture point, therefore SED takes into account and illustrates the overall behavior of the mechanical properties, namely, strength, modulus, and elongation. In fact, attaining a maximum in the flexural properties of short fiber‐reinforced composites is the attribute most often found in the literature .…”

Recently, the concept of high solids loading in ionic liquid (IL) based pretreatment of lignocellulosic biomass has gained numerous attention due to significant economic, environmental, and sustainability benefits. The objective of the present work was to investigate the impact of ILs pretreatment of lignocellulosic oil palm frond (OPF) biomass at high solids loading on the mechanical and thermal properties of the composite panels. The process combines the pretreatment of OPF particles with ILs [bmim][Cl] (1‐butyl‐3‐methylimidazolium chloride) and [emim][OAc] (1‐ethyl‐3‐methylimidazolium acetate) followed by IL recovery by rinsing with acetone‐water mixture prior to mixing of OPF particles with polymer binder to fabricate compression‐molded composite panels. Untreated and treated OPF particles were characterized by scanning electron microscopy, X‐ray diffraction, thermogravimetric analysis, and chemical composition analysis. Further, the effect of ILs pretreatment on kinetics of thermal degradation of biocomposites was evaluated by activation energy approach. Maximal flexural strength, modulus, and strain energy density (SED) of 25 MPa, 1,928 MPa, and 0.48 MJ/m3, respectively, were found for IL [emim][OAc] treated composite. Besides, thermal properties of IL treated composites were also improved. Present study could be a significant step toward practical IL pretreatment strategies for manufacturing of lignocellulosic based composite materials. POLYM.
