“…The experimental tests are nowadays often coupled with numerical analyses such as finite element modelling [155][156][157]. Apart from microbond and pull-out tests, nanoindentation is frequently used to determine the interphase thickness and assess the changes therein via mapping [158][159][160].…”

This review summarizes the recent (from year 2000) advancements in the interphase tailoring of fiber-reinforced polymer composites. The scientific and technological achievements are classified on the basis of the selected strategies distinguishing between i) interphase tailoring via sizing/coating on fibers, ii) creation of hierarchical fibers by nanostructures, iii) fiber surface modifications by polymer deposition and iv) potential effects of matrix modifications on the interphase formation. Special attention was paid to report on efforts dedicated to the creation on (multi)functional interphase in polymer composites. This review is round up by listing current trends in the characterization and modelling of the interphase. In the final outlook, future opportunities and challenges in the engineering of fiber/matrix interphase are summarized.

“…Nanoindentation is a powerful technique used to directly evaluate the mechanical properties of plant cell walls, first used by Wimmer et al (1997) in the mechanical characterization of wood cell walls. Since then, this technique has found many more applications in the area of wood science and technology, including wood development (Gindl et al 2004), wood fiber composites (Lee et al 2007), and wood adhesion (Konnerth et al 2006(Konnerth et al , 2007. The mechanical testing at the macroscopic level involved the investigation of the compressive modulus of elasticity (CMOE), which is thought to be related to some extent to the cell wall indentation modulus obtained through nanoindentation testing (Yu et al 2011).…”

To better understand how moisture content (MC) affects the longitudinal compressive mechanical properties of bamboo, mechanical tests on both the macroscopic and cellular levels were performed on Moso bamboo (Phyllostachys pubescens Mazei ex H. de Lebaie) at different MCs. At the macroscopic level, the compressive modulus of elasticity (CMOE) was determined using a common mechanical tester, while the indentation modulus of elasticity (EIT) and the hardness (HIT) of the bamboo fiber cell walls were obtained using nanoindentation. The results showed that CMOE, EIT, and HIT were all negatively correlated with the change in MC below the fiber saturation point (FSP) with strong linear relationships. However, the CMOE was found to be more sensitive to a change in MC than was EIT, which indicated that the bamboo was more sensitive to MC at the macro level than at the cellular level, at least in terms of longitudinal compression stiffness. Moreover, EIT was found to be much less sensitive to a change in MC than was HIT, which may explain why the longitudinal compression strength of bamboo was much more sensitive to changes in MC than was the compression modulus of elasticity on the macro scale.

“…This technique uses the same principle as microindentation, but with much smaller probe and loads, so as to produce indentations from less than a hundred nanometers to a few micrometers in size. During the past dozen years or so, it has been widely used in measuring the mechanical properties of various nanocomposites [14][15][16][17][18][19][20][21][22][23][24][25] and human enamel and dentin [26][27][28][29][30][31][32][33][34][35][36][37][38].…”

“…It involves large plastic deformation, material nonlinearity, and contact. In order to better understand and characterize the mechanical properties and to provide guidelines for proper design of experiments, finite element method is often used to simulate the nanoindentation tests [14,15,18,[38][39][40][41][42][43][44][45][46][47][48][49][50][51]. It is also noted that the primary mechanical properties extracted from a nanoindentation test are the hardness and the elastic modulus.…”
