Thermal expansion of organic and inorganic matrix composites: A Review of theoretical and experimental studies

Abstract

This paper reviews theoretical and experimental studies conducted in organic, ceramic, and metal matrix composites containing cylindrical, lamellar, and spheroidal inclusions as reinforcements. Mathematical formulations proposed to predict thermal expansion coefficients of fiber, disc, and sphere reinforced organic and inorganic matrix composites have been reviewed. Experimental studies undertaken to confirm theoretical predictions of thermal expansion coefficients of a variety of reinforcement geometry composites have also been discussed.

The influence of hardener-to-epoxy ratio on the interfacial strength in glass fibre reinforced epoxy composites

“…Several models have previously been proposed [9][10][11][12][13] to quantify the formation of the thermal residual stresses at the interface due to differences in the coefficients of expansion of the matrix and fibre. Nairn [9] proposed a model to calculate the σ R that accounted for the effects of differences in the axial and transverse fibre properties:…”

“…Discussions about the interface in composites typically focus on the chemistry of the matrix system and the necessity to maximise the level of chemical bonding between the fibre and the matrix in order to optimize the level of 'adhesion' between the two [1][2][3][4][5][6]. However a number of authors have also commented on the potential role that shrinkage stresses may have in influencing the stress transfer capability of the interface [7][8][9][10][11][12][13]. Specifically, that residual radial compressive stresses (σ R ) formed at the interface may be a significant contributor to the measured strength of the interface.…”

Dielectric, thermal and mechanical properties of zirconium silicate reinforced high density polyethylene composites for antenna applications

“…3(a)). 53,54 In HDPE-ZrSiO 4 composites, the linear decrease in CTE with the filler volume fraction indicates that the matrix-filler adhesion is good enough to withstand the thermal stress. 3(a)).…”

A review on new mesostructured composite materials: Part II. Characterization and properties of polymer–mesoporous silica nanocomposite

“…Organic–inorganic materials, especially the composites consisting of the polymeric phase and inorganic nanofillers, are of considerable interest and importance because they give rise to a synergy between the inorganic particles and the polymer matrix, thereby providing materials with better properties which can be used in various applications. 1–4…”
