Abstract

Stretching calorimetry technique was used to evaluate Young's moduli (E), linear expansivities (αL) and internal energy changes (ΔU) in stretching/contraction cycles for single carbon fiber/ polycarbonate (CF/PC) microcomposites. Within the interval of elastic strains, microcomposites with both sized and unsized CF were characterized by significantly higher values of E and ΔU and by lower values of αL compared to the plain PC matrix. The results obtained suggest the formation of interfacial boundary PC layers with changed structure around CF which affect the thermoelastic properties of the CF/PC microcomposites.
