“…Glass was studied extensively by Dutschk et al,19 and their findings indicated that the technique of IGC is “too sensitive to give an unambiguous description of the complex character of heterogeneous fibers”; however, because a rule of mixtures worked with the complicated polyester system and because this glass is sized for polyester, the technique may apply. Park and Kim7 determined the total surface energy of polyester‐sized glass fibers to be approximately 38 mJ/m 2 . The value found with IGC is somewhat higher than the value found by Park and Kim but is consistent with IGC values being higher than contact‐angle analysis values.…”

“…The surface energies determined for two types of glass fibers were 29.37 and 26.57 mJ/m 2 . Park and Kim7 also used wicking experiments to determine the total surface energy of polyester‐sized glass fibers to be approximately 38 mJ/m 2 . In the following study, inverse gas chromatography (IGC) results are used to determine the dispersive surface energies of a commercial glass‐fiber reinforcement.…”

Sheet molding compound is a material composed of a polyester thermosetting matrix with a thermoplastic, an inorganic filler, a metal oxide, reinforcement fibers, and material performance enhancers embedded in the crosslinked matrix. To achieve the optimum mechanical properties required for the composite material, the surface free energy of the polyester composite needs to be understood. In this study, the composite matrix and glass reinforcement fibers are compared with respect to their surface free energy and acid-base characteristics on the basis of inverse gas chromatography measurements. The inverse gas chromatography results for the matrix and glass are compared to previous results found for sized and unsized cellulosic fibers. The inverse gas chromatography data are used to assess chemical modifications performed on the biobased fibers to predict improvements in the fiber/matrix interaction, and this provides inferences on the overall composite cohesion. Our results show first that any fiber reinforcement system for the polyester composite material has to be acidic to promote good adhesion as the matrix system is very basic and second that the individual dispersive surface energies of the components of the matrix interact in a weighted average to determine the overall surface energy of the composite. Also, a commercial glass reinforcement sized for polyester has been found to have a lower interaction parameter than literature values for cellulosic fibers. This finding suggests that cellulosic fibers might have an advantage in competing with a conventional glass-fiber reinforcement system in fiber/matrix bonding for sheet molding compound composites.

“…Because of its unique properties, high specific strength, strong designability, and easy processing, fiber/polymer composites have been rapidly developed and extensively used in aerospace, weaponry, rail transit, and other industrial fields. [ 1–6 ] Currently, the service temperature of fiber/polymer composites applied in the above fields is getting higher and higher, and the research on high temperature mechanical properties has become one of the key research directions for fiber/polymer composites. [ 7 ] Furthermore, the tensile strength, which belongs to the crucial mechanical property's indicators, is strongly affected by temperature and the damage condition of materials.…”

With the rapid development of aerospace technology, the application of fiber/ polymer composites in extreme environments especially at high temperature gets more and more extensive, the tensile properties of fiber/polymer composites in different temperatures environment have become a critical issue of concern. In this work, a temperature and damage dependent tensile strength (TDDTS) model for fiber/polymer composites was presented based on the force-heat equivalence energy density principle and the damage failure analysis. The TDDTS model considers the combined effects of temperature, the evolution of constituents' properties and damage with temperature. Meanwhile, the TDDTS model has advantages from the aspects of prediction accuracy and convenience by comparison with our previous model and the Curtin's model.Further on, the influencing factors analysis of fiber/polymer composites concerning the tensile properties and damage evolution with temperature was conducted. This study offers a reliable model for predicting the TDDTS of fiber/polymer composites, and provides important insight for the strength degradation mechanism and the damage evolution.
