The paper studies new high-temperature thermoplastic impregnated unidirectional carbon fiber composites. research focuses on the effect of thermal and chemical oxidation fibers surface interfacial interaction between polysulfone polyphenylene sulfide as well mechanical properties reveals polymer matrix depend both type treatment nature polymer. results in good interaction, best were observed for tows with sulfide.
Interfacial interaction is one of the most important factors that affect mechanical properties fiber reinforced composites. The effect fabrics′ sizing removal from glass fibers’ surface by thermal treatment on characteristics polyethersulfone based composites at different to polymer weight ratios was investigated. Three 50/50, 60/40, and 70/30 were studied. Flexural shear tests carried out illustrate composites; structure studied using Fourier-transform infrared spectroscopy scanning...
In this study, the interlaminar fracture toughness and impact strength of polyethersulfone reinforced with continuous carbon fibers were studied. Interlaminar tests performed using double cantilever beam method. It was shown that surface modification thermal oxidation method can strongly increase obtained composites. Thus, maximum value reached 1.72 kJ/m2, which 40% higher than composites initial fibers. Moreover, fractographic analysis a scanning electron microscope allowed us to highlight...
Highly oriented UHMWPE films were reinforced with functionalized graphene nanoplates (GNP). GNP was by deposition of polyaniline (PANI) on the surface. The structure GNP/PANI studied Raman spectroscopy, and xerogels based DSC SEM. PANI promotes reduction aggregation in matrix increases degree crystallinity due to heterogeneous crystallization. new lamellar crystal has a high drawability. highest value tensile strength 1330 MPa (an increase 45%) obtained filler content 2 wt % GNP/PANI,...
