S.  aComportamento mecânico de compósitos de resina fenólica reforçados por tecidos híbridos de juta e algodão.  c2003  aTensile properties of novolac type phenolic composites reinforced with jute/cotton hybrid woven fabrics were investigated as a function of fiber orientation and roving/fabric characteristics. Scanning electron microscopy (SEM) was carried out to investigate the fiber-matrix adhesion. Results showed that the composite properties are strongly influenced by test direction and rovings/fabric characteristics. The properties anisotropy was shown to increase with test angle and to depend strongly on type/architecture of the fabric used, i.e., jute rovings diameter and relative fiber content. Best overall mechanical properties were obtained for the composites tested along the jute rovings direction. The composites reinforced by hybrid jute/cotton fabrics are suitable for lightweight structural applications.  aResina  aCompósitos  aFibras  aInflamabilidade  aPolímeros1 aAGNELLI, J. A.
