<br/><br/> This work involves the development of a novel siliconized epoxy  interpenetrating system using DGEBA LY556 epoxy resin as base,  hydroxylterminated polydimethylsiloxane (HTPDMS) as modifier. Triethylene  tetramine (TETA) was used as curing agent for the above system. Electrical  resistant glass (E-glass) and Spectra ultra high molecular weight polyethylene  (UHMWPE) reinforced composites are fabricated by hand-lay-up technique  using siliconized epoxy matrix systems. The effect of siloxanes and the two  fibers on the thermal, mechanical and morphological characteristics of the  siliconized epoxy polymer composites is studied using thermogravimetric  analysis (TGA), differential scanning calorimetry (DSC) and differential  mechanical analysis (DMA). The study reveals that the thermal stability of  epoxy systems is enhanced when siloxane is incorporated to them
