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
