ORIGINAL PAPER Fabrication of adduct filled glass fiber/epoxy resin laminate composites and their physical characteristics Cuong Manh Vu 1 • Thai Viet Nguyen 1 • Liem Thanh Nguyen 2 • Hyoung Jin Choi 3 Received: 28 April 2015 / Revised: 1 October 2015 / Accepted: 2 November 2015 Ó Springer-Verlag Berlin Heidelberg 2015 Abstract Adducts were synthesized from thiokol and epoxy resin using triethy- lamine as a catalyst, and their structure and molecular weights were determined. The synthesized adducts, which possessed an epoxide group on their chain as a modifier to enhance the toughness of the epoxy resin, were well dispersed in the epoxy matrix, resulting in the successful manufacture of laminate composites made from glass fiber/epoxy resin (GF/EP). The microstructure and mechanical proper- ties, such as the tensile strength, impact resistance and mode I interlaminar fracture toughness, were investigated and compared with those of the GF/EP system. The addition of the adduct to the epoxy matrix led to an increase in both the mode I interlaminar fracture toughness and IZOD impact resistance of the GF/EP. Keywords Epoxy resin Composite Adduct Impact strength Interlaminar fracture toughness Introduction Lightweighting is a concept that replaces traditional materials, such as construction steel and aluminum, with advanced metal alloys and composites to achieve significant weight reductions and reduced energy use.
