Curing behavior, thermal and mechanical properties of epoxy/polyamic acid based on 4,4'-biphtalic dianhydride and 3,3'-dihydroxybenzidine (Polymer Engineering and Science, May 2020)

Armin Amini Majd, Mehrzad Mortezaei, Iraj Amiri Amraei

Different synthesis routes were studied to obtain 4,4'-biphtalic dianhydride (BPDA) /3,3'-dihydroxybenzidine (DHB) polyimide precursors (polyamic acids, PAAs) with different inherent viscosities and imidization degrees. The synthesized PAAs were introduced as a thermoplastic modifier into an epoxy (EP) resin. Different loadings of PAA were used to investigate the curing behavior, heat resistance, and mechanical properties. The onset curing temperature of the EP by adding 20 wt. % PAA diminished by around 15 °C. Thermogravimetric analysis revealed that the initial and 10 wt. % weight loss temperature for EP with 5 wt. % PAA improved by 13 °C and 7.7%, respectively. Further, the results of tensile and plane-strain fracture toughness tests indicated that as the amount of PAA increased, the strength and toughness of EP decreased. These improvements were due to the high heat resistance and mechanical properties of PI precursor introduced into the EP, which formed a three-dimensional structure together. The interlaminar shear strength (ILSS) of the system experienced a reduction; however, after adding 2phr nanosilica to the system containing PAA with average inherent viscosity and imidization degree, ILSS showed 4.4% increment.

Synthesis of polyamide-imide and investigation of the interpenetrating network created by its interaction with epoxy resin (14th International Seminar on Polymer Science and Technology, Under Review)

Armin Amini Majd, Amirreza Pouladvand, Iraj Amiri Amraei, Mehrzad Mortezaei

The high performance polyamide-imide (PAI, Torlon 4000T) was synthesized and different portions of PAI introduced as a reactive thermoplastic modifier into epoxy resin (EP). according to the results of FT-IR test high-performance PAI was synthesized. Curing behavior of EP/PAI revealed the onset of curing shifted back because of the acceleration effect of secondary and tertiary amines in PAI. Also, a single peak of tanδ from DMTA test was observed which is a confirmation for creaition of interpentrating network (IPN) between EP/PAI.

Improving the mechanical properties of epoxy resin and glass-fiber-reinforced epoxy composite by polyamide-imide (14th International Seminar on Polymer Science and Technology, Under Review)

Armin Amini Majd, Amirreza Pouladvand, Iraj Amiri Amraei, Mehrzad Mortezaei

Modification of the epoxy (EP) with the high performance thermoplastic polyamide-imide (PAI, Torlon 4000) was evaluated as an idea for increasing not only the toughness of the epoxy but also for escalating other mechanical properties without declining in any properties. It revealed by adding 20 wt.% PAI into EP fracture toughness, tensile modulus, and tensile strength was amplified by about 58%, 18%, and 14%. Also, the results of tensile and ILSS tests showed that enhancement in the matrix properties directly leads to significant enhancement in the properties glass-fiber-reinforced EP composite. The SEM images showed a well-blended mixture and co-continuous structure for the EP/PAI composite, which is consistent with the results of mechanical properties.

Investigation of the changes in thermal properties of epoxy resin by reaction with the polyamide-imide reactive modifier (14th International Seminar on Polymer Science and Technology, Under Review)

Armin Amini Majd, Amirreza Pouladvand, Iraj Amiri Amraei, Mehrzad Mortezaei

To investigate the effect of polyamide-imide (PAI) on the thermal properties of epoxy resin (EP), the high performance polyamide-imide (PAI, Torlon 4000T) was synthesized and different portions of PAI introduced as a reactive thermoplastic modifier into EP. The result of H NMR test showed successful synthesis of PAI. TGA tests show the addition of the PAI promoted the heat resistance of EP which is related to the reaction of different potential groups that create semi-IPN structure. Also, the DMTA result of EP/PAI systems, indicated higher elastic behavior with the addition of PAI into EP.

Synergy enhancement on the mechanical properties of glass-fiber reinforced epoxy employing polyamide-imide/nanosilica (Composite Science and Technology, Under Review)

Armin Amini Majd, Amirreza Pouladvand, Iraj Amiri Amraei, Mehrzad Mortezaei

The high performance polyamide-imide (PAI, Torlon 4000T) was synthesized and different portions of PAI introduced as a reactive thermoplastic modifier into epoxy resin to improve mechanical properties of brittle epoxy. Curing behavior of EP/PAI revealed the onset of curing shifted back because of the acceleration effect of secondary and tertiary amines in PAI. The mechanical properties of EP/PAI systems showed considerable improvement due to the creation of the semi-IPN structure. Addition of 20 wt.% PAI into epoxy results in a growth of about 18%, 14%, and 58% in the tensile modulus, strength, and fracture toughness, respectively. Besides, introducing 2 phr nanosilica into EP/PAI (20 wt.%) enhanced modulus, strength, and fracture toughness for about 26%, 18%, and 67% compared to unmodified epoxy. Glass-fiber reinforced EP/PAI composites revealed with the addition of PAI up to 20 wt.%, the tensile modulus, strength, and ILSS of composites enhanced about 25%, 11%, and 22%, respectively. Utilization of 2 phr nanosilica in EP/PAI (20 wt.%) composites showed 36%, 23%, and 32% improvement in tensile modulus, strength, and ILSS properties, respectively.
