Study of the tensile strength of a polymer composite material based on ABS-plastic and impregnated in epoxy resin with different types of hardener

Abstract

Annotation This article examines the study of strength properties of polymer composite material, based on 3D-printed frame produced by FDM technology. The printing material is ABS plastic (acrylonitrile butadiene styrene). After the printing samples frames were soaked in pure epoxy resin with various hardeners. Subsequent curing went in two modes. After that, tensile tests were performed. The strength of impregnated, non-impregnated (clean frame) samples and samples made of pure resin was compared. Tests have shown that the strength of impregnated samples exceeds the strength of non-impregnated ones, but obtained strength value of impregnated samples were far from the expected theoretical values. It was found that low strength is associated with poor quality of the impregnation.

Effects of a new filling technique on the mechanical properties of ABS specimens manufactured by fused deposition modeling

“…The ultimate tensile strength obtained was 44.8 ± 1.1 MPa, and elongation at break was of 10.3 ± 0.03%. This result is higher than the tensile strength obtained by Filippova et al [25], and it is related to the chemical composition, since the hardeners tested by Filippova et al were triethylenetetramine (TETA) and polyethylene polyamine (PEPA) which resulted in tensile strength of 22.4 MPa and 22.7 MPa, respectively. On the other hand, Halder et al [32] used a resin of bisphenol-A and amine-based hardener so their results were very close to the results in this paper as they recorded 41.92 MPa as best tensile strength.…”

“…Nanoparticles were prepared and mixed with the printing filament to produce a new one [9,[21][22][23]. Some researches focused on improving the overall mechanical properties of the 3D printed part by decreasing its anisotropy or increasing its isotropic behavior [24,25]. They replaced the thermoplastic polymers that result in poor chemical and thermal properties with two-component epoxy resin [24], epoxy resin has good chemical and physical properties and gives high-strength bonding, with light weight structures withstanding high static loads [26][27][28].…”

Filippova et al [25] impregnated ABS 3D printed samples in epoxy resin compound with different hardeners. 142% and 133% were achieved as an improvement in ultimate tensile strength depending on the hardener type.…”

“…Кроме того, существуют различные методы упрочняющей постобработки изделий. Один из них -вакуумная пропитка в полимерных компаундах [10][11][12][13][14].…”

Eklemeli imalat yöntemlerinde vakum infüzyon yolu ile üretim optimizasyonu

“…Lopatine ve Slavkina, Filippova vd. tarafından yapılan çalışmalarda vakum ile reçine emdirilerek bu iyileştirmelerin yapılabileceği önerilmektir [27], [28]. Bu çalışmada, vakum infüzyon yönteminin, eklemeli imalat metotlarında üretim hızını ve parça mukavemetini arttırdığı, üretim maliyetini düşürdüğü yapılan deneylerle kanıtlanmıştır.…”
