“…A preliminary design was established using six injection parameters: the material temperature ( T ma ), the injection pressure ( P inj ), the holding pressure ( P h ), the mold temperature ( T mo ), the holding time ( t h ), and the cooling time ( t c ). Reference values and range of variation were taken from the previous works on PC/ABS blend, the material data sheet, and the SKG experience. The parameters related to the injection machine capacity were the mold temperature ( T mo ), the injection pressure ( P inj ), and the holding pressure ( P h ).…”

Polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS) possess thermal and mechanical properties, which make them materials of choice for automotive components. These properties have presented PC/ABS as an eligible replacement for metals in automotive industry. The aim of this study was to explore a new approach to determine the optimum conditions for obtaining quality and shear stresses of the injected and metalized PC/ABS parts. For this purpose, the following six injection-molding parameters such as material temperature (T ma ), injection pressure (P inj ), holding pressure (P h ), mold temperature (T mo ), holding time (t h ), and cooling time (t c ) were considered at four different values. The effect of the injection parameters studied has been analyzed through the quality and the shear stresses values of the injected and metallized PC/ABS specimens. Optical microscopic and confocal laser scanning microscope (CLSM) results demonstrate that the occurrence of some defects such as weld line, blister, poor adhesion, metal residue, sand scratch. Moreover, scanning electron microscope (SEM) findings show the presence of core defects and solidified pellets. Shear stresses vary between 3.78 and 5.8 MPa for the injected specimens and 4.5 and 6.4 MPa for the metallized specimens. The optimum injection parameter combinations were conditioned by producing flawless injected and metallized PC/ABS parts having a significant shear stress value. Thus, the optimum combinations consists of: a T ma of 260 C, a P inj ranging between 30 and 50 bar, a P h ranging between 20 and 25 bar, a T mo of 40 C, a t h ranging between 8 and 14 sec. and a t c of 25 sec. These findings may have interesting applications in automotive part industry.

“…4 представлены экспериментальные данные по двум типам образцов, напечатанным на 3D-принтере, и исходному материалу [6], не подвергавшемуся экструзии. В работе [6] изучалось поведение ABS-пластика при динамическом растяжении, экспериментальное исследование проводилось на установке РСГ. Хорошее совпадение прочности аддитивного и исходного материалов обусловлено тем, что толщина слоя печати равна 0.06 mm и печать проводилась перекрестно под 45 • к продольной оси.…”

“…Образцы изготавливались на 3D-принтере двух размеров с целью оценки возможности повышения скорости деформации за счет уменьшения рабочей части. Дополнительно проведено сравнение полученных результатов с прочностными данными исходного материала [6]. Полученные экспериментальные данные были описаны с использованием структурно-временного подхода.…”

Test results are presented for an additive material prepared of acrylonitrile-butadiene-styrene on a 3D printer. Dynamic tension experiments have been carried out using a tower-type drop hammer with an accelerator. Data obtained from different specimens demonstrate that high-strain-rate tensile experiments are feasible if the working part of the specimen is decreased. A theoretical analysis of test data using the incubation time criterion has been performed, and it has been found that analytical results are in good agreement with experimental data.

“…Generally speaking, there are three main methods to join the specimen and the bars in SHTB, screw, glue, or pin joint. For metal specimen, barspecimen joint by screw thread in SHTB is widely used [18][19][20][21], as shown in Fig. 1.…”
