Tensile tests of the fibre specimens were measured using an Instron Tensile Tester fitted with a 5.00 N load cell. All tests were conducted at a fixed gauge length of 20.00 mm and at a controlled extension rate of 1.5 mm/min. The instrument was programmed to apply a pre-load of 0.10 cN before recording load-extension data. Tensile test measurements were repeated 5 times for each sample. The tensile stress of the fibres was calculated from dividing the load by the fibre cross section area, units in MPa. The cross sectional area was determine by means of an optical microscope. The Young’s modulus was obtained from measuring the gradient of the elastic region of the stress–strain curve, units in GPa. All samples were conditioned at 20 ± 2 °C and 65 ± 2% RH for 24 h prior to testing.

The Tensile Tester is a laboratory instrument used to measure the tensile properties of materials. It applies a controlled load or force to a test specimen and records the resulting deformation or elongation, providing data on the material's strength, stiffness, and other mechanical characteristics.

The surface morphology of the porous HDPE, HDPE/PEAA, and HDPE/PEAA/Col scaffolds was observed under a field emission scanning electron microscope (FE-SEM S4300; Hitachi, Japan) after sputter-coating with platinum. The chemical bonds and elemental composition were characterized by Fourier transform infrared (FT-IR; Mattson, Galaxy 7020A) spectroscopy and electron spectroscopy for chemical analysis (ESCA; ESCA LAB VIG microtech, Mt 500/1, and so forth, East Grinstead, UK), respectively.
Tensile properties were measured via a universal testing machine (Instron, model 4465) with a Zwick Roell tensile tester equipped with a 1 kgf load cell, at 25 °C with an extension speed of 10 mm/min. The tensile strength and Young’s modulus measure of each sample were calculated from the averages of 10 specimens.
The porosity of the porous scaffolds was determined by using a mercury intrusion porosimeter (AutoPore IV 9520; Micromeritics Co., USA). The advancing and retreating contact angles of mercury were taken to be 140° and the surface tension was taken as 0.480 N/m (480 dynes/cm).

To determine the tensile properties of the composites, an Instron tensile tester was used. The tensile characteristics of the composites were tested using the ASTM: D 638 standard at a crosshead speed of 5 mm/min23 (link). The flexural strength of the specimens was tested in accordance with ASTM D790-03 using a Kalpak Universal Testing Machine with a 20kN capacity and a crosshead speed of 2 mm per minute. For the impact test in this instance, specimens of the composite were cut out in line with ASTM: D25624 (link)–26 (link). For each test, three samples were examined, and the average outcomes were noted. The tensile, flexural, and impact. specimens are shown in Fig. 3 .![]()

cut with a gauge length of 6.25 mm and width of 1.5 mm and placed
into a tensile tester (Instron, Norwood, Massachusetts, USA) with
a 24 N load cell. A strain rate of 2 mm/min was applied to the samples
until failure. Young’s modulus, tensile strength, and maximum
strain at fracture were determined from the resulting stress/strain
curves.

The ultimate bursting strength and elongation at break were evaluated according to the standard ISO 7198:2016, “Cardiovascular Implants and Extracorporeal Systems”. A compression cage assembly was mounted on an Instron tensile tester, and each specimen was placed between two horizontal clamping plates. A puncture probe measuring 6 mm in diameter with a smooth spherical end was used to burst the scaffold specimens held horizontally. The load-extension curves were obtained with a 2 kN load cell and traverse speed of 300 mm per minute. We calculated the bursting strength in kPa and the percent elongation at break using the geometry described in Figure 2 .
According to the geometry, to calculate the linear elongation at break, the original length was considered to be 12 mm, which was the diameter of the open area where the specimen was held between the clamping plates. The extended length for each specimen was calculated from the Equation (2):
where r = 3 mm and x was the hypotenuse of the triangle ABC inFigure 2 , where the vertical distance y was read from the displacement measured during the test.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
