AB  - Engineered wood products along with advanced processing and fabrication are pushing the limits of modern wood construction. Innovative concepts and applications facilitate the development of a new generation of structural systems. However, capacities of such systems are often governed by capabilities of the connections. This paper presents the experimental results with numerical and analytical models of angle brackets for prediction of load bearing capacity, stiffness, and ductility.
Three types of metal brackets in beam-column connections have been investigated and their performance has been studied in various loading arrangements. Detailed finite-element models of each connection have been developed to gain insights into their behavior. An analytical approach is also adopted to represent the connections. Comparison with test data suggests that
the models can reproduce results with good accuracy. The findings confirm feasibility of implementing ductile connections in practical mass timber structures.

AB  - Kevlar fibers are widely used for industrial and military purposes due to their remarkable mechanical properties, such as their high tenacity and high strength-to-weight ratio. In this study, two-layered Kevlar composite specimens were impregnated with 10 wt.% poly (vinyl butyral)/ethanol solution which contained TiO2 nanoparticles as reinforcement. The concentrations of the nanoparticles were 1 wt.% or 2 wt.% with respect to the poly (vinyl butyral), PVB. The single-axial tensile test and three-point bending test of the Kevlar/PVB composites have been performed according to the ASTM D 3039 and ASTM D 790-03 standards, respectively. The tensile and bending properties of the dry and wet Kevlar/PVB composite specimens after a 56-day immersion are examined in this work. Upon the addition of the 2 wt.% TiO2 nanoparticles, the tensile strength and modulus of the dry specimens without reinforcement were increased by 39.8% and 24.3%, respectively. All the submerged specimens’ tensile and flexural property values were lower than those of the dry specimens. After comparing the wet composite specimens to their dry counterparts, the percentage decrease in tensile strength was approximately 20%. The wet Kevlar/PVB specimens with no TiO2 reinforcement showed the greatest reduction in bending strength, 61.4% less than for the dry Kevlar/PVB specimens, due to the degradation of the PVB matrix. In addition, a numerical simulation of the three-point bending test was carried out in Abaqus.

AB  - The Kevlar fabric composites have a wide range of applications in the
body armor and lightweight vehicle-armor structures. Nanoparticles are one of the
most common nanofillers for these structures. In this research, the testing specimens have been made from the Kevlar fabrics impregnated with the poly (vinyl
butyral)/ethanol solution which had been reinforced with the ZnO nanoparticles.
The two-layered composite samples have been fabricated by means of hot compression. The immersion of the square Kevlar/PVB specimens for the water uptake
measurements has been performed according to the ISO 62 standard. The specimens have been immersed in a water bath filled with the distilled water (40 °C) in
the period of 8 weeks. The Kevlar/PVB specimens have been tested in accordance
with the ASTM D 3039 standard for the tensile properties and the ASTM D 790–
03 standard for the flexural properties. The tensile and bending characteristics of
the dry specimens have been compared with the ones that had undergone the water
immersion.

AB  - In this research, the testing specimens were made from the Kevlar fabrics impregnated with 10
wt.% poly (vinyl butyral)/ethanol solution but with the addition of the TiO2 nanoparticles. The
tensile and bending properties of the dry specimens were compared with the ones that had been
immersed in a water bath filled with distilled water (40°C) in the period of 8 weeks.
The PVB/fabric weight ratio for the impregnation of the woven Kevlar fabric was 20 wt.%. The
Kevlar/PVB fabric composites were reinforced with the TiO2 nanoparticles in different
concentrations (1 wt.% or 2 wt.% of reinforcement regarding poly (vinyl butyral), PVB). The
two layers of composite fabrics were hot-pressed by using the digital press at a temperature of
170 °C for 30 minutes.
The immersion of the square Kevlar/PVB composite specimens for the water weight gain
measurements was performed according to the ISO 62 standard. The Kevlar/PVB specimens
were tested in accordance with the ASTM D 3039 standard for the tensile properties and ASTM
D 790-03 standard for the flexural properties.
During the tensile and the flexural test, the complete fracture of the specimens did not occur.
The addition of 2 wt.% TiO2 nanoparticles produced 39.8% and 24.3% improvement in the
tensile strength and tensile modulus, respectively, compared to the dry Kevlar/PVB specimens
without reinforcement. The tensile properties of all the immersed Kevlar/PVB composite
specimens had decreased values compared to the ones of their dry specimens.
Unlike the tensile test results, the best flexural properties (strength and modulus) were achieved
with the dry specimens with no particles due to the better bonding between their two
impregnated fabric layers since the presence of TiO2 nanoparticles reduced the shear
connection between the layers. However, there was not such a decline in the properties of the
wet specimens with nanoparticles which even made some improvement in the bending strength
compared to the wet Kevlar/PVB specimens.

AB  - The para-aramid fibres (Kevlar, Twaron, Kolon) are high performance polymeric fibres characterized by their high tenacity, strength to weight ratio and impact resistance. They are used for the soft body armour structures in ballistics and for the manufacture of parts in aerospace and automotive industry.
In this study, the specimens were made from the two-layered Kolon fabrics impregnated with epoxy resin where some silicon carbide (SiC) microparticles or SiC nanofibres were added as reinforcement. These composite specimens
were fabricated by hot compression and curing of epoxy resin.
Despite their good mechanical strength it is a well-known fact that the mechanical properties of epoxy resins are affected by moisture absorption. The tensile and impact properties of the untreated specimens were compared with the ones that underwent water absorption in the duration of 72h (immersion or humidity) followed by desorption. The immersion of the specimens in water and the exposure to high humidity (70%) were completed in accordance with the ISO 62 standard while the tensile test was performed according to the ASTM D 3039 standard. Furthermore, the tensile test simulation of the Kolon/epoxy composite by using software Abaqus® was accomplished.
For the determination of the absorbed impact energy and the impact toughness of the composite specimens, an impact test was performed by using the Charpy impact pendulum in accordance with the ASTM D5942 standard.
