In addition, the interfacial adhesion properties of the PBO fiber reinforced epoxy composites were studied by microbond pull-out tests. It replaces the multiple user names and passwords necessary to access subscription-based content with a single user name and password that can be entered once per session. Citing articles are presented as examples only.
Here, F is the pull-out load, D is the diameter of the fiber, and L is the embedded length. The microbond specimens were pulled by MTS tensile testing machine at room temperature at a crosshead speed of 0.

Each monofilament sample was mounted across a cardboard sample frame using a room temperature curing adhesive according to ASTM D It operates independently of a user’s location or IP address.
Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as d339-75 as raw conversions to equivalent units.
Surface modification of PBO fiber by electrostatic discharge for composites. No chemical discharge was involved.

In addition, dd3379-75 unidirectional PBO fiber reinforced epoxy model composites were prepared from fiber strands. You either do not have a subscription or your subscription has expired. Sign in or create your free personal ASME account.
The cured epoxy was then debonded in shear from PBO fiber by the jaws of a microvice. The surface free energy was quantified using a dynamic contact angle analysis system.
The corresponding tensile strength properties of the fiber samples were analyzed by MTS tensile testing machine at room temperature.

In addition, differential scanning calorimetry DSC and X-ray diffraction XRD studies were also conducted to measure changes in thermal and crystalline behavior. We advise that atsm only use the original value or one of its raw conversions in your calculations to minimize rounding error.
Neat LDPE filaments were also extruded as control samples. In this paper, the effects of surface treatment on the modification of PBO fiber and its composite materials have been investigated using electrostatic discharge under atmospheric pressure. The distance between the discharge electrode and the samples was about 1.

These samples were fractured to reveal the interfacial adhesion bonding quality by the examination using scanning electron microscopy. All you need to read in the other general jounals BMJ ; MatWeb is intended for personal, non-commercial use. Two different operating voltages were studied at room temperature and atmospheric pressure: Please click here if you are a supplier and would like information on how to add your listing to this material.
The effects of electrostatic discharge modification on d379-75 interfacial adhesion asrm between PBO fiber and epoxy matrix were studied by microbond pull-out tests.
