Two different operating voltages were dd3379-75 at room temperature and atmospheric pressure: Surface modification of PBO fiber by electrostatic discharge for composites. Questions or comments about MatWeb? The degree of surface modification increased with the applied discharge voltage.

The cured epoxy was then debonded in shear from PBO fiber by the jaws of a microvice.

It operates independently of a user’s location or IP address. The surface free energy of D33779-75 fiber was analyzed from the measured contact angles between each sample and five different liquid contact media, including n-hexadecane, dimethyl sulfoxide DMSOethylene glycol EGformamide and water.

We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. The Epon type epoxy was premixed with a hardener d33799-75 delivered to PBO fiber using a syringe. Some tools below are only available to our subscribers or users with an online account.

It seemed that a thin layer of oxidized substance has been deposited on the surface. The surface displayed some scars from the electrostatic treatment effects also discharge treatment. The fiber surface morphology was examined by scanning electron microscopy. The surface free energy was quantified using a dynamic contact angle analysis system.

CNTs were functionalized with OH functional groups using chemical treatment. In addition, the interfacial adhesion properties of the PBO fiber reinforced epoxy composites were studied by microbond pull-out tests. Here, F is the pull-out load, D is the diameter of the fiber, and L is the embedded length.
