Void Morphology in Polyethylene/Carbon Black Composites [PDF]

MRS Proceedings, 1996
ABSTRACTA combination of small angle neutron scattering (SANS) and contrast matching techniques is used to determine the size and quantity of voids incorporated during fabrication of polyethylene/carbon black composites. The analysis used to extract void morphology from SANS data is based on the three-phase model of microcrack determination via small ...

Determination of flow front velocity and optimal injection pressures for better impregnation of E-glass with polyester in resin transfer mold [PDF]

INCAS Bulletin, 2019
Flow front velocity of resin plays a key role in yielding better impregnation of fiber reinforcement in resin transfer molding to fabricate quality composites. A video camera was used to capture the patterns of resin flowing below the grid lines drawn on

Void Analysis as a Test for Dark Matter Composition? [PDF]

The Astrophysical Journal, 1996
We use the void probability function to compare the redshift--space galaxy distribution in the Perseus--Pisces survey with artificial samples from N-body simulations of standard cold dark matter (CDM) and broken scale invariance (BSI) models. Galaxies are identified as residing in peaks of the evolved density field in such a way as to reproduce both ...

Ultrasonic Detection of Voids in Ceramic Composites

NDT International, 1989
Ceramic composites are intended to take advantage of the high temperature capabilities of ceramics while minimizing the disadvantages caused by their very brittle nature. The particular material under study consists of a Nicalona fiber weave reinforcing fabric in a silicon carbide matrix formed by a chemical infiltration process [1].
