Composite Materials for Rocket Vehicles

Use of Composite Materials in Public Service Vehicles

FEUP and INEGI are presently involved in relevant projects in the field of land transportation. An overview of the projects will be presented, focusing on the main results and the prospective to a near future. Public service vehicles (PSV) play a major role in the transportation industry of both industrialized and developing countries. Although the share of passenger transportation in PSV is re...

Properties of Composite Materials

strength, flexural modulus, and contraction stress of one orthodontic composite and two flowable composites. Orthodontic brackets were bonded to 45 human maxillary premolars with the composites Transbond XT, Filtek Z-350 flow and Opallis flow and tested for shear bond strength. For measurement of flexural strength and flexural modulus, specimens were fabricated and tested under flexion. For the...

Dielectric breakdown model for composite materials.

This paper addresses the problem of dielectric breakdown in composite materials. The dielectric breakdown model was generalized to describe dielectric breakdown patterns in conductor-loaded composites. Conducting particles are distributed at random in the insulating matrix, and the dielectric breakdown propagates according to new rules to take into account electrical properties and particle siz...
