this work investigates the feasibility of using recycled high density polyethylene (rhdpe), recycled polypropylene (rpp) and old newsprint fiber (onp) to manufacture fiber reinforced composites. the boards were made through air-forming and hot press. the effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...
The Beddington Trail/Centre Street, Calgary, Alberta, Canada, is the first prestressed concrete highway bridge built in Canada pretensioned by Carbon Fiber Reinforced Plastic, FRP, tendons. It is also the first bridge which has utilized a structurally integrated optical sensors system to monitor the behaviour. The bridge is completed and was opened to traffic on November 5, 1993. The project in...
A plasticity-fracture constitutive model is presented for prediction of the behavior of confined plain concrete. A three-parameter yield surface is used to define the elastic limit. Volumetric plastic strain is defined as hardening parameter, which together with a nonlinear plastic potential forms a non-associated flow rule. The use of non-associated flow rule improves the prediction of the dil...
Ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(PAN)-based carbon fiber. The surface characteristics of carbon fibers were characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber reinforced polyamide 6 (CF/PA6) composites were investigated by means of the single fiber pull-out tests. As a result...
Resin transfer molding of an inorganic polymer binder was successfully demonstrated in the preparation of ceramic fiber reinforced engine exhaust valves. Unfortunately, in the preliminary processing trials, the resulting composite valves were too brittle for in-engine evaluation. To address this limited toughness, the effectiveness of a modified fiber-matrix interface is investigated through th...

The HEPHAISTOS system integrates advantageously the basic processing steps as tooling, tempering of the resin and lay up, the impregnation of the fibers, pre-forming techniques as well as finally the process curing of the composite structures. Composites for aerospace applications in prepreg and wet technology have been successfully fabricated and investigated for quality and certification issu...
