Autoclave manufacturing of thick composites

Polymer Composites, 2002
AbstractAutoclave manufacturing of thermoset composites is determined mainly by heat transfer phenomena. As a matter of fact, the consolidation of composite laminates takes place by the progress of the polymerization, which is activated thermally.

Buckling of moderately thick composite plates

Composite Structures, 1991
Abstract In this paper an analysis of the buckling behaviour of anisotropic elastic plates is developed. The analysis is carried out by using a finite-element technique based on a shear-deformable plate model. Numerical results are also given relative to buckling of laminated plates under uniform axial compression, together with some comparisons ...

Analysis of Thick Laminated Composites

Journal of Composite Materials, 1990
This work focused on the analysis of laminated composite structures with a thick cross section. This investigation involved both analytical and experimental work. An efficient finite element analysis was proposed for analyzing thick laminated composite structures. The major feature of the analysis was that each element in the analysis can ac commodate

PZT ‘composite’ ferroelectric thick films

Journal of the European Ceramic Society, 2002
Abstract Thick-films of lead zirconate titanate ceramic have been fabricated at low-temperature using a modified sol-gel/ceramic powder technology termed the composite technique. In this process, a ferroelectric powder is suspended in an organometallic solution of the same composition, which is deposited either on metallic or platinised silicon ...

Intelligent Processing of Thick Composites

1999
Abstract : Composites consolidation In various manufacturing processes has been studied from a unified point of view to develop a simulation model. As a result a master formulation is now available and can be tailored to each manufacturing process.

Fracture of thick laminated composites

Experimental Mechanics, 1986
The fracture of thick laminated graphite/epoxy composites has been the subject of an extensive research program. The program was divided into three major areas of investigation which included laminate thickness, laminate stacking sequence, and part-through surface flaws.

Design of Thick Composite Cylinders

Journal of Pressure Vessel Technology, 1988
A simple and efficient design method for thick composite cylinders is presented. Micromechanics and macromechanics are integrated by simple relations and the integrated micro and macromechanics approach has been adopted to enable the designers to instantly study the sensitivity of the micromechanical variables on the final design.

Thick Composite Plates Subjected to Lateral Loading

Journal of Applied Mechanics, 1987
An analytical solution for an orthotropic plate subjected to general lateral loading is presented. The solution uses a stress function approach to obtain the localized stresses and strains due to the loading by an axisymmetric rigid sphere. Plots of load versus local indentation are compared with experimental test data previously reported in the ...

Temperature distribution of thick thermoset composites

Modelling and Simulation in Materials Science and Engineering, 2004
The development of temperature distribution of thick polymeric matrix laminates during an autoclave vacuum bag process was measured and compared with numerically calculated results. The finite element formulation of the transient heat transfer problem was carried out for polymeric matrix composite materials from the heat transfer differential equations

Composite plates of variable thickness

Journal of Machinery Manufacture and Reliability, 2010
A three-dimensional static model of an elastic-plastic body is considered with accounting for the dependence of the material characteristics on the temperature. The influence of the minimal and maximal plate thicknesses and the heat source power on the bending value and temperature is studied in order to reveal the cases of heating when in the ...
