Modelling shape distortions in composite products
نویسنده
چکیده
Woven fabric reinforced composite materials are typically applied in plate or shell structures, such as ribs, stiffeners and skins. Products of this type can be manufactured with several processes. A few examples are compression moulding, diaphragm forming, matched metal die forming and Rubber Press Forming (RPF). Shape distortions can occur during manufacturing of composite products. During the development stage of the products these distortions often exceed the required dimensional accuracy in the aeronautical and car industry. Accounting for the occurring distortions by adapting the mould shape can meet the demanded dimensional accuracy. This procedure is based on costly trial and error methods. Development costs can be reduced by modelling the shape distortions on beforehand and subsequently adapting the mould shape.

Kinetic Study and Modelling of n-Heptane Reforming Process over Pt/Zr-HMS/HZSM-5 Composite Catalysts
Pt/Zr(x)-HMS/HZSM-5 catalysts with various Si/Zr ratios (as x) were used for investigation of the kinetics of n-heptane reforming process under 350 - 450 oC reaction temperature, 35 to 80 ml min-1 flowing rate of hydrogen and 2 to 5 ml h-1 flowing rate of n-heptane. In the present work, two kinetics (power law and Langmuir - Hinshelwood) models were selected and examined to describe the kinetic...

INTRODUCTION Woven textile structures are often used as reinforcements in composite materials. Their ease of handling, low fabrication cost, good stability, balanced properties, and excellent formability make the use of Woven Fabrics (WF) very attractive for structural applications in, for example, the automotive and aerospace industry. However, due to the process of draping the fibre orientati...
متن کاملA Modelling Approach for Predicting Residual Stresses and Distortions in Polymer Composites
High dimensional variability is inherent in the manufacture of fibre-reinforced composite components. In the aerospace industry, this stems largely from the elevated temperatures needed to process the composite materials, which give rise to residual, or frozen-in, stresses; these are exacerbated by chemical shrinkage of the resin during cure. These stresses can subsequently cause distortion and...
