Pultrusion is an important process for the manufacture of thermosetting composites profiles of constant cross section. This work has shown experimentally and analytically the advantages of preheating the precursors to increase the line speed. The work was extended to quantify for the first time the duty cycle of a typical process. Heat transfer equations have been formulated to establish the temperature...
This work uses FE Analysis supported by experiment to establish the uniformity of mould heating in rotational moulding by the use of electrical heating elements placed in direct contact with the mould surface. This study is part of a larger project run by the Manufacturing and Management Group in The University of Manchester known as CHARM (Contact Heating Applied to Rotational Moulding), and which...
