Abstract

THE INVENTION PROVIDES A METHOD OF MOULDING A REINFORCED STRUCTURE FOR USE IN A SUBSEQUENT MOULDING OPERATION TO FORM A MOULDED ARTICLE, COMPRISING THE STEPS OF HEATING A FIBROUS MAT (10) FORMED FROM FIBRES HELD TOGETHER BY A THERMOFORMABLE BINDER WHILE BETWEEN THE PARTS (11) AND (12) OF A MOULD TOOL, WHICH PARTS (11) AND (12) ARE PRE-COATED WITH A RELEASE AGENT; BRINGING THE PARTS OF THE MOULD TOGETHER USING A VACUUM WITH THE MAT (10) BETWEEN THEM; ALLOWING THE MOULD TOOL, WITH THE FIBROUS MAT (10) THEREIN TO COOL AND REMOVING THE MOULDED REINFORCING STRUCTURE THUS FORMED FROM THE MOULD TOOL. THE PARTS (11) AND (12) OF THE MOULD ARE BROUGHT TOGETHER BY PLACING THEM IN A VACUUM FORMING TABLE (14) AND THEN EVACUATING THE VOLUME ENCLOSED BETWEEN THE SHEET (10) SPANNING THE FRAME (15) AND THE LOWER PART (13) OF THE TABLE (14) WHEN BOTH ARE BROUGHT INTO CONTACT. ( FIG. 3 & 4 )
