Plastics — Preparation of glass fibre reinforced, resin bonded, low-pressure laminated plates or panels for test purposes

Specification of standard procedures for the preparation of test plates for subsequent preparation of test specimens by bonding glass cloth or mats with low pressure thermosetting resins. Three methods are specified: Method A: Glass reinforcement and liquid resin with suitable catalyst or curing agent are moulded in a press mould under appropriate conditions. Method B: Glass reinforced prepregs are moulded in a press at a mould temperature higher than room temperature. Method C: The glass reinforcement is manually laminated with simultaneous impregnation with a resin containing a suitable catalyst or curing agent.
