Negative mould fabrication

Negative mould fabricated by exposure to UV light through a photomask and developed in a developer solution... 

Since most self-reinforced polymer composite laminates described in literature are consolidated by thermal means, it is apparent that direct forming of composites in a final shape should also be feasible, if the shape is essentially a curved two-dimensimial structure without significant negative curvatures. The use of fabric reinforcement in different weave styles may dictate the complexity of the form, since difference weave styles are known to possess different drapabilities [235]. The use of male and female close-matched moulds should mean that processing of self-reinforced polymer composites based on technologies such as powder...
