Veils for composites

The basalt fiber veil is stable up to 850°C and retains its integrity when in contact with an open flame.

Technical Fibre Products (TFP) plans to exhibit it range of nonwovens at the JEC Forum, talking place on 23 November in Frankfurt, Germany.

This includes a polyimide veil, reportedly is the highest temperature stable polymer veil that TFP manufactures, with a maximum service temperature of above 260°C –higher than other polymers such as polyester and polyphenylene sulfide (PPS). The material was developed as a insulation material for space applications, where it can offer the temperature stability necessary to withstand missions to Mercury and the Sun, TRP said.

The other new veil, made from basalt fiber, is stable up to 850°C and retains its integrity when in contact with an open flame, making it suitable for applications requiring a fire barrier, according to the company. Basalt, like glass, also has a high resistance to acid and alkali, which makes it suitable for use in corrosive environments.
