Technical Guidance Information

01

Storage and Out Life

This material should be kept frozen at -18°C (0°F). It must be kept sealed in a polythene bag which must not be opened until fully thawed to room temperature. If the material is not fully used, then the material must be resealed in the polythene bag to prevent moisture absorption.

02

Health and Safety

This material contains epoxy resin which can cause allergic reactions with skin contact and must avoid repeated and prolonged skin contact.

Please refer to the product Safety Data Sheet before using this material. The following precautions must be taken when using epoxy resin prepregs:

  • Overalls must be worn

  • Impervious gloves must be worn

  • Curing schedule is meant to be as a guide only and is subject to local conditions

  • To avoid exotherm, particular care must be taken with thick laminates

  • Ramp rates must not exceed 3.0°C (5.4°F)/min during initial cure and 0.3°C (0.5°F)/min during post cure

Frequently Asked Questions

01

What prepreg is suitable for flame-retardant composite parts?

MTC510FRB is designed for parts that need both strong fire performance and reliable structural properties. It offers good surface quality, toughened epoxy performance and can achieve UL94 V0 in suitable laminate thicknesses. 

02

Does MTC510FRB meet aerospace fire standards?

Yes. MTC510FRB complies with FAR 25.853 requirements for 60-second vertical burn, smoke and toxic gas emissions, making it suitable for aerospace and other applications where fire safety is critical. 

03

Can flame-retardant prepreg still give a good surface finish?

Yes. MTC510FRB is designed to combine flame resistance with an excellent surface finish, making it useful for visible composite parts where both appearance and fire performance are important. 

04

Can MTC510FRB be used for battery boxes and fire containment?

Yes. SHD recommends MTC510FRB for battery box and fire-containment applications, particularly where a flame-retardant structural material is needed alongside tough, dependable epoxy-style processing. 

05

Can flame-retardant prepreg be supplied with different fibre types?

Yes. MTC510FRB can be supplied on a range of fabrics and in unidirectional form, allowing the reinforcement to be chosen around the part’s strength, weight, cost and manufacturing requirements.
