摘要:
A fiber-reinforced thermoplastic composite material comprising a fiber-reinforced thermoplastic core material is provided. In some embodiments, the thermoplastic core material has a maximum smoke density Ds (4 minutes) of less than 200 as measured in accordance with ASTM E662, a maximum heat release (5 minutes) of less than 65 kW/m2 as measured in accordance with FAA Heat release test FAR 25.853 (a) Appendix F, Part IV (OSU 65/65), and an average total heat release (2 minutes) of less than 65 kW/m2 as measured in accordance with FAA Heat release test FAR 25.853 (a) Appendix F, Part IV (OSU 65/65).
摘要:
A fiber-reinforced thermoplastic composite material having an advantageous combination of smoke generation, heat release, and mechanical property characteristics. The composite generally comprises a fiber-reinforced thermoplastic core containing discontinuous reinforcing fibers bonded together with one or more thermoplastic resins. The core material may further comprise at least one first skin material applied to a first surface of the core and/or one or more second skin material applied to a second surface of the core material. The thermoplastic core material has a maximum smoke density Ds (4 minutes) of less than 200 as measured in accordance with ASTM E662, a maximum heat release (5 minutes) of less than 65 kW/m2 as measured in accordance with FAA Heat release test FAR 25.853 (a) Appendix F, Part IV (OSU 65/65), and an average total heat release (2 minutes) of less than 65 kW/m2 as measured in accordance with FAA Heat release test FAR 25.853 (a) Appendix F, Part IV (OSU 65/65). The invention is useful in the manufacture of articles for aircraft, automotive, railcar, locomotive, bus, marine, aerospace and construction in which the certain advantages may be provided over other materials utilized for such applications.
