TORAY NEW AMS SPECIFICATION FOR CMA 3900 PREPREG SYSTEM
March 16, 2021
New family of structural prepregs with extensive public allowable design database.
Tacoma, WA, March 16, 2021 - Toray Composite Materials America, Inc. (CMA) is excited to announce that a new family of structural prepregs are now available with an extensive public allowable design database. The SAE materials committee created a new AMS spec (AMS6891) specifically for Toray’s 3900-2 unidirectional and fabric products, these materials can now be procured and certified to the AMS 6891 specification. Five batches of 3900 allowable design data will be published in the next revision of the CMH17 handbook. The allowable test plan and datasets were created in accordance with FAA requirements and are intended for use in the design and certification of commercial, space, and defense primary structural applications.
Toray’s 3900 material system has enabled a step-function change in
the design of transportation systems by replacing metallic structures with
composite materials. The transformation to composite materials significantly
reduces structural weights enabling longer range, improved lifecycle costs, and
lower carbon emissions than legacy metal designs.
The 3900 system expands Toray’s product offerings with readily
available allowable datasets, the Toray 2510 out of autoclave prepreg system is
also available with existing AMS specifications and has a 3-batch allowable
dataset generated by the NIAR/NASA/AGATE consortium. Toray is committed to providing a full range
of products with publicly available allowable datasets, and is now working to
generate an extensive 5 batch dataset with a next generation T1100/3960 prepreg
