2700 Prepreg System
Data Sheet
PRODUCT NOTESThe 2700 prepreg system is specifically formulated for heat resistance and low water absorption which makes it suited forapplications where it is exposed to high heat and high humidity environments. It is a rapid cure system that enables parts tobe cured in a press mold in five minutes at 300°F (149°C). 2700 has excellenct all-around properties and has low void content
and optimized tack. Customers using Toray’s 2510 and 2511 resin system may easily adopt 2700 with minimal impact on
their production environment. Applications include aerospace primary or secondary structure components and industrialapplications.
Flexible Cure Methods
Proven flexibility in curing and consistency inmechanical properties has been achieved by ovencure, autoclave, and compression molding.

High Heat Tolerance
High Tg and hot/wet performance enable retentionof critical properties like open-hole compression
to 180°F (82°C) without compromising material
toughness.

Resin Chemistry
Patented system features unmatched cure speed inaerospace epoxies while also minimizing exotherm
potential for thick laminates.

ToughenedHigh strength fiber is combined with particulate
toughening to reduce delamination and increase
fracture toughness, impact resistance, andenvironmental resistance.

Customizable Forms
Compatible with multiple applications, including
AFP, ATL, and hand layup. Multiple widths and rollconfigurations available.

Rate ReadySingle system seamlessly transitions from R&D toto Low Rate Initial Production (LRIP) to Full Rate
Production (FRP) with equivalent datasets enabling
go-to-market success.

PRODUCT SPECIFICATIONS

2700 has been tested using the following product forms, however final configurations are possible with numerous types ofTORAYCATM unidirectional carbon fibers and other woven carbon or glass fabrics with Fiber Areal Weight (FAW) ranging from70 g/m2 to 300 g/m2 and Resin Content, (Rc %) by weight percent, ranging from 24% to 46%.
