Y-Shaped Vent Tube | Complex Geometry Composite

Duncan Treen Case Studies

Previous Process The baseline process was to lay-up this aerospace grade, Y-shaped vent tube in two halves into the female cavity of the cure mold that were joined for cure. This frequently resulted in the laminate being pinched and uneven. It also forced the lap joints to be staggered over the same area, resulting in a thicker composite part with …

Alternative to Washout Tooling | Non-Structural Duct Case Study

Duncan Treen Case Studies

PROBLEM – Fabricate a non-structural duct in a quick, clean, and efficient process without an autoclave or washout tooling. OPPORTUNITY – Create an oven cure solution that will produce a high-quality composite duct with a reusable Smart Tool. SOLUTION – A Smart Tool that acts as a bladder during cure was combined with a OML cure mold to create an …

Trapped Geometry Demolding – Benefits of Smart Tooling

Duncan Treen Case Studies

One of the major benefits of Smart Tooling is the ability to demold from trapped geometry. In the video below, we demonstrate how Smart Tools that act as Bladders are rigid during cure, and elastic at extraction. This elasticity allows the Smart Tool to be extracted from a composite part with complex or trapped geometry. Once extracted, the Smart Tool …

Trailing Edge Control Surface WITHOUT The Use of Foam

Duncan Treen Case Studies

Smart Tooling uses exclusive shape memory polymer tooling technology to produce a composite multi-chamber trailing edge control surface with co-cured spars without the use of foam core. Traditionally, a composite trailing edge control surface required the use of foam fabricated to a knifepoint to mold the trailing edge because traditional tooling methods could not mold composite with such small, and …

Co-cured Composite Structures Using Smart Tooling

catapult Case Studies

How Smart Tooling can offer better quality, lower cost, and throughput advantages over traditional fabrication methods for co-cured composite structures. Using Smart Tools to Create Multi-Chamber Control Surfaces Using Smart Tools to create co-cured composite structures such as a multi-chamber control surface improves part quality by allowing the customer to lay-up on male tools. Traditional fabrications require layups to be …
