3 Days (SQ)RTM training for Engineers & Technicians
Coexpair proposes a 3 days general introduction to RTM for Aerospace. It covers the process, the design, the materials and the equipment used. 2 parts are fabricated by the participants to illustrate the theory & provide hands-on learning (see I hereunder). Following attendants expertise and interest the program is tuned. The discovery of the SQRTM process by the manufacturing of one part is proposed as an option.
Program
- 01- Introduction to aerospace composite processes. RTM & SQRTM state of the art.
- 02 – Illustrated presentation of the RTM and SQRTM processes.
- 03 - Practice in the shop: NC ply cutting and vacuum heat debulk. «Bulk factor » measurement. Mould preparation.
- 04 - Aerospace resin with their respective application (epoxy, BMI, etc…). Links between resin chemistry, mechanical properties and process.
- 05 - Aerospace reinforcement fibers (glass, aramide, carbon). Commercial denomination, architecture, mechanical performances & applications. Link between fiber surface & resin chemistry.
- 06 – Injection system. Presentation of different equipment (pressure controlled, flow controlled, pail un-loader, pressure pot). Pro & Cons. Risks and safety.
- 08 – Preforms for RTM: fabrics, braids, 3D. Usage and performances.
- 09 - Practice in the shop: First part: process understanding & spring-in effect illustration
- 10 - Lay-out of a typical RTM shop, from the stock of raw materials to the parts delivery.
- 11 - Practice in the shop: First part de-molding.
- 12 – Introduction to composite design & recommendations for RTM part design.
- 13 – Practice in the shop: Second part: a more complex preforming activity for a typical multi-cells part with removable mandrels
Location
This training is given at Coexpair in Belgium using Coexpair industrial equipment. Typical group size is 4-6 people.
