Project title: Development of automotive market fitted, CRTM manufacturing process. (ADVANCRTM)
Project number: 10032/14/22619/Ae
Runtime: 1/3/2016 – 27/2/2019

The quest to reduce C02 emission in transportation is highly dependent on lightweighting measures, as novel drive trains and energy storage method penalize car weight. The massive use of composites reinforced with carbon fiber reinforced polymers (CFRP) in cars and commercial vehicles is one of the most appropriate solutions, as they can reduce weight by up to 70% (= reduced consumption / emissions = increase autonomy) and the ability to dissipate impact energy is 5 times greater than that of metals.

One of the most promising alternatives to reduce fill times and increase the fiber content of CFRP is the process called Compression Resin Transfer Molding (CRTM).

 

 

The objective of ADVANCRTM is to generate expertise to design the molds and presses for advanced compression resin transfer molding (CRTM) process, with the potential to substantially reduce cycle time and costs tuning in the manufacture of high performance composites, and search of its physical and geometrical limits.

Consortium of ADVANCRTM project will yield in an optimized resin transfer molding process for large, complex structural parts for the automotive industries. Basic idea is to reduce the injection time for these large parts by lowering the compaction of the fibers (Compression) RTM and thus increasing the permeability of the used fabric. After, opening the mold by some millimeters and fill the occurring gap with resin, by compressing the mold the infiltration of the fabric will be in z-direction and therefore very short.

Overall goal of the technology is to fasten processes and make room for faster chemistry, shorter injection times, shorter reaction time and faster turnaround on the molds. The equipment resulting in an increase of efficiency will enable OEMs to integrate this efficient CFRP parts into lower price segmented cars, increasing the efficiency of standard transportation and helping reaching emission goals of the future.
