Teijin develops extra-light automotive side-door module made of advanced multi-material composites; 35% weight reduction vs steel

Teijin Limited’s car composites area of expertise agencies has advanced a multi-fabric composite automobile door idea that continues required crash specifications whilst decreasing usual weight by means of 35% when compared to a conventional metallic door.

A prototype of this unique technique advanced at the same time via Teijin Composites Innovation Center (TCIC) and Continental Structural Plastics Holdings Corporation (CSP), will be on show in the Teijin Group sales space at JEC World 2019, taking region 12 to fourteen March in Paris.

The module is crafted from carbon fiber sheet molded compound (SMC), glass fiber SMC and unidirectional glass fiber bolstered plastics (GFRP) to provide each excessive energy and occasional weight.

Additional benefits include value performance identical to that of an aluminum door module, and the capability to gain deep attracts and superior layout freedom now not manageable with a metal. The answer also withstands the warmth level of the traditional E-coat automobile portray technique.

Tough, lightweight, green modules are increasingly being followed, especially in Europe, for car components such as resin-based totally tailgates, bonnets (hoods) and roofs to help reduce CO2 emissions and further the variety of electric automobiles.

Multi-cloth facet-door modules for high-quantity automobiles have been found out by using some automakers, however, they nevertheless are in particular hard for designers as those additives have to meet mainly annoying necessities for surprise absorption to shield passengers in crashes, fatigue resistance to withstand the stresses of repeated establishing and last and accommodate indoors harnesses for electrical wiring and signal components.Teijin plans to hold improving the high-quality of its aspect-door module abilities by making use of diverse excessive-performance substances and technology available within the Teijin Group.

Leveraging its strengths in composite technology, the intention is to release a commercial door module by 2025 and grow to be known as a global dealer of multi-material automobile additives, targeting sales well worth about $2 billion by using 2030.

Continental Structural Plastics, a Teijin Group enterprise, has supplied leading-edge technologies in lightweight materials and composite solutions for the car, heavy truck, HVAC and production industries for 50 years.

Headquartered in Auburn Hills, Michigan, CSP offers full-service engineering support and holds multiple patents protecting materials development and production approaches in composite materials system, layout, and manufacturing technology. The enterprise has operations on three continents and greater than 4,200 employees.
