Composites at a Glance

Material and Process Development for:

–Long fiber reinforced thermoplastics,

e.g. LFT direct process (LFT-D/ILC)

–Advanced LFT – use of engineering

thermoplastics as matrix polymer

in the LFT-D/ILC process

–Tailored LFT – co-molding of LFT with

local continuous fiber reinforcement

(Tailored Fiber Placement)

–Processing of thermoset composites and

process development for thermoset materials

e.g. SMC

–Development of natural fiber reinforced

composites in combination with biopolymers

–Plastic-metal-hybrid – compression molded

long fiber reinforced parts with metal inserts

for joining of metal and polymer components

–Component and process simulation for

LFT-parts and structures

–Cast-Polyamide – in-situ-polymerization

for the production of fiber reinforced high

performance parts

Direct Process for

Long Fiber Reinforced Thermoplastics (LFT)

LFT Direct Process (LFT-D)

Production of glass fiber reinforced thermoplastic parts with fiber direct incorporation: Direct incorporation of reinforcement fibers into the polymer resin melt and succeeding molding of the component parts

–Development of component-specific material compositions and properties –Adjustable fiber content and free choice of reinforcement type

Advantages

–Reduced production costs by the elimination of semi-finished products and logistical effort –Increased production flexibility –LFT-strand with variable thickness for optimized mold fill

LFT-D with In-Line Compounding (LFT-D/ILC)–Versatility regarding material composition –Just-in-time production

–In-line compounding of polymers and additives

–Use of engineering polymers –significant increase of properties
