Conference Proceedings
Commercial Applications of Bio-Based Polymers in Automotive
PowerPoint Presentation at Automotive Composites Conference and Exhibition
Fire Resistance Cellulosic Fiber-Thermoset Composites
This presentation reports an innovative and sustainable approach to fiber surface treatment that improves the fire resistance of cellulosic fiber/ epoxy composites made with flax fiber. This new approach not only retards burning of cellulosic fiber but also produces self-extinguishing cellulosic-fiber composites. The low-cost treatment was carried out in aqueous solutions using non-toxic inorganic chemicals
Additive Manufacturing Research Briefing
This presentation will summarize Oak Ridge National Laboratory’s (ORNL’s) research activities related to additive manufacturing (AM). ORNL’s Manufacturing Demonstration Facility is exploring the use and further development of a wide range of AM technologies with basic research tasks focused on 1) new material development 2) in-situ process monitoring and control and 3) expansion of system capabilities. Use of AM across various industries will be highlighted as well as how ORNL is developing new technology in this space.
Machining Composite: A Collaborative Approach to Application Specific Solutions
This presentation discusses the difficulties that Lockheed Aerospace experienced routing composites for the F-35 fighter and how they overcame those challenges through a collaborative effort.
Recycling of Landfill-Bound Automotive Headliners into Useful Composite Panels
This paper describes the recycling of automotive headliner postindustrial waste into useful composite panels. The process relies on granulating the waste blending it with a 100% solids VOC-free MDI isocyanate adhesive and thermally molding the mixture under pressure using atmospheric moisture as the curing agent.
Development of PCM (Prepreg Compression Molding) Technology

Process and Equipment Breakthroughs in Long-Fiber Injection (LFI) Technology
PowerPoint Presentation at Automotive Composites Conference and Exhibition
Rapid Molding of Thermoplastic Composites
Rapid Molding of Thermoplastic Composites A crude bench-top setup was used to demonstrate a rapid resin transfer molding (RTM) process to make plaques roughly 25 cm wide 40 cm long and 0.5 cm thick from cyclic polybutylene terephthalate (cPBT). A 14 minute cycle was demonstrated. The cycle time included a 7 minute heating period used to increase the 150C de-molding temperature to the cure temperature of 230C in the forced hot air oven. The plaques demonstrated cure completion and molecular weight build consistent with commercial grades of PBT
Continuing the Development of Reduced Density Composites (SMC) for Automotive Applications

Eco-Friendly Automotive Plastic Seat Design
This paper deals with plastic front and rear seat designs that provide more than 20% weight reduction for improved fuel efficiency and lower CO2 emissions. The materials of construction include recyclable plastics and “green” polyurethane foam making this design eco-friendly. Low cycle time reduced part count and assembly time optimized contours for passenger comfort and reduced material consumption lead to cost-competitive design.
LIGHTWEIGHT DESIGN OF STRUCTURAL PARTS WITH THERMOPLASTIC COMPOSITES
Glass mat thermoplastic (GMT) composites have been available for many decades. Recent developments in woven-fabric reinforced GMT as well as improved computer simulations have enabled the material to be used in new applications that previously were designed solely in steel. This presentation will focus on utilizing computer simulations and best design practices in order to specify the most appropriate GMT formulation for a given application.
Processing Novel Braided Preforms of Carbon & PPS Thermoplastic Tape for Aviation & Automotive Seat Frames
PowerPoint Presentation at Automotive Composites Conference and Exhibition
Multi-Axial Assessment Method for Fatigue Calculations in Composite Components
Multiaxial assessment methods have proved to be a useful tool in the fatigue analysis of metallic components. Fatigue analysis of composites presents additional challenges due to the anisotropy and non-homogeneity of the materials. This presentation considers how multiaxial assessment methods may be extended and applied for fatigue analysis of fibre- reinforced composite materials.
Advancing structural capability of injection molded components with Continuous Fiber Reinforcement
This presentation provides a state-of-the-art overview on continuous fiber reinforcement laminates and tapes as overmolded inserts for enhancing structural capability of injection molded polyamide. The talk will highlight the design and manufacturing development of the world’s first seat pan made from a thermoplastic laminate with continuous fiber reinforcement.
High Density Polyethylene-Exfoliated Graphene Nanoplatelet Nanocomposites for Automotive Fuel Line and Fuel Tanks Applications
The potential of exfoliated graphene nanoplatelets (GnP) to increase the barrier properties of high-density polyethylene (HDPE) to oxygen and fuel was assessed. The mechanical properties (tensile flexural impact resistance) thermal stability and electro-conductivity of GnP-HDPE composites were studied as well. Those properties were related to the properties of the platelets (size aspect ratio) and the quality of their dispersion in the HDPE matrix
The Effects of Injection Molding Process Parameters on Final Fiber Length of a Short-Fiber Composite
Structural Thermoplastic Composites (STPC)
Continuous glass fiber-reinforced structural thermoplastic composites can be made with reactive resin systems using structural molding process such as resin transfer molding. By tailoring glass sizing chemistry composite properties can be improved significantly through maximizing the bonding between reinforcing fiber and resin matrix .
A FORMULATION STUDY OF LONG FIBER THERMOPLASTIC POLYPROPYLENE (PART3): MECHANICAL PROPERTIES OF PP DLFT COMPOSITES
PowerPoint Presentation at Automotive Composites Conference and Exhibition
Industrial Preformers for CFRP
Glass carbon aramid and natural fibers of every type and consistency can be successfully handled and precisely placed in large or small molds and formed into a preform in dozens of different applications. In each application the preform is then placed into a mold for the application/ injection of a thermoset resin to complete a composite part. The production equipment required to ensure a fast cycle time and a high quality part is described along with important considerations for the equipment.
