Manufacturing of Fiber Reinforced Thermoplastic Composites from Microwave Active, Nanomodified Hybrid Yarns
In order to achieve efficient lightweight structures while staying profitable, fiber reinforced thermoplastic composites (FRTCs) are being developed. Considering the production process, the heating and cooling times of these organic sheets are the cycle-time determining factors.
Shorter cycle times lead to higher outputs, thus reducing the costs per part. To achieve a reduction of heating times, microwave active hybrid yarns containing nanomodified polypropylene-filaments are produced and examined at the Institute for Textile Technology Aachen (ITA). The focus of this illustration lies on displaying the achievable heating times of microwave active materials.

Assessment of Laminae Indentation Pressure of Spiral Wrap versus a Planar Distribution Medium in VIP
The use of spiral wrap tubing as a means to distribute resin and/or provide vacuum distribution in the vacuum infusion process has long been common practice. However, the round profile of the spiral wrap tubing causes mark-off, aka indentation, in the underlying laminae, resulting in variation in the laminate fiber volume, weakening the part.
A new planar profile resin/vacuum distribution medium, designed to distribute the localized pressure for reduced mark-off, has been developed as an alternative to spiral wrap tubing. This poster presents the results of topographical pressure mapping of spiral-wrap tubing versus the new planar profile medium.

Application of Polyetherimide in Automotive Body Parts with
High-class Surface and Thermal Stress
This work highlights important findings on the suitability of composites consisting of the amorphous thermoplastic polyetherimide (PEI) and carbon for automotive body parts with high-class surface and thermal stress. In detail, technical merits and demerits of the composite structure are pointed out on the basis of optical, but also mechanical and thermal tests. An automotive body part from the automotive industry with a class-A surface serves as a benchmark. Furthermore, most important economic aspects of a serial production of PEI/CF composites for automotive applications derived from a process cost analysis are displayed.

New Sizings for Glass Fibers for the Use in Thermoplastic
Lightweight Material - HiPer Sizing
The project HiPer Sizing shows that the development and upscaling of a bio-inspired multifunctional sizing, its application to glass fibers for both, single filament glass fibers as well as multi-filament rovings, the characterization and processing of these fibers into fabrics and

POSTER SESSION finally components is a challenging but solvable issue. New synthetic strategies for the integration of catechol segments in sizings have been developed and tested for their scalability for application on an industrial scale. The main part of the project was the up-scaling from laboratory scale above sizing of single filaments up to apply sizing on a pilot scale.

Carbon Nanotube Fiber Composites for Simultaneous Structural
Health Monitoring and Strengthening of Steel Structures
Fiber composites have been extensively researched as a potential candidate for strengthening of steel structures and have been recently used in field applications. While these structures are under rehabilitation, it is critical to continuously monitor the structural health and the effectiveness of the fiber composite applied. We propose a unique solution where piezo-resistive carbon nanotube sensing layers are integrated with structural carbon fiber composites capable of concurrent structural health monitoring and strengthening of steel structures. This poster describes the fabrication of this novel composite and demonstrates its sensing response along with improved mechanical properties.

REWIND: The Way From Wind Rotor Scrap to Valuable Material
Aim of this Poster is to present the results of the public founded project
REWIND. Parts of an old wind blade have been shredded by a universal shredding machine and transformed in a valuable material. After that the fibers have been separated from the matrix using a thermal treatment that completely transformed the epoxy resin into gases and oil. The recovered fibers have been processed in a non-woven and finally in a new FRP.

Thermal and Mechanical Performance of Low Density Materials
Multifunctional composites have garnered much attention due to the enticing prospect of achieving multiple functions or engineering goals in a single, well designed material. Interest has recently developed for low density, high strength composites which are also excellent thermal insulators. Although aerogels are considered the state-ofthe-art thermal insulation materials, they are in most cases extremely brittle. Multifunctional polymers developed at the CAPE Lab at SDSMT demonstrate high thermal insulation capability and also achieve higher strength than their aerogel counterparts. Applications for these types of multifunctional composites range from outer space vehicles and habitats, to terrestrial clothing and food storage containers.

Microstructural Investigation of Commercially Available Pristine
Composite Bars for Concrete Reinforcement
This Poster presents the result of scanning electron microscopy (SEM) imaging on four different commercially available pristine glass fiber reinforced polymer (GFRP) bars. It captures the: (I) existing crack/ void patterns in the matrix, (II) fiber/matrix interface and (III) fiber distribution in the matrix. Moreover, panorama images of the entire cross sections are provided to give a proper comparison between different bars. Considering lack of a GFRP microstructure notation in the literature, these results can be used as a benchmark for microstructure of commercially available pristine GFRP bars and serve as a base for monitoring possible changes after any experiment.

Identifying the Strain-Free Condition of Non-Symmetric Carbon
Fiber Laminates Using Digital Image Correlation
Processing carbon fiber composite laminates creates molecularlevel strains in the thermoset matrix upon curing and cooling which can lead to shape deformations, micro-cracking, and other issues.
Non-symmetric [0x/90x] laminates are often used to demonstrate the presence of residual strains, wherein laminate curvature is indicative of the strain magnitudes. In this study, 16 ply [0x/90x] laminates were fabricated using a commercially-available prepreg and cured per the manufacturer’s recommended cure cycle. Digital Image Correlation was used to observe curvature compensation by thermal means, with the aim to demonstrate its potential as a highly-sensitive technique for probing residual strain levels in composite laminates.

Method to Reduce Costs for Production of PAN Based Carbon
Fibres
Carbon fibres feature excellent mechanical properties combined with low density. However, carbon fibres still have a low market. The bottleneck during production is the stabilization with process times up to 2 hours and temperatures of up to 300 °C. Industrially the stabilization is carried out in 4 to 6 different ovens with increasing temperature and equal residence time. Through a DSC analysis of the exothermic reactions it can be shown, that the residence times in the first ovens can be reduced by 50 % to 15 min. The strength of the carbonized samples is equal to a Toho Tenax HTS40.

Carbon Fiber Reinforced Cyanate Ester Nanocomposites:
Thermal, Mechanical and Electrical Characterization
The intent of this research is to observe the response of low loadings of multi-wall carbon nanotubes on Carbon Fiber Reinforced Cyanate Ester
Nanocomposites . More specifically, mechanical (tensile, shear, flexure, and compression), thermal stability (decomposition), and flammability
(heat capacity and heat release rate) properties were analyzed. Our objective was to use MWCNT to enhance CE resin so that composites manufactured from it may hold comparable flammability and thermal stability properties to the industry popular resins, polyimide. It was hypothesized that there will be no sacrifice in mechanical performance, which is vital in structural composites for high temperature applications.

The Effect of Flocculent, Dispersant Concentration on Wet-Laid
Process for Recycled Glass Fiber/ PA6 Composite
Wet laid process has traditionally been used in paper making and textile industries. Recently this process finds applications in composite industries. Wet laid process is very simple and it reduces a lot of processing and manufacturing cost. Since the process involves only pulp formation, the fiber attrition is minimal. Also wet laid is an effective way to use recycled fibers.
