In automated fiber placement (AFP), knowledge about the interaction between material properties and process parameters is essential to achieve cost-efficient manufacturing. Both, lay-up rate and defects are dependent on the properties of the uncured prepreg tapes which are out-time dependent. However, information thereof is not given in data sheets...

During the production process of some copper clad laminate (CCL), the content of 3,3,5,7,7-pentamethyl-1,2,4-trioxepane in prepreg can affect the cross-linking and curing degree of resin directly, and thereby affect the properties of CCL. In this article, near-infrared (NIR) spectroscopy combined with partial least square regression using high perf...

Three-dimensional (3D) printing of continuous fiber-reinforced composites has been developed in recent decades as an alternative means to handle complex structures with excellent design flexibility and without mold forming. Although 3D printing has been increasingly used in the manufacturing industry, there is still room for the development of theo...

Aerospace-grade composite parts can be manufactured using Vacuum Bag Only prepregs through an accurate process design. Quality in the desired part can be realized by following process modeling, process optimization, and validation, which strongly depend on a primary and systematic material characterization methodology of the prepreg system and mate...

Six matrices based on alkali-activated aluminosilicate with different amounts of potassium phosphate were prepared for the production of six-layer composite plates. The addition of potassium phosphate in the matrix was 2 wt%, 4 wt%, 6 wt%, 8 wt% and 10 wt% of its total weight. The matrix without the potassium phosphate was also prepared. The aim of...

The results of the study of experimental carbon fiber reinforced plastics based on a thermoreactive PMR polyimide binder are presented. The studies of the thermal stability of the carbon fiber reinforced plastics are carried out and their elastic strength characteristics at temperatures up to 320°C are determined. The possibility in principle of pr...

Bakalářská práce pojednává o problematice kompozitních materiálů s polymerní termoplastickou matricí, srovnáváme jejich výhody a nevýhody oproti dnes stále ještě rozšířenějším kompozitům s reaktoplastickou matricí. V experimentální části se zaobíráme přípravou a následnou výrobou kompozitu s polyethylenovou matricí, kde volíme dvě různé výztuže, kr...

The curing kinetics can influence the final macroscopic properties, particularly the three-point bending of the fiber-reinforced composite materials. In this research, the curing kinetics of commercially available glass fiber/epoxy resin prepregs were studied by non-isothermal differential scanning calorimetry (DSC). The curing kinetic parameters w...

Phenolic resin glass fiber reinforced prepregs are highly suitable for airplane interior components due to their high fire resistance, high temperature performance, and low-density characteristics. Safran Cabin seeks to improve their storage of the phenolic resin prepreg during their manufacturing process. The issues the company faces are the occas...

A free-space microwave nondestructive testing and evaluation module is developed for the low-power, non-ionizing, contactless, and real-time characterization of doped composite thin-film materials in an industrial context. The instrumentation proposed is built up with a handled vector network analyzer interfaced with corrugated horn antennas to mea...
