Abstract Out-of-autoclave (OoA) prepreg materials and methods have gained acceptance
over the past decade because of the ability to produce autoclave-quality components under …

Composite materials have gained increased usage due to their unique characteristic of a
high-stiffness-to-weight ratio. High-performing composite materials are produced in the …

Optimization of process parameters of major aerospace composites manufacturing
techniques is essential for manufacturing high-quality aerospace components. However …

A short overview of main repair techniques for wind turbine blades and the related problems
of computational mechanics is presented. Computational models of the leading edge …

Fiber-reinforced polymer composites have excellent mechanical properties and outstanding
development potential and are cost-effective. They have increasingly been used in …

Fiber misalignment in composites in the form of in-plane waviness and out of-plane
wrinkling, is a major defect arising from processes such as hot drape forming. This work …

Out-of-autoclave prepregs based on woven fabrics initially consist of dry tows and resin-rich
areas. The tows allow air evacuation in the initial stages of processing and are subsequently …

The present study investigated the effects of three pressure-related process deviations
(reduced ambient pressure, reduced vacuum and restricted air evacuation) on the …

Tow impregnation as a function of material out-time was investigated for an out-of-autoclave
carbon fiber–epoxy prepreg. Prepreg was aged at ambient temperature for 56days. Every …

Curing aerospace composites is time-consuming with high energy requirements, particularly
when using methods such as autoclaves, ovens and heated presses. This study investigates …
