Fibers Microbuckling of Uncured Carbon-Epoxy Prepreg in Bending

Creator:: Guo, Yizhi
Abstract:: Prepreg is widely used in composite manufacturing with advanced composites such as carbon and aramid. The material is characterized by a degree of flexibility (drape) and stickiness (tack), which allows an efficient layup on molds with complex shapes. However, axial instability of compressed fibers during the molding process may occur,...

The effects of extractives and compatibilizers on the flexural properties of natural fiber-thermoplastic composites

Creator:: Saputra, Hartono A.
Abstract:: Natural fibers such as wood, flax, and hemp are frequently used as fillers in natural fiber-plastic composites (NFPCs). At present, wood fiber is the most commonly used filler in the production of wood-plastic composites (WPCs). The advantages of these fibers compared to conventional inorganic fibers such as glass fiber is...

Studies of polystyrene (PS) high density polyethylene (HDPE) and PS/HDPE/wood composites from an extrusion process : mechanical properties, rheological characterization and morphology

Creator:: Xu, Bin
Abstract:: The global motivation for this work comes from the desire to fabricate "plastic lumber" with improved mechanical properties (particularly creep resistance) from recycled plastics and wood composites. The present studies have utilized "virgin plastics" of polystyrene (PS), an amorphous, stiff material that exhibits brittle fracture, and high density polyethylene (HDPE),...

Ionic Cross-linked Cellulose Nanocrystals Composites of Poly(vinyl acetate)

Creator:: Chan, Han Ling
Abstract:: Understanding the effect on the materials mechanical properties from the perspective of interfacial interaction between the filler and the polymer matrix has become an important criterion in polymer nanocomposites field. Cellulose nanocrystals (CNCs) are renewable materials that can be extracted from natural sources, such as wood, cotton, and tunicates. In...

Copper compounds for durable composites : effects on material properties

Creator:: Vidrine, Cheney L.
Abstract:: The effects of incorporation of selected biocides on physical and mechanical properties of aspen strandboard were assessed using five copper-based preservatives or zinc borate at three retention levels. Tebuconazole or 4,5-dichloro-2-N-octyl-4-isothiazolin-3-one (DCOI) were added as co-biocides to selective copper-based treatments. Mold box tests showed that only panels treated with DCOI...

An experimental approach to analyze large notched composite panels loaded in out-of-plane shear

Creator:: Froemming, Tyler M.
Abstract:: Identifying material characteristics of composites is important in designing any structural system. The aerospace industry relies on these material properties not only to design a functional aircraft, but also a safe and reliable one. Since carbon fiber composites are relatively new materials, little is known about its characteristics under certain...

Application of digital image correlation in material parameter estimation and vibration analysis of carbon fiber composite and aluminum plates

Creator:: Chuang, Chih-Lan Jasmine
Abstract:: Identifying material parameters in composite plates is a necessary first step in a variety of structural applications. For example, understanding the material parameters of carbon fiber composite is important in investigating sensor and actuator placement on micro-air-vehicle wings for control and wing morphing purposes. Knowing the material parameters can also...

Investigation of Styrene-Free Unsaturated Polyester Resins for Fiber-Reinforced Composites

Creator:: Wu, Yili
Abstract:: Most of existing commercial unsaturated polyester (UPE) resins are typically composed of a UPE and a high amount of highly volatile, flammable, and toxic styrene. The emission of hazardous styrene in the handling of the UPE resins and the preparation and use of fiber-reinforced UPE composites poses severe hazards to...

Failure analysis of pre-notched composite laminated plates under four-point bending conditions

Creator:: Arias Gonzales, Sergio
Abstract:: Ever since composite laminate technology was introduced into the aerospace and automotive industry, there has been a need to fully understand the damage progression experienced by composite laminated plates in the presence of a notch. While numerous research studies have been conducted on this matter when subjected to in-plane loads,...
