“…Furthermore, as fiber/ matrix interactions are of the frictional type, transverse load is more prone to creep as it relies purely on tensile decoupling of the fiber/matrix interface. The n parameter was found to decrease with the angle but this is not necessarily related to any particular characteristic of the material [9,10,20].…”

“…Creep tests were carried out using the same three-point bending setup, sample dimensions, and DMA equipment. A static stress value of 2 MPa was applied at the center point along the length of the sample for 10 min after conditioning at 308C, and creep strain was measured as a function of time (30 min) at constant temperature (308C) [9,12].…”

“…where r 0 is the stress, E M is the elastic modulus of the Maxwell model (spring), E K is the elastic modulus of the Kelvin model, h M and h K are the viscosities of Maxwell and Kelvin dashpots, respectively. The first term is a constant related to the deformation of the Maxwell model, the second represents the early creep stage, and the third the creep trend at a sufficiently long time [9]. The interfacial behavior was investigated using shortbeam test, following ASTM D2344-13 using a span-tothickness ratio of 4:1.…”

“…The structural change in response of temperature variation is then more pronounced. However, as the ply angle increases, the Burger's model fitting becomes unsuitable, which can be associated with higher mobility degree due to thermal effects [9].…”

“…For composites, creep resistance is directly associated with viscoelastic strain and fiber/ matrix interfacial behavior. As temperature, stress, and time are crucial parameters to describe viscoelastic behavior, especially when the fiber/matrix coupling needs to be assessed, several models have been proposed to predict long-term creep behavior of composites [9][10][11].…”

This article focuses on the investigation of the interfacial and creep characteristics of carbon fiber‐reinforced epoxy laminates at different fiber orientations. Flat unidirectional 12‐layer laminates were manufactured by dry‐filament winding and cured under hot compression. The following winding sequences were studied: [0]12, [30]12, [45]12, [60]12, and [90]12. Short‐beam testing aided by microscopy and dynamic mechanical analysis were used to assess interfacial characteristics and creep behavior of the laminates. Short beam strength and creep behavior were strongly influenced by fiber orientation. Short beam strength decreased 270%, and only the laminates wound at 0° presented delamination purely at the mid‐plane. Fiber/matrix stress transfer is more efficient for laminates wound at 0°, providing better creep behavior. Dynamic mechanical analysis results indicated the storage modulus to be dependent on the ply angle. Findley's and Burger's fitting were used to analyze creep data from the DMA and correlate structure and property of the composites. The creep strain increases from longitudinal to transversal fiber orientation and by increasing the temperature. At higher temperatures, samples longitudinally oriented exhibited an elastic behavior, with good agreement with the Findley's model. POLYM.

Seersucker woven fabrics are increasingly used in the textile industry. Unfortunately, their popularity is limited due to the lack of standards and parameterization of their structure. Thus, the designer of the finished product (clothing, bedding, or decorative items) has problems with ordering a fabric with a specific structure and properties. In this context, it is necessary to parameterize them. This paper presents a method for measuring the surface geometry of seersucker woven fabrics using laser techniques. The surface geometry of the seersucker woven fabric was determined using adapted roughness parameters, such as Wz, Ra, and Rz, as well as by using a hypsometric map.
