This study deals with the tensile drawing behavior of a polylactide material containing 4% d-stereoisomer units, in amorphous state. The draw temperature domain spanned from glass transition to onset thermal crystallization, namely 70−100 °C. stress−strain curves exhibit strain-hardening strongly sensitive regarding both and slope phenomenon. A detailed structural investigation reveals that various strain-induced phase changes take place depending on temperature. For Td = 70 °C, mesomorphic...
Fibers from milkweed, which grows in Quebec (Canada), offer a distinct and outstanding advantage compared to other natural fibers: their ultra-lightweight hollow structure provides excellent acoustic thermal insulation properties for the automobile industry. To highlight of milkweed fibers reduce use synthetic materials vehicles, nonwoven carpeting made blend polylactic acid (PLA) was produced using air-laid process. Some nonwovens were compressed investigate effects increased mass per unit...
The transfer matrix method (TMM) is used conventionally to predict the acoustic properties of laterally infinite homogeneous layers assembled in series form a multilayer. In this work, parallel assembly process matrices model heterogeneous materials such as patchworks, mosaics, or collection elements parallel. method, it assumed that each element can be modeled by 2 × matrix, and no diffusion exists between elements. resulting also with classical TMM. validated comparison finite (FE)...
Natural fibers have been approved as an excellent alternative for traditional reinforcements in polymer composites. However, the main disadvantage of natural is their poor interaction with polymeric matrices due to hydrophilic nature. In order improve compatibility composite reinforcement, surface treatments are required. Silane treatment has widely used modify hygroscopic properties fibers. this study, a new method silane developed without prehydrolysis and curing/dehydration silanol...

The crystallization behavior and the crystalline structure of nylon6-clay nanocomposites are investigated with regard to processing conditions thermal treatment. Microextruded bulk samples as well blown films under concern. often reported nucleating effect clay particles is shown strongly depend on parameters prior solidification step, namely, shear intensity which promotes self-nucleation temperature melt regulates density these unstable nuclei. MMT content influences kinetics via...
Flax fibers have found widespread use in eco-composite materials because of their remarkable mechanical properties compared to glass fibers. However, low stability limits on a larger scale when employed hot or humid environments. Therefore, the surfaces should be modified before composite process provide best interfacial interactions and increase dispersion natural To tackle this problem, two kinds modifications can considered: wet dry modifications. This research explores different methods...
Significant progress has been made in recent years the use of atmospheric pressure plasma techniques for surface modification. This research focused on beneficial effects these processes natural by-products, specifically those involving fiber-based materials. The study explored deposition hydrophobic organosilicon-like thin films onto flax fibres through plasma-enhanced chemical vapour (PECVD), using tetramethylcyclotetrasiloxane (TMCTS) as precursor. After successful fibres, polylactic acid...
Fiber treatments to enhance interfacial adhesion in natural fiber-reinforced composites generally induce the use of many chemicals. To address this issue, present work aimed develop innovative and ecological fiber produce 100%-green composites, by investigating between modified flax fibers polylactic acid (PLA) using lignin tannin, two types eco-friendly polyphenolic compounds derived from waste or paper industry byproducts. The surface modification was performed a dip-coating method...
