“…목재는 변형이 쉽게 발생되기 때 문에 일반적으로 열처리를 많이 사용한다. 열처리 조 건은 온도와 시간에 따른 변화를 주어 열처리를 진행 하는 것에서부터, 고온 고압을 이용하며, 질소나 아르 곤 조건에서 건조과정을 거쳐 목재의 변형을 최소화 시키는 연구, 과열증기를 이용한 열처리 목재에 대한 연구도 진행되고 있다 [9][10][11]. 목재 내부에 존재하는 미 세 변형을 최소화하기 위해서는 목재 표면에 세라믹 코팅을 진행하거나 목재의 표면을 개질하는 연구도 진행되고 있다 [12][13][14].…”

Stone board for the rock bed was needed to reduce weight using thin thickness and reinforced materials. In this work, stone/wood board for rock bed was studied. Stone and wood were attached to reduce total weight of stone for rock bed. For reinforcing wood heat treatment method was used to change surface and mechanical properties. Mechanical strength of heat treated wood increased more than neat condition. The optimum heat treatment condition was set on 100°C under tensile, flexural loads whereas surface energy was also obtained by contact angle measurement. Optimum adhesive condition was to get the maximum adhesion between stone and wood. Lap shear test was performed for stone/wood board with different adhesives such as amine type epoxy, polyurethane, chloro-rubber and vinyl chloride acetate type. Fracture surface of lap shear test was shown at wood fracture part on stone using amine type epoxy adhesive. It was found that for high adhesion between stone and wood the optimum adhesive was epoxy type for the rock bed.

“…These observations were also confirmed by the finite element analysis results, which showed that water dispersion in epoxy layer has a noticeable impact on its strength. In [21] the effect of moisture on the adhesive interface was investigated, in FRP-wood joints. The authors used atomistic-level analyses supported by experimental evaluation of the studied phenomenon.…”

“…It is focused on different types of tensile and compression tests of composite material for aerospace applications. This paper aims to investigate the laws of deformation and failure of layered CFRP, reinforced with multidirectional fibers , not only at room temperature (RT), but also at low (–54°C) and high (71°C) temperatures . Its purpose is to develop a numerical approach as support of traditional tests, able to estimate the mechanical properties of many CFRP materials only by varying some parameters in a simplified numerical model: percentage of each component, number of plies and fiber's orientation .…”

The use of new Composites Fibers Reinforced Plastics materials for structural applications in aerospace industry is fast increasing in the last years. Ensuring high performances requires a deep knowledge of the mechanical behavior of the composite components subjected to different workloads. Components are subjected to strict environmental conditions that are typical of flight settings, as cold temperature and/or elevated temperature close to engines. In the typical assembly of composites, multiple layers are stacked together with a given sequence. Layers could be organized with different angles, different sequences and different technological process for providing specific mechanical properties that need to be studied. The possibility to introduce new parameters, able to improve mechanical properties of composites is also investigated. It refers to an unconventional fibers orientation combined with the through‐the‐thickness stitching on the in‐plane mechanical properties of composites. Conventional carbon fibers orientation is generally referred to a Cartesian coordinate system, in which fibers are arranging in bundles along different angle orientations respect to the zero lamina. The opportunity to use a polar coordinate system of continues carbon tow is introduced to create specimens as well as complex geometry components easily. The application of this technique aims to introduce some advantages in the material's manufacturing process and if compared with the conventional strategy seems to be very promising since it appears to be very efficient in stopping delamination phenomenon.
