“…This is especially beneficial in evaluating light and ultra-light materials where touching or adding mass to the structure will influence the results. Thus, the acquisition of response function using the IET method is well established in the aerospace industry, where the need to test fragile, lightweight structures is especially useful [ 30 , 31 ]. In the case of such measurement, sophisticated equipment, such as a 3D Laser Doppler Vibrometer, is used to perform IET measurements ( Figure 1 d) [ 18 , 32 ].…”

The Impulse Excitation Technique (IET) is one of the most useful testing methods for evaluating or calculating some material properties. This can be useful to evaluate and confirm that the material ordered is what was delivered. In the case of unknown materials, where their properties are required by simulation software, this is also a quick way to obtain mechanical properties and thus improve the simulation quality. The main drawback of the method is the requirement for a specialized sensor and acquisition system and a well-trained engineer to prepare the setup and analyze the results. The article evaluates the possibility of using a low-cost solution in the form of a mobile device microphone as a way to obtain data, which after the Fast Fourier Transform (FFT), allows to obtain frequency response graphs and use the IET method procedure to calculate the mechanical properties of the samples. The data obtained by the mobile device are compared with the data obtained by professional sensors and data acquisition systems. The results confirm that for typical homogenous materials, the mobile phone is a cheap and reliable alternative for fast, on-the-go material quality inspections and can be introduced even in small companies and on construction sites. Additionally, this kind of approach does not require specific knowledge of sensing technology, signal treatment, or data analysis and can be performed by any assigned employee, who can receive the quality check information immediately on-site. Additionally, the presented procedure allows data collection and transfer to the cloud for future references and additional information extraction. This element is fundamental for introducing sensing technologies under the Industry 4.0 concept.

Coir fibre, derived from the husk of coconuts, is a natural resource and they are biodegradable and renewable. By incorporating them, any product can become more lightweight and durable, meeting the global desire for eco-friendly and efficient designs. This study has the potential to significantly alter the design of components such as switches and enclosures and it has an international research impact on engineering applications. Coir fibres and Hexagonal-Boron Nitride (h-BN) possess superior mechanical, thermal and physical qualities when reinforced with polymers. Hence novel study is carried out to examinecoir fibre/ h-BN reinforcement in epoxy polymer composites.. Response Surface Methodology via Box-Behnken Design (BBD) is utilized to investigate the mechanical properties such as Tensile Strength, Impact Strength and Young’s Modulus of coir fibre/ h-BN reinforced epoxy polymer composite. The effect of input parameters onresponse is evaluated through regression equation and analysis of variance by using statistical Minitab software. The response optimization represents the maximum Young’s modulus (1597 MPa) by combining coir fibre (5 wt.%), Coir fibre powder size (75 µm) and h-BN (1 wt.%). The response optimization portrays the maximum Ultimate Tensile strength(36.83 MPa) by combining coir fibre (1 wt.%), coir fibre powder size (220 µm) and h-BN (3.78 wt.%). The response optimization reveals the maximum Impact strength (98.35 J/m2) by combining coir fibre (5 wt.%), coir fibre powder size (225 µm) and h-BN(1 wt.%). This work emphasises the use of composite materials that are environmental friendly in a variety of industries such as automotive, electrical, etc.

“…Also, knowing the behavior of reinforced plastic composites via a predictive model is vital because such knowledge can help improve the mechanical properties of the composites by using the appropriate mix ratios [35,36]. Response surface methodology (RSM), introduced by Box and Wilson [32,37], has been used in previous research work to optimize the conditions for the manufacturing of composites [38][39][40]. Also, the Box-Behnken design and the central composite design are the two most dominant designs utilized in RSM [37,41].…”

“…Nevertheless, among RSM, the Box-Behnken design is far better since it does not only have axial points, but all design points fall within the safe [36,[42][43][44]. The elastic constants of a coir fiber powder-reinforced plasticized polyvinyl chloride composite were investigated by means of impulsive excitation vibration by [32]. In their study, the optimization of the elastic constants was carried out using Box-Behnken experimental design, and this was based on response surface methodology, which has three factors: fiber content (wt.%), fiber size (μm) and chemical treatments.…”

In this study, the input factors (PVC, rattan, plantain peduncle, and temperature) and the responses (flexural strength and modulus of elasticity) of an experimental design to reinforce PVC composite were investigated. The assessment of suitability and ultimately the choice of the models were done based on the values of statistical parameters like coefficient of determination (R2 value), p value, F value, etc. The experimental data was carried out by fitting a second-order model in the Design Expert model library to the data to estimate the unknown model parameters. This process was accomplished by applying multiple regression analyses to the data. The optimum values of the responses were obtained by numerical optimization based on the criterion of desirability. The results obtained showed that the design was adequate, and the models developed from it were useful because the off-diagonal values were close to zero. Also, increasing the proportion of PVC resulted in a steep and significant increase in the flexural strength of the composite. More so, this trend was similar to the flexural strength for the response surface and the corresponding contour plots representing the relationship between PVC, rattan, and modulus of elasticity. Besides, at higher temperatures, the PVC material could act as a binder, which results in a strong interaction between the components of the composite material.
